Installing Juju

Stable versions of Juju are available on Ubuntu, various other Linux distributions, macOS, and Windows. Development releases are also available for testing.

Version 2.5.2

The most recent stable version of Juju is 2.5.2. This is the version we recommend for production use. See the Release Notes.

Ubuntu

Since Ubuntu 14.04 LTS (Trusty) the recommended way to install Juju is with snaps. Nevertheless, the PPA install method is still supported and is mentioned lower down.

On Ubuntu 16.04 LTS (and greater) snapd is installed by default. If you're using Ubuntu 14.04 LTS you will need to install it prior to installing Juju:

sudo apt install snapd

Juju can be installed with the following command:

sudo snap install juju --classic

In the above, the 'stable' snap channel is used by default.

The current version of an installed Juju snap is given by:

snap list juju

And can be updated with:

sudo snap refresh juju

See the Snapcraft documentation for more information on snaps.

Using a PPA

To install the most recent stable version using a PPA:

sudo add-apt-repository -yu ppa:juju/stable
sudo apt install juju

CentOS and other Linuxes

Juju can be installed on various Linux distributions via snaps. On Ubuntu snapd comes pre-installed but if you're running something else you'll need to visit Install snapd to get started.

You can now install Juju with:

sudo snap install juju --classic

For CentOS, download Juju and install it manually: juju-2.5.2-centos7.tar.gz (md5)

macOS

Install Juju on macOS with Homebrew. Simply enter the following into a terminal:

brew install juju

And upgrade Juju with the following:

brew upgrade juju

Windows

For Windows, an installer is available: juju-setup-2.5.2-signed.exe (md5)

Development releases

Development releases (alpha, beta, rc) are regularly published and we encourage users to test these versions with real workloads and use cases. We kindly ask you to file a bug when encountering an issue. Feedback on usability and missing functionality is also very important to us.

Using snaps

See above for how to get started with snaps if you're running a non-Ubuntu Linux distro.

To install a development release using snaps, instead of the 'stable' channel, use the 'beta' channel:

sudo snap install juju --beta --classic

For a cutting edge experience choose the 'edge' channel:

sudo snap install juju --edge --classic

To upgrade or downgrade, use the refresh command with a suitable channel. Below we install 'edge' and then downgrade to 'beta':

sudo snap install juju --edge --classic
sudo snap refresh juju --beta

Using a PPA

To install the development version using a PPA:

sudo add-apt-repository -yu ppa:juju/devel
sudo apt install juju

Installing multiple Juju series

Some environments may see the need to run both the 1.x and the 2.x series of Juju concurrently. See page Running multiple versions of Juju for guidance.

Other platforms

All development release binaries are published on Launchpad. Note that leading edge builds are only available with snaps (via the 'edge' channel).

Juju plugins

Juju functionality can be extended through the use of plugins. See the Juju plugins page for information.

Building from source

Refer to the Contributing documentation in the codebase for instructions on how to build Juju from source.
