Juju Command reference
You can get a list of all Juju commands by invoking juju help commands in a
terminal.
To drill down into each command use juju help <command name>.
This same information is also provided below. Click on the triangle alongside a command to view that command's entry.
actions
Usage: juju actions [options] <application name>
Summary:
List actions defined for an application.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
--format (= default)
Specify output format (default|json|tabular|yaml)
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
-o, --output (= "")
Specify an output file
--schema (= false)
Display the full action schema
Details:
List the actions available to run on the target application, with a short description. To show the full schema for the actions, use --schema.
For more information, see also the 'run-action' command, which executes actions.
Aliases:
list-actions
add-cloud
Usage: juju add-cloud [options] <cloud name> <cloud definition file>
Summary:
Adds a user-defined cloud to Juju from among known cloud types.
Options:
-f (= "")
The path to a cloud definition file
--replace (= false)
Overwrite any existing cloud information
Details:
A cloud definition file has the following YAML format:
clouds:
mycloud:
type: openstack
auth-types: [ userpass ]
regions:
london:
endpoint: https://london.mycloud.com:35574/v3.0/
If the named cloud already exists, the --replace option is required to
overwrite its configuration.
Known cloud types: azure, cloudsigma, ec2, gce, joyent, lxd, maas, manual, openstack, rackspace
Examples:
juju add-cloud mycloud ~/mycloud.yaml
See also:
add-credential
Usage: juju add-credential [options] <cloud name>
Summary:
Adds or replaces credentials for a cloud.
Options:
-f (= "")
The YAML file containing credentials to add
--replace (= false)
Overwrite existing credential information
Details:
The user is prompted to add credentials interactively if a YAML-formatted credentials file is not specified. Here is a sample credentials file:
credentials:
aws:
<credential name>:
auth-type: access-key
access-key: <key>
secret-key: <key>
azure:
<credential name>:
auth-type: service-principal-secret
application-id: <uuid1>
application-password: <password>
subscription-id: <uuid2>
A "credential name" is arbitrary and is used solely to represent a set of credentials, of which there may be multiple per cloud.
The --replace option is required if credential information for the named
cloud already exists. All such information will be overwritten.
This command does not set default regions nor default credentials. Note that if only one credential name exists, it will become the effective default credential.
For credentials which are already in use by tools other than Juju, juju
autoload-credentials may be used.
When Juju needs credentials for a cloud, i) if there are multiple available; ii) there's no set default; iii) and one is not specified ('-- credential'), an error will be emitted.
Examples:
juju add-credential google
juju add-credential aws -f ~/credentials.yaml

-n (= 1)
The number of machines to add
--series (= "")
The charm series
Details:
Juju supports adding machines using provider-specific machine instances (EC2 instances, OpenStack servers, MAAS nodes, etc.); existing machines running a supported operating system (see "manual provisioning" below), and containers on machines. Machines are created in a clean state and ready to have units deployed.
Without any parameters, add machine will allocate a new provider-specific machine (multiple, if "-n" is provided). When adding a new machine, you may specify constraints for the machine to be provisioned; the provider will interpret these constraints in order to decide what kind of machine to allocate.
If a container type is specified (e.g. "lxd"), then add machine will
allocate a container of that type on a new provider-specific machine. It is
also possible to add containers to existing machines using the format
Manual provisioning is the process of installing Juju on an existing machine and bringing it under Juju's management; currently this requires that the machine be running Ubuntu, that it be accessible via SSH, and be running on the same network as the API server.
It is possible to override or augment constraints by passing provider-specific "placement directives" as an argument; these give the provider additional information about how to allocate the machine. For example, one can direct the MAAS provider to acquire a particular node by specifying its hostname.
Examples:
juju add-machine (starts a new machine)
juju add-machine -n 2 (starts 2 new machines)
juju add-machine lxd (starts a new machine with an lxd container)
juju add-machine lxd -n 2 (starts 2 new machines with an lxd container)
juju add-machine lxd:4 (starts a new lxd container on machine 4)
juju add-machine --constraints mem=8G (starts a machine with at least 8GB RAM)
juju add-machine ssh:user@10.10.0.3 (manually provisions machine with ssh)
juju add-machine winrm:user@10.10.0.3 (manually provisions machine with winrm)
juju add-machine zone=us-east-1a (start a machine in zone us-east-1a on AWS)
juju add-machine maas2.name (acquire machine maas2.name on MAAS)

add-model
Usage: juju add-model [options] <model name> [cloud|region|(cloud/region)]
Summary:
Adds a hosted model.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-c, --controller (= "")
Controller to operate in
--config (= )
Path to YAML model configuration file or individual options (--config config.yaml [--config key=value ...])
--credential (= "")
Credential used to add the model
--no-switch (= false)
Do not switch to the newly created model
--owner (= "")
The owner of the new model if not the current user
Details:
Adding a model is typically done in order to run a specific workload.
To add a model, you must specify a model name. Model names can be duplicated across controllers but must be unique per user for any given controller. In other words, Alice and Bob can each have their own model called "secret" but Alice can have only one model called "secret" in a controller.
Model names may only contain lowercase letters, digits and hyphens, and may not start with a hyphen.
To add a model, Juju requires a credential:
* if you have a default (or just one) credential defined at client
(i.e. in credentials.yaml), then juju will use that;
* if you have no default (and multiple) credentials defined at the client,
then you must specify one using --credential;
* as the admin user you can omit the credential,
and the credential used to bootstrap will be used.
To add a credential for add-model, use one of the "juju add-credential" or "juju autoload-credentials" commands. These will add credentials to the Juju client, which "juju add-model" will upload to the controller as necessary.
You may also supply model-specific configuration as well as a cloud/region to which this model will be deployed. The cloud/region and credentials are the ones used to create any future resources within the model.
If no cloud/region is specified, then the model will be deployed to the same cloud/region as the controller model. If a region is specified without a cloud qualifier, then it is assumed to be in the same cloud as the controller model. It is not currently possible for a controller to manage multiple clouds, so the only valid cloud is the same cloud as the controller model is deployed to. This may change in a future release.
Examples:
juju add-model mymodel
juju add-model mymodel us-east-1
juju add-model mymodel aws/us-east-1
juju add-model mymodel --config my-config.yaml --config image-stream=daily
juju add-model mymodel --credential credential_name --config authorized-keys="ssh-rsa ..."
add-relation
Usage: juju add-relation [options] <application1>[:<endpoint name1>] <application2>[:<endpoint name2>]
Summary:
Add a relation between two application endpoints.
Options:
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
--via (= "")
for cross model relations, specify the egress subnets for outbound traffic
Details:
Add a relation between 2 local application endpoints or a local endpoint and a remote application endpoint. Adding a relation between two remote application endpoints is not supported. Application endpoints can be identified either by:
<application name>[:<relation name>]
where application name supplied without relation will be internally expanded to be well-formed
or
or
For a cross model relation, if the consuming side is behind a firewall and/or NAT is used for outbound traffic, it is possible to use the --via option to inform the offering side the source of traffic so that any required firewall ports may be opened.
Examples:
$ juju add-relation wordpress mysql
where "wordpress" and "mysql" will be internally expanded to "wordpress:db" and "mysql:server" respectively
$ juju add-relation wordpress someone/prod.mysql
where "wordpress" will be internally expanded to "wordpress:db"
$ juju add-relation wordpress someone/prod.mysql --via 192.168.0.0/16
$ juju add-relation wordpress someone/prod.mysql --via 192.168.0.0/16,10.0.0.0/8
Aliases:

add-space
Usage: juju add-space [options] <name> [<CIDR1> <CIDR2> ...]
Summary:
Add a new network space.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Adds a new space with the given name and associates the given (optional) list of existing subnet CIDRs with it.
add-ssh-key
Usage: juju add-ssh-key [options] <ssh key> ...
Summary:
Adds a public SSH key to a model.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Juju maintains a per-model cache of public SSH keys which it copies to each unit (including units already deployed). By default this includes the key of the user who created the model (assuming it is stored in the default location ~/.ssh/). Additional keys may be added with this command, quoting the entire public key as an argument.
Examples:
juju add-ssh-key "ssh-rsa qYfS5LieM79HIOr535ret6xy
AAAAB3NzaC1yc2EAAAADAQA6fgBAAABAQCygc6Rc9XgHdhQqTJ

add-storage
Usage: juju add-storage [options] <unit name> <charm storage name>[=<storage constraints>] ...
Summary:
Adds unit storage dynamically.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Add storage instances to a unit dynamically using provided storage directives. Specify a unit and a storage specification in the same format as passed to juju deploy --storage=”...”.
A storage directive consists of a storage name as per charm specification and storage constraints, e.g. pool, count, size.
The acceptable format for storage constraints is a comma separated sequence of: POOL, COUNT, and SIZE, where POOL identifies the storage pool. POOL can be a string starting with a letter, followed by zero or more digits or letters optionally separated by hyphens.
COUNT is a positive integer indicating how many instances
of the storage to create. If unspecified, and SIZE is
specified, COUNT defaults to 1.
SIZE describes the minimum size of the storage instances to
create. SIZE is a floating point number and multiplier from
the set (M, G, T, P, E, Z, Y), which are all treated as
powers of 1024.
Storage constraints can be optionally ommitted.
Model default values will be used for all ommitted constraint values.
There is no need to comma-separate ommitted constraints.
Examples:
# Add 3 ebs storage instances for "data" storage to unit u/0:
juju add-storage u/0 data=ebs,1024,3
or
juju add-storage u/0 data=ebs,3
or
juju add-storage u/0 data=ebs,,3
# Add 1 storage instances for "data" storage to unit u/0
# using default model provider pool:
juju add-storage u/0 data=1
or
juju add-storage u/0 data
add-subnet
Usage: juju add-subnet [options] <CIDR>|<provider-id> <space> [<zone1> <zone2> ...]
Summary:
Add an existing subnet to Juju.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Adds an existing subnet to Juju, making it available for use. Unlike "juju add-subnet", this command does not create a new subnet, so it is supported on a wider variety of clouds (where SDN features are not available, e.g. MAAS). The subnet will be associated with the given existing Juju network space.
Subnets can be referenced by either their CIDR or ProviderId (if the provider supports it). If CIDR is used an multiple subnets have the same CIDR, an error will be returned, including the list of possible provider IDs uniquely identifying each subnet.
Any availablility zones associated with the added subnet are automatically discovered using the cloud API (if supported). If this is not possible, since any subnet needs to be part of at least one zone, specifying zone(s) is required.
add-unit
Usage: juju add-unit [options] <application name>
Summary:
Adds one or more units to a deployed application.
Options:
--attach-storage (= )
Existing storage to attach to the deployed unit
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
-n, --num-units (= 1)
Number of units to add
--to (= "")
The machine and/or container to deploy the unit in (bypasses constraints)
Details:
The add-unit command adds units to an existing application. It is used to scale out an application for improved performance or availability.
Many charms will seamlessly support horizontal scaling while others may need an additional application support (e.g. a separate load balancer). See the documentation for specfic charms to check how scale-out is supported.
By default, units are deployed to newly provisioned machines in accordance with any application or model constraints. This command also supports the placement directive ("--to") for targeting specific machines or containers, which will bypass application and model constraints.
Examples:
Add five units of wordpress on five new machines: juju add-unit wordpress -n 5 Add a unit of mysql to machine 23 (which already exists): juju add-unit mysql --to 23 Add two units of mysql to machines 3 and 4: juju add-unit mysql -n 2 --to 3,4 Add three units of mysql to machine 7: juju add-unit mysql -n 3 --to 7,7,7 Add three units of mysql, one to machine 3 and the others to new machines: juju add-unit mysql -n 3 --to 7 Add a unit into a new LXD container on machine 7: juju add-unit mysql --to lxd:7 Add two units into two new LXD containers on machine 7: juju add-unit mysql -n 2 --to lxd:7,lxd:7 Add a unit of mariadb to LXD container number 3 on machine 24: juju add-unit mariadb --to 24/lxd/3 Add a unit of mariadb to LXD container on a new machine: juju add-unit mariadb --to lxd

Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-c, --controller (= "")
Controller to operate in
Details:
The user's details are stored within the controller and will be removed when the controller is destroyed.
A user unique registration string will be printed. This registration string must be used by the newly added user as supplied to complete the registration process. Some machine providers will require the user to be in possession of certain credentials in order to create a model.
Examples:
juju add-user bob
juju add-user --controller mycontroller bob

Do not use web browser for authentication
-c, --controller (= "")
Controller to operate in
--yes (= false)
Agree to terms non interactively
Details:
Agree to the terms required by a charm.
When deploying a charm that requires agreement to terms, use 'juju agree' to view the terms and agree to them. Then the charm may be deployed.
Once you have agreed to terms, you will not be prompted to view them again.
Examples:
# Displays terms for somePlan revision 1 and prompts for agreement.
juju agree somePlan/1
# Displays the terms for revision 1 of somePlan, revision 2 of otherPlan,
# and prompts for agreement.
juju agree somePlan/1 otherPlan/2
# Agrees to the terms without prompting.
juju agree somePlan/1 otherPlan/2 --yes

--to (= "")
Placement directive indicating an instance to bootstrap
Details:
Used without arguments, bootstrap will step you through the process of initializing a Juju cloud environment. Initialization consists of creating a 'controller' model and provisioning a machine to act as controller.
We recommend you call your controller ‘username-region’ e.g. ‘fred-us-east-1’ See --clouds for a list of clouds and credentials.
See --regions juju add-credential).
The 'controller' model typically does not run workloads. It should remain
pristine to run and manage Juju's own infrastructure for the corresponding
cloud. Additional (hosted) models should be created with juju create-
model for workload purposes.
Note that a 'default' model is also created and becomes the current model of the environment once the command completes. It can be discarded if other models are created.
If '--bootstrap-constraints' is used, its values will also apply to any future controllers provisioned for high availability (HA).
If '--constraints' is used, its values will be set as the default
constraints for all future workload machines in the model, exactly as if
the constraints were set with juju set-model-constraints.
It is possible to override constraints and the automatic machine selection
algorithm by assigning a "placement directive" via the '--to' option. This
dictates what machine to use for the controller. This would typically be
used with the MAAS provider ('--to
Available keys for use with --config can be found here:
https://jujucharms.com/docs/stable/controllers-config
https://jujucharms.com/docs/stable/models-config
You can change the default timeout and retry delays used during the bootstrap by changing the following settings in your configuration (all values represent number of seconds):
# How long to wait for a connection to the controller
bootstrap-timeout: 600 # default: 10 minutes
# How long to wait between connection attempts to a controller
address.
bootstrap-retry-delay: 5 # default: 5 seconds
# How often to refresh controller addresses from the API server.
bootstrap-addresses-delay: 10 # default: 10 seconds
Private clouds may need to specify their own custom image metadata and tools/agent. Use '--metadata-source' whose value is a local directory. By default, the Juju version of the agent binary that is downloaded and installed on all models for the new controller will be the same as that of the Juju client used to perform the bootstrap.
However, a user can specify a different agent version via '--agent-version' option to bootstrap command. Juju will use this version for models' agents as long as the client's version is from the same Juju release series.
In other words, a 2.2.1 client can bootstrap any 2.2.x agents but cannot bootstrap any 2.0.x or 2.1.x agents.
The agent version can be specified a simple numeric version, e.g. 2.2.4. For example, at the time when 2.3.0, 2.3.1 and 2.3.2 are released and your agent stream is 'released' (default), then a 2.3.1 client can bootstrap: * 2.3.0 controller by running '... bootstrap --agent-version=2.3.0 ...'; * 2.3.1 controller by running '... bootstrap ...'; * 2.3.2 controller by running 'bootstrap --auto-upgrade'.
However, if this client has a copy of codebase, then a local copy of Juju will be built and bootstrapped - 2.3.1.1.
Examples:
juju bootstrap
juju bootstrap --clouds
juju bootstrap --regions aws
juju bootstrap aws
juju bootstrap aws/us-east-1
juju bootstrap google joe-us-east1

Summary:
Changes the password for the current or specified Juju user.
Options:
-c, --controller (= "")
Controller to operate in
--reset (= false)
Reset user password
Details:
The user is, by default, the current user. The latter can be confirmed with
the juju show-user command.
A controller administrator can change the password for another user on the specified controller. If no controller is specified, the current controller will be used.
A controller administrator can also reset the password for another user.
This will invalidate any password or registration string
that was previously issued, and issue a new registration string to be used with
juju register.
Examples:
juju change-user-password
juju change-user-password bob
juju change-user-password bob --reset
juju change-user-password -c another-known-controller
juju change-user-password bob --controller another-known-controller

See also:
create-storage-pool
Usage: juju create-storage-pool [options] <name> <provider> [<key>=<value> [<key>=<value>...]]
Summary:
Create or define a storage pool.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Pools are a mechanism for administrators to define sources of storage that they will use to satisfy application storage requirements.
A single pool might be used for storage from units of many different applications - it is a resource from which different stores may be drawn.
A pool describes provider-specific parameters for creating storage, such as performance (e.g. IOPS), media type (e.g. magnetic vs. SSD), or durability.
For many providers, there will be a shared resource where storage can be requested (e.g. EBS in amazon).
Creating pools there maps provider specific settings into named resources that can be used during deployment.
Pools defined at the model level are easily reused across applications. Pool creation requires a pool name, the provider type and attributes for configuration as space-separated pairs, e.g. tags, size, path, etc.
create-wallet
Usage: juju create-wallet [options]
Summary:
Create a new wallet.
Options:
-B, --no-browser-login (= false)

credentials
Usage: juju credentials [options] [<cloud name>]
Summary:
Lists credentials for a cloud.
Options:
--format (= tabular)
Specify output format (json|tabular|yaml)
-o, --output (= "")
Specify an output file
--show-secrets (= false)
Show secrets
Details:
Credentials are used with juju bootstrap and juju add-model.
An arbitrary "credential name" is used to represent credentials, which are
added either via juju add-credential or juju autoload-credentials.
Note that there can be multiple sets of credentials and thus multiple
names.
Actual authentication material is exposed with the '--show-secrets' option.
A controller and subsequently created models can be created with a
different set of credentials but any action taken within the model (e.g.:
juju deploy; juju add-unit) applies the set used to create the model.
Recall that when a controller is created a 'default' model is also
created.
Credentials denoted with an asterisk '*' are currently set as the default for the given cloud.
Examples:
juju credentials
juju credentials aws
juju credentials --format yaml --show-secrets

--tail (= false)
Wait for new logs
--utc (= false)
Show times in UTC
-x, --exclude (= )
Do not show log messages for these entities
Details:
This command provides access to all logged Juju activity on a per-model basis. By default, the logs for the currently select model are shown.
Each log line is emitted in this format:
<entity> <timestamp> <log-level> <module>:<line-no> <message>
The "entity" is the source of the message: a machine or unit. The names for
machines and units can be seen in the output of juju status.
The '--include' and '--exclude' options filter by entity. The entity can be a machine, unit, or application.
The '--include-module' and '--exclude-module' options filter by (dotted) logging module name. The module name can be truncated such that all loggers with the prefix will match.
The filtering options combine as follows:
All --include options are logically ORed together.
All --exclude options are logically ORed together.
All --include-module options are logically ORed together.
All --exclude-module options are logically ORed together.
The combined --include, --exclude, --include-module and --exclude-module selections are logically ANDed to form the complete filter.
Examples:
Exclude all machine 0 messages; show a maximum of 100 lines; and continue to append filtered messages: juju debug-log --exclude machine-0 --lines 100 Include only unit mysql/0 messages; show a maximum of 50 lines; and then exit: juju debug-log -T --include unit-mysql-0 --lines 50 Show all messages from unit apache2/3 or machine 1 and then exit: juju debug-log -T --replay --include unit-apache2-3 --include machine-1 Show all juju.worker.uniter logging module messages that are also unit wordpress/0 messages, and then show any new log messages which match the filter: juju debug-log --replay --include-module juju.worker.uniter \ --include unit-wordpress-0 Show all messages from the juju.worker.uniter module, except those sent from machine-3 or machine-4, and then stop: juju debug-log --replay --no-tail --include-module juju.worker.uniter \ --exclude machine-3 \ --exclude machine-4 To see all WARNING and ERROR messages and then continue showing any new WARNING and ERROR messages as they are logged: juju debug-log --replay --level WARNING

--resource (= )
Resource to be uploaded to the controller
--series (= "")
The series on which to deploy
--storage (= )
Charm storage constraints
--to (= "")
The machine and/or container to deploy the unit in (bypasses constraints)
Details:
For cs:trusty/mysql mysql trusty/mysql
For cs:~user/trusty/mysql ~user/mysql
For cs:bundle/mediawiki-single mediawiki-single bundle/mediawiki-single
The current series for charms is determined first by the 'default-series' model setting, followed by the preferred series for the charm in the charm store. In these cases, a versioned charm URL will be expanded as expected (for example, mysql-33 becomes cs:precise/mysql-33).
Charms may also be deployed from a user specified path. In this case, the path to the charm is specified along with an optional series.
juju deploy /path/to/charm --series trusty
If '--series' is not specified, the charm's default series is used. The default series for a charm is the first one specified in the charm metadata. If the specified series is not supported by the charm, this results in an error, unless '--force' is used.
juju deploy /path/to/charm --series wily --force
Local bundles are specified with a direct path to a bundle.yaml file. For example:
juju deploy /path/to/bundle/openstack/bundle.yaml
If an 'application name' is not provided, the application name used is the 'charm or bundle' name. A user-supplied 'application name' must consist only of lower-case letters (a-z), numbers (0-9), and single hyphens (-). The name must begin with a letter and not have a group of all numbers follow a hyphen.
Examples:
Valid: myappname, custom-app, app2-scat-23skidoo
Invalid: myAppName, custom--app, app2-scat-23, areacode-555-info
Constraints can be specified by specifying the '--constraints' option. If the
application is later scaled out with juju add-unit, provisioned machines
will use the same constraints (unless changed by juju set-constraints).
Application configuration values can be specified using '--config' option. This
option accepts either a path to a yaml-formatted file or a key=value pair.
Configuration file provided should be in format
juju deploy mediawiki --config name='my media wiki'
When specifying more than one option value, use: juju deploy mediawiki --config name='my media wiki' --config debug=true Care must be taken when specifying more than one configuration via '--config' option - any later values will override those specified earlier. For example, when calling juju deploy mediawiki --config name='my media wiki' --config mycfg.yaml
if mycfg.yaml contained a value for 'name', it will be used in preference
to the earlier 'my media wiki' value.
The same applies to single value options. For example, when calling
juju deploy mediawiki --config name='a media wiki' --config name='my wiki'
the value 'my wiki' will be used for the option 'name'.
Resources may be uploaded by specifying the '--resource' option followed by a
name=filepath pair. This option may be repeated more than once to upload more
than one resource.
juju deploy foo --resource bar=/some/file.tgz --resource baz=./docs/cfg.xml
Where 'bar' and 'baz' are resources named in the metadata for the 'foo' charm.
When using a placement directive to deploy to an existing machine or container
('--to' option), the juju status command should be used for guidance. A few
placement directives are provider-dependent (e.g.: 'zone').
In more complex scenarios, Juju's network spaces are used to partition the
cloud networking layer into sets of subnets. Instances hosting units inside the
same space can communicate with each other without any firewalls. Traffic
crossing space boundaries could be subject to firewall and access restrictions.
Using spaces as deployment targets, rather than their individual subnets,
allows Juju to perform automatic distribution of units across availability zones
to support high availability for applications. Spaces help isolate applications
and their units, both for security purposes and to manage both traffic
segregation and congestion.
When deploying an application or adding machines, the 'spaces' constraint can
be used to define a comma-delimited list of required and forbidden spaces (the
latter prefixed with "^", similar to the 'tags' constraint).
When deploying bundles, machines specified in the bundle are added to the
model as new machines. In order to use the existing machines in the model
rather than create new machines, the option --map-machines=existing can be
used. To specify particular machines for the mapping, multiple comma separated
values of the form "bundle-id=existing-id" can be passed where the bundle-id
and the existing-id refer to top level machine IDs. For example, if there was
a bundle that specified machines 1, 2, and 3, and the model had machines 1, 2,
3 and 4, the following deployment of the bundle would use machines 1 and 2 in
the model for machines 1 and 2 in the bundle and use machine 4 in the model
for the bundle machine 3.
juju deploy some-bundle --map-machines existing,3=4
Only top level machines can be mapped in this way, just as only top level
machines can be defined in the machines section of the bundle.
Examples:
juju deploy mysql (deploy to a new machine)
juju deploy mysql --to 23 (deploy to preexisting machine 23)
juju deploy mysql --to lxd (deploy to a new LXD container on a new machine)
juju deploy mysql --to lxd:25 (deploy to a new LXD container on machine 25)
juju deploy mysql --to 24/lxd/3 (deploy to LXD container 3 on machine 24)
juju deploy mysql -n 2 --to 3,lxd:5
(deploy 2 units, one on machine 3 & one to a new LXD container on machine 5)
juju deploy mysql -n 3 --to 3
(deploy 3 units, one on machine 3 & the remaining two on new machines)
juju deploy mysql -n 5 --constraints mem=8G
(deploy 5 units to machines with at least 8 GB of memory)
juju deploy mysql --to zone=us-east-1a
(provider-dependent; deploy to a specific AZ)
juju deploy mysql --to host.maas
(deploy to a specific MAAS node)
juju deploy haproxy -n 2 --constraints spaces=dmz,^cms,^database
(deploy 2 units to machines that are in the 'dmz' space but not of
the 'cmd' or the 'database' spaces)

destroy-controller
Usage: juju destroy-controller [options] <controller name>
Summary:
Destroys a controller.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
--destroy-all-models (= false)
Destroy all hosted models in the controller
--destroy-storage (= false)
Destroy all storage instances managed by the controller
--release-storage (= false)
Release all storage instances from management of the controller, without destroying them
-y, --yes (= false)
Do not ask for confirmation
Details:
All models (initial model plus all workload/hosted) associated with the
controller will first need to be destroyed, either in advance, or by
specifying --destroy-all-models.
If there is persistent storage in any of the models managed by the
controller, then you must choose to either destroy or release the
storage, using --destroy-storage or --release-storage respectively.
Examples:
# Destroy the controller and all hosted models. If there is
# persistent storage remaining in any of the models, then
# this will prompt you to choose to either destroy or release
# the storage.
juju destroy-controller --destroy-all-models mycontroller
# Destroy the controller and all hosted models, destroying
# any remaining persistent storage.
juju destroy-controller --destroy-all-models --destroy-storage
# Destroy the controller and all hosted models, releasing
# any remaining persistent storage from Juju's control.
juju destroy-controller --destroy-all-models --release-storage
See also:

Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
--destroy-storage (= false)
Destroy all storage instances in the model
--release-storage (= false)
Release all storage instances from the model, and management of the controller, without destroying them
-y, --yes (= false)
Do not prompt for confirmation
Details:
Destroys the specified model. This will result in the non-recoverable removal of all the units operating in the model and any resources stored there. Due to the irreversible nature of the command, it will prompt for confirmation (unless overridden with the '-y' option) before taking any action.
If there is persistent storage in any of the models managed by the controller, then you must choose to either destroy or release the storage, using --destroy-storage or --release-storage respectively.
Examples:
juju destroy-model test
juju destroy-model -y mymodel
juju destroy-model -y mymodel --destroy-storage
juju destroy-model -y mymodel --release-storage

This is done by disabling certain sets of commands from successful execution. Disabled commands must be manually enabled to proceed.
Some commands offer a --force option that can be used to bypass a block. Commands that can be disabled are grouped based on logical operations as follows: "destroy-model" prevents:
destroy-controller
destroy-model
"remove-object" prevents:
destroy-controller
destroy-model
remove-machine
remove-relation
remove-application
remove-unit
"all" prevents:
add-machine
add-relation
add-unit
add-ssh-key
add-user
change-user-password
config
deploy
disable-user
destroy-controller
destroy-model
enable-ha
enable-user
expose
import-ssh-key
model-config
remove-application
remove-machine
remove-relation
remove-ssh-key
remove-unit
resolved
retry-provisioning
run
set-constraints
sync-agents
unexpose
upgrade-charm
upgrade-juju
Examples:
# To allow the model to be destroyed:
juju enable-command destroy-model
# To allow the machines, applications, units and relations to be removed:
juju enable-command remove-object
# To allow changes to the model:
juju enable-command all

enable-destroy-controller
Usage: juju enable-destroy-controller [options]
Summary:
Enable destroy-controller by removing disabled commands in the controller.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-c, --controller (= "")
Controller to operate in
Details:
Any model in the controller that has disabled commands will block a controller from being destroyed.
A controller administrator is able to enable all the commands across all the models in a Juju controller so that the controller can be destoyed if desired.
See also:
enable-ha
Usage: juju enable-ha [options]
Summary:
Ensure that sufficient controllers exist to provide redundancy.
Options:

--to (= "")
The machine(s) to become controllers, bypasses constraints
Details:
To ensure availability of deployed applications, the Juju infrastructure must itself be highly available. The enable-ha command will ensure that the specified number of controller machines are used to make up the controller.
An odd number of controllers is required.
Examples:
# Ensure that the controller is still in highly available mode. If
# there is only 1 controller running, this will ensure there
# are 3 running. If you have previously requested more than 3,
# then that number will be ensured.
juju enable-ha
# Ensure that 5 controllers are available.
juju enable-ha -n 5
# Ensure that 7 controllers are available, with newly created
# controller machines having at least 8GB RAM.
juju enable-ha -n 7 --constraints mem=8G
# Ensure that 7 controllers are available, with machines server1 and
# server2 used first, and if necessary, newly created controller
# machines having at least 8GB RAM.
juju enable-ha -n 7 --to server1,server2 --constraints mem=8G

import-filesystem
Usage: juju import-filesystem [options] <storage-provider> <provider-id> <storage-name>
Summary:
Imports a filesystem into the model.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Import an existing filesystem into the model. This will lead to the model taking ownership of the storage, so you must take care not to import storage that is in use by another Juju model.
To import a filesystem, you must specify three things:
- the storage provider which manages the storage, and with
which the storage will be associated
- the storage provider ID for the filesystem, or
volume that backs the filesystem
- the storage name to assign to the filesystem,
corresponding to the storage name used by a charm
Once a filesystem is imported, Juju will create an associated storage instance using the given storage name.
Examples:
# Import an existing filesystem backed by an EBS volume,
# and assign it the "pgdata" storage name. Juju will
# associate a storage instance ID like "pgdata/0" with
# the volume and filesystem contained within.
juju import-filesystem ebs vol-123456 pgdata
import-ssh-key
Usage: juju import-ssh-key [options] <lp|gh>:<user identity> ...
Summary:
Adds a public SSH key from a trusted identity source to a model.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Juju can add SSH keys to its cache from reliable public sources (currently Launchpad and GitHub), allowing those users SSH access to Juju machines. The user identity supplied is the username on the respective service given by 'lp:' or 'gh:'.
If the user has multiple keys on the service, all the keys will be added.
Once the keys are imported, they can be viewed with the juju ssh-keys
command, where comments will indicate which ones were imported in
this way.
An alternative to this command is the more manual juju add-ssh-key.
Examples:
Import all public keys associated with user account 'phamilton' on the GitHub service: juju import-ssh-key gh:phamilton Multiple identities may be specified in a space delimited list: juju import-ssh-key gh:rheinlein lp:iasmiov gh:hharrison

kill-controller
Usage: juju kill-controller [options] <controller name>
Summary:
Forcibly terminate all machines and other associated resources for a Juju controller.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-t, --timeout (= 5m0s)
Timeout before direct destruction
-y, --yes (= false)
Do not ask for confirmation
Details:
Forcibly destroy the specified controller. If the API server is accessible, this command will attempt to destroy the controller model and all hosted models and their resources.
If the API server is unreachable, the machines of the controller model will be destroyed through the cloud provisioner. If there are additional machines, including machines within hosted models, these machines will not be destroyed and will never be reconnected to the Juju controller being destroyed.
The normal process of killing the controller will involve watching the hosted models as they are brought down in a controlled manner. If for some reason the models do not stop cleanly, there is a default five minute timeout. If no change in the model state occurs for the duration of this timeout, the command will stop watching and destroy the models directly through the cloud provider.

Credentials are used with juju bootstrap and juju add-model.
An arbitrary "credential name" is used to represent credentials, which are
added either via juju add-credential or juju autoload-credentials.
Note that there can be multiple sets of credentials and thus multiple
names.
Actual authentication material is exposed with the '--show-secrets' option.
A controller and subsequently created models can be created with a
different set of credentials but any action taken within the model (e.g.:
juju deploy; juju add-unit) applies the set used to create the model.
Recall that when a controller is created a 'default' model is also
created.
Credentials denoted with an asterisk '*' are currently set as the default for the given cloud.

-c, --controller (= "")
Controller to operate in
-u, --user (= "")
log in as this local user
Details:
By default, the juju login command logs the user into a controller.
The argument to the command can be a public controller host name or alias (see Aliases below).
If no argument is provided, the controller specified with the -c argument will be used, or the current controller if that's not provided.
On success, the current controller is switched to the logged-in controller.
If the user is already logged in, the juju login command does nothing except verify that fact.
If the -u flag is provided, the juju login command will attempt to log into the controller as that user.
After login, a token ("macaroon") will become active. It has an expiration time of 24 hours. Upon expiration, no further Juju commands can be issued and the user will be prompted to log in again.
Aliases
Public controller aliases are provided by a directory service that is queried to find the host name for a given alias.
The URL for the directory service may be configured by setting the environment variable JUJU_DIRECTORY.
Examples:
juju login somepubliccontroller
juju login jimm.jujucharms.com
juju login -u bob

--force (= false)
Force logout when a locally recorded password is detected
Details:
If another client has logged in as the same user, they will remain logged in. This command only affects the local client.
The command will fail if the user has not yet set a password
(juju change-user-password). This scenario is only possible after
juju bootstrapsince juju register sets a password. The
failing behaviour can be overridden with the '--force' option.
If the same user is logged in with another client system, that user session will not be affected by this command; it only affects the local client. By default, the controller is the current controller.
Examples:
juju logout

Usage: juju migrate [options] <model-name> <target-controller-name>
Summary:
Migrate a hosted model to another controller.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
Details:
migrate begins the migration of a model from its current controller to a new controller. This is useful for load balancing when a controller is too busy, or as a way to upgrade a model's controller to a newer Juju version. Once complete, the model's machine and and unit agents will be connected to the new controller. The model will no longer be available at the source controller.
Note that only hosted models can be migrated. Controller models can not be migrated.
If the migration fails for some reason, the model be returned to its original state with the model being managed by the original controller.
In order to start a migration, the target controller must be in the juju client's local configuration cache. See the juju "login" command for details of how to do this.
This command only starts a model migration - it does not wait for its completion. The progress of a migration can be tracked using the "status" command and by consulting the logs.

relate
Usage: juju add-relation [options] <application1>[:<endpoint name1>] <application2>[:<endpoint name2>]
Summary:
Add a relation between two application endpoints.
Options:
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
--via (= "")
for cross model relations, specify the egress subnets for outbound traffic
Details:
Add a relation between 2 local application endpoints or a local endpoint and a remote application endpoint. Adding a relation between two remote application endpoints is not supported. Application endpoints can be identified either by:
<application name>[:<relation name>]
where application name supplied without relation will be internally expanded to be well-formed
or
or
For a cross model relation, if the consuming side is behind a firewall and/or NAT is used for outbound traffic, it is possible to use the --via option to inform the offering side the source of traffic so that any required firewall ports may be opened.
Examples:
$ juju add-relation wordpress mysql
where "wordpress" and "mysql" will be internally expanded to "wordpress:db" and "mysql:server" respectively
$ juju add-relation wordpress someone/prod.mysql
where "wordpress" will be internally expanded to "wordpress:db"
$ juju add-relation wordpress someone/prod.mysql --via 192.168.0.0/16

Details:
Removing an application will terminate any relations that application has, remove all units of the application, and in the case that this leaves machines with no running applications, Juju will also remove the machine. For this reason, you should retrieve any logs or data required from applications and units before removing them. Removing units which are co-located with units of other charms or a Juju controller will not result in the removal of the machine.
Examples:
juju remove-application hadoop
juju remove-application -m test-model mariadb
remove-backup
Usage: juju remove-backup [options] <ID>
Summary:
Remove the specified backup from remote storage.

Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Removing a consumed (SAAS) application will terminate any relations that application has, potentially leaving any related local applications in a non-functional state.
Examples:

--keep-instance (= false)
Do not stop the running cloud instance
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Machines are specified by their numbers, which may be retrieved from the
output of juju status.
Machines responsible for the model cannot be removed.
Machines running units or containers can be removed using the '--force' option; this will also remove those units and containers without giving them an opportunity to shut down cleanly.
Examples:
Remove machine number 5 which has no running units or containers: juju remove-machine 5 Remove machine 6 and any running units or containers: juju remove-machine 6 --force
Remove machine 7 from the Juju model but do not stop the corresponding cloud instance: juju remove-machine 7 --keep-instance

juju remove-offer hosted-mysql
See also:
remove-relation
Usage: juju remove-relation [options] <application1>[:<relation name1>] <application2>[:<relation name2>] | <relation-id>
Summary:
Removes an existing relation between two applications.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
An existing relation between the two specified applications will be removed.
This should not result in either of the applications entering an error state,
but may result in either or both of the applications being unable to continue
normal operation. In the case that there is more than one relation between
two applications it is necessary to specify which is to be removed (see
examples). Relations will automatically be removed when using thejuju
remove-application command.
The relation is specified using the relation endpoint names, eg mysql wordpress, or mediawiki:db mariadb:db
It is also possible to specify the relation ID, if known. This is useful to terminate a relation originating from a different model, where only the ID is known.
Examples:
juju remove-relation mysql wordpress
juju remove-relation 4
In the case of multiple relations, the relation name should be specified at least once - the following examples will all have the same effect: juju remove-relation mediawiki:db mariadb:db juju remove-relation mediawiki mariadb:db juju remove-relation mediawiki:db mariadb

Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Juju maintains a per-model cache of public SSH keys which it copies to each unit. This command will remove a specified key (or space separated list of keys) from the model cache and all current units deployed in that model. The keys to be removed may be specified by the key's fingerprint, or by the text label associated with them.
Examples:
juju remove-ssh-key ubuntu@ubuntu
juju remove-ssh-key 45:7f:33:2c:10:4e:6c:14:e3:a1:a4:c8:b2:e1:34:b4

Examples:
# Remove the detached storage pgdata/0.
juju remove-storage pgdata/0
# Remove the possibly attached storage pgdata/0.
juju remove-storage --force pgdata/0
# Remove the storage pgdata/0, without destroying
# the corresponding cloud storage.

Summary:
Remove application units from the model.
Options:
-B, --no-browser-login (= false)
Do not use web browser for authentication
--destroy-storage (= false)
Destroy storage attached to the unit
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Remove application units from the model.
Units of a application are numbered in sequence upon creation. For example, the fourth unit of wordpress will be designated "wordpress/3". These identifiers can be supplied in a space delimited list to remove unwanted units from the model.
Juju will also remove the machine if the removed unit was the only unit left on that machine (including units in containers).
Removing all units of a application is not equivalent to removing the
application itself; for that, the juju remove-application command
is used.
Examples:
juju remove-unit wordpress/2 wordpress/3 wordpress/4

-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
Restores a backup that was previously created with "juju create-backup". This command creates a new controller and arranges for it to replace the previous controller for a model. It does not restore an existing server to a previous state, but instead creates a new server with equivalent state. As part of restore, all known instances are configured to treat the new controller as their master.
The given constraints will be used to choose the new instance.
If the provided state cannot be restored, this command will fail with an appropriate message. For instance, if the existing bootstrap instance is already running then the command will fail with a message to that effect.

Do not use web browser for authentication
-c, --controller (= "")
Controller to operate in
Details:
By default, the controller is the current controller.
Revoking write access, from a user who has that permission, will leave that user with read access. Revoking read access, however, also revokes write access.
Examples:
Revoke 'read' (and 'write') access from user 'joe' for model 'mymodel': juju revoke joe read mymodel Revoke 'write' access from user 'sam' for models 'model1' and 'model2': juju revoke sam write model1 model2 Revoke 'add-model' access from user 'maria' to the controller: juju revoke maria add-model Revoke 'read' (and 'write') access from user 'joe' for application offer 'fred/prod.hosted-mysql': juju revoke joe read fred/prod.hosted-mysql Revoke 'consume' access from user 'sam' for models 'fred/prod.hosted-mysql' and 'mary/test.hosted-mysql': juju revoke sam consume fred/prod.hosted-mysql mary/test.hosted-mysql

--timeout (= 5m0s)
How long to wait before the remote command is considered to have failed
--unit (= )
One or more unit ids
Details:
Run a shell command on the specified targets. Only admin users of a model are able to use this command.
Targets are specified using either machine ids, application names or unit names. At least one target specifier is needed.
Multiple values can be set for --machine, --application, and --unit by using comma separated values.
If the target is a machine, the command is run as the "root" user on the remote machine.
If the target is an application, the command is run on all units for that application. For example, if there was an application "mysql" and that application had two units, "mysql/0" and "mysql/1", then --application mysql
is equivalent to --unit mysql/0,mysql/1
Commands run for applications or units are executed in a 'hook context' for the unit.
--all is provided as a simple way to run the command on all the machines in the model. If you specify --all you cannot provide additional targets.
Since juju run creates actions, you can query for the status of commands started with juju run by calling "juju show-action-status --name juju-run". If you need to pass flags to the command being run, you must precede the command and its arguments with "--", to tell "juju run" to stop processing those arguments. For example:
juju run --all -- hostname -f

Details:
Queue an Action for execution on a given unit, with a given set of params.
The Action ID is returned for use with 'juju show-action-output
Params are validated according to the charm for the unit's application. The
valid params can be seen using "juju actions
Params may be in a yaml file which is passed with the --params flag, or they may be specified by a key.key.key...=value format (see examples below.) Params given in the CLI invocation will be parsed as YAML unless the --string-args flag is set. This can be helpful for values such as 'y', which is a boolean true in YAML.
If --params is passed, along with key.key...=value explicit arguments, the explicit arguments will override the parameter file.

The
Options specific to scp can be provided after a "--". Refer to the scp(1) man page for an explanation of those options. The "-r" option to recursively copy a directory is particularly useful.
The SSH host keys of the target are verified. The --no-host-key-checks option can be used to disable these checks. Use of this option is not recommended as it opens up the possibility of a man-in-the-middle attack.
Examples:
Copy file /var/log/syslog from machine 2 to the client's current working directory:
juju scp 2:/var/log/syslog .
Recursively copy the /var/log/mongodb directory from a mongodb unit to the client's local remote-logs directory:
juju scp -- -r mongodb/0:/var/log/mongodb/ remote-logs
Copy foo.txt from the client's current working directory to an apache2 unit of model "prod". Proxy the SSH connection through the controller and turn on scp compression:
juju scp -m prod --proxy -- -C foo.txt apache2/1:
Copy multiple files from the client's current working directory to machine 2: juju scp file1 file2 2:
Copy multiple files from the bob user account on machine 3 to the client's current working directory:

Show the results returned by an action with the given ID. A partial ID may also be used. To block until the result is known completed or failed, use the --wait flag with a duration, as in --wait 5s or --wait 1h. Use --wait 0 to wait indefinitely. If units are left off, seconds are assumed.
The default behavior without --wait is to immediately check and return; if the results are "pending" then only the available information will be displayed. This is also the behavior when any negative time is given.

The optional command is executed on the remote machine, and any output is sent back to the user. If no command is specified, then an interactive shell session will be initiated.
When "juju ssh" is executed without a terminal attached, e.g. when piping the output of another command into it, then the default behavior is to not allocate a pseudo-terminal (pty) for the ssh session; otherwise a pty is allocated. This behavior can be overridden by explicitly specifying the behavior with "--pty=true" or "--pty=false".
The SSH host keys of the target are verified. The --no-host-key-checks option can be used to disable these checks. Use of this option is not recommended as it opens up the possibility of a man-in-the-middle attack.
The default identity known to Juju and used by this command is ~/.ssh/id_rsa Options can be passed to the local OpenSSH client (ssh) on platforms where it is available. This is done by inserting them between the target and a possible remote command. Refer to the ssh man page for an explanation of those options.
Examples:
Connect to machine 0:
juju ssh 0
Connect to machine 1 and run command 'uname -a':
juju ssh 1 uname -a
Connect to a mysql unit:
juju ssh mysql/0
Connect to a jenkins unit as user jenkins:

Do not use web browser for authentication
-c, --controller (= "")
Controller to operate in
--credential (= "")
Name of credential to update
Details:
Cloud credentials for controller are used for model operations and manipulations. Since it is common to have long-running models, it is also common to have these cloud credentials become invalid during models' lifetime.
When this happens, a user must update the cloud credential that a model was created with to the new and valid details on controller.
This command allows to update an existing, already-stored, named, cloud-specific controller credential.
NOTE:
This is the only command that will allow you to manipulate cloud
credential for a controller.
All other credential related commands, such as
add-credential, remove-credential and credentials
deal with credentials stored locally on the client not on the controller.
Examples:
juju update-credential aws mysecrets

Update even if the series is not supported by the charm and/or related subordinate charms.
-m, --model (= "")
Model to operate in. Accepts [<controller name>:]<model name>
Details:
When no flags are set, an application or machines series value with be updated within juju.
The update is disallowed unless the --force flag is used if the requested series is not explicitly supported by the application's charm and all subordinates, as well as any other charms which may be deployed to the same machine.
In the case of updating a machine's series, the --force option should be used with caution since using a charm on a machine running an unsupported series may cause unexpected behavior. Alternately, if the requested series supported in later revisions of the charm, upgrade-charm can run beforehand.
Examples:
juju update-series

--resource (= )
Resource to be uploaded to the controller
--revision (= -1)
Explicit revision of current charm
--storage (= )

--switch (= "")
Crossgrade to a different charm
Details:
When no flags are set, the application's charm will be upgraded to the latest revision available in the repository from which it was originally deployed. An explicit revision can be chosen with the --revision flag.
A path will need to be supplied to allow an updated copy of the charm to be located.
Deploying from a path is intended to suit the workflow of a charm author working on a single client machine; use of this deployment method from multiple clients is not supported and may lead to confusing behaviour. Each local charm gets uploaded with the revision specified in the charm, if possible, otherwise it gets a unique revision (highest in state + 1).
When deploying from a path, the --path flag is used to specify the location from which to load the updated charm. Note that the directory containing the charm must match what was originally used to deploy the charm as a superficial check that the updated charm is compatible.
Resources may be uploaded at upgrade time by specifying the --resource flag. Following the resource flag should be name=filepath pair. This flag may be repeated more than once to upload more than one resource.
juju upgrade-charm foo --resource bar=/some/file.tgz --resource baz=./docs/cfg.xml
Where bar and baz are resources named in the metadata for the foo charm. Storage constraints may be added or updated at upgrade time by specifying the --storage flag, with the same format as specified in "juju deploy". If new required storage is added by the new charm revision, then you must specify constraints or the defaults will be applied.
juju upgrade-charm foo --storage cache=ssd,10G
Charm settings may be added or updated at upgrade time by specifying the --config flag, pointing to a YAML-encoded application config file.
juju upgrade-charm foo --config config.yaml
If the new version of a charm does not explicitly support the application's series, the upgrade is disallowed unless the --force-series flag is used. This option should be used with caution since using a charm on a machine running an unsupported series may cause unexpected behavior.
The --switch flag allows you to replace the charm with an entirely different one. The new charm's URL and revision are inferred as they would be when running a deploy command.
Please note that --switch is dangerous, because juju only has limited information with which to determine compatibility; the operation will succeed, regardless of potential havoc, so long as the following conditions hold: - The new charm must declare all relations that the application is currently participating in.
- All config settings shared by the old and new charms must have the same types.
The new charm may add new relations and configuration settings.
--switch and --path are mutually exclusive.
--path and --revision are mutually exclusive. The revision of the updated charm is determined by the contents of the charm at the specified path.
--switch and --revision are mutually exclusive. To specify a given revision number with --switch, give it in the charm URL, for instance "cs:wordpress-5" would specify revision number 5 of the wordpress charm.
Use of the --force-units flag is not generally recommended; units upgraded while in an error state will not have upgrade-charm hooks executed, and may cause unexpected behavior.

Details:
Juju provides agent software to every machine it creates. This command upgrades that software across an entire model, which is, by default, the current model.
A model's agent version can be shown with juju model-config agent-
version.
A version is denoted by: major.minor.patch The upgrade candidate will be auto-selected if '--agent-version' is not specified:
- If the server major version matches the client major version, the
version selected is minor+1. If such a minor version is not available then
the next patch version is chosen.
- If the server major version does not match the client major version,
the version selected is that of the client version.
If the controller is without internet access, the client must first supply
the software to the controller's cache via the juju sync-agent-binaries command.
The command will abort if an upgrade is in progress. It will also abort if
a previous upgrade was not fully completed (e.g.: if one of the
controllers in a high availability model failed to upgrade).
If a failed upgrade has been resolved, '--reset-previous-upgrade' can be used to allow the upgrade to proceed.
Backups are recommended prior to upgrading.
Examples:
juju upgrade-juju --dry-run
juju upgrade-juju --agent-version 2.0.1
