Mojo: Continuous Delivery for Juju

Mojo is a system of configuration and tools for verifying the success of Juju environment deployments. It's available as an open source project under the GPLv3 license on Launchpad.

To get started with mojo, on trusty, xenial or yakety (using the mojo-how-to spec as an example):

  1. Install Mojo via the snap:

    sudo snap install --classic mojo
    

    Alternatively, Mojo is available via a PPA:

    sudo add-apt-repository ppa:mojo-maintainers/ppa
    sudo apt-get update
    sudo apt-get install mojo
    
  2. Setup Juju and LXD.

    LXD is needed locally for this quick start and it also works well as backing for Juju. The instructions on the Juju getting started page are good ones to follow. When ready setup a model:

    juju add-model mojo-how-to
    
  3. Create a project and export variables to save typing later on:

    export MOJO_SERIES=trusty
    export MOJO_PROJECT=mojo-how-to
    export MOJO_WORKSPACE=$MOJO_PROJECT
    export MOJO_SPEC="lp:~mojo-maintainers/mojo/mojo-specs"
    export MOJO_STAGE=mojo-how-to/devel
    mojo project-new -c lxd $MOJO_PROJECT
    
  4. Create a workspace:

    mojo workspace-new $MOJO_SPEC $MOJO_WORKSPACE
    
  5. Run your mojo spec to configure your environment as specified in the mojo spec:

    mojo run
    

After the mojo run completes you will have a fully deployed Juju model with a machine running this website. You can run juju status to see the deployment and load the machine ip in your web browser to verify. When you are ready you can remove it all with these steps:

    mojo project-destroy $MOJO_PROJECT
    juju destroy-model mojo-how-to
