Continuous deployment, upgrade and testing for Juju.

Project description


Build Status Documentation Status PyPI - Python Version

Continuous deployment, upgrade and testing for Juju.

At HUNT Cloud we run our scientific services based on OpenStack orchestrated by Juju. Such cloud deployments rely on a large set of collaborative softwares, and upgrades can sometimes cause considerable pain. We have therefore introduced Jujuna - a tool to simplify the validation of Juju-based OpenStack upgrades.

New to Juju? Juju is a cool controller and agent based tool from Canonical to easily deploy and manage applications (called Charms) on different clouds and environments (see how it works for more details).


Easy to install using:

pip3 install jujuna

May require installation of libssl-dev package or equivalent if not present in the system.

Run command jujuna --help to get the help menu. You can also check the usage in the documentation.


Running Jujuna requires a working deployment of Juju controller. Juju configs ~/.local/share/juju/ have to be present or credentials have to be specified using params.

# Deploy Ceph bundle into ceph model
jujuna deploy openstack/bundle.yaml -m test-cloud -w

# Upgrade apps in ceph model_name
jujuna upgrade -m test-cloud

# Test apps in the model after upgrade
jujuna test tests/openstack-ocata.yaml -t 1800 -m test-cloud

# Destroy apps within a model, without destroying the model
jujuna clean -m test-cloud -w -f -t 1800

If you don't have any bundle or just need to try jujuna with some simple example, you can follow our example guide.

Testing Jujuna

How to make sure jujuna and your feature works before pushing out new version.

Testing jujuna with python environments:

tox -e lint
tox -e py35
tox -e py36
tox -e py37

Testing specific feature:

py.test -k test_feature

Deploy to docker registry:
