Overview

POL for Juju CAAS

Testing

The tests of this charm are done using tox and Zaza.

Prepare environment

The machine in which the tests are run needs access to a juju k8s controller. The easiest way to approach this is by executing the following commands:

sudo apt install tox -y
sudo snap install microk8s --classic
sudo snap install juju

microk8s.status --wait-ready
microk8s.enable storage dashboard dns

juju bootstrap microk8s k8s-cloud

If /usr/bin/python does not exist, you should probably need to do this:

sudo ln -s /usr/bin/python3 /usr/bin/python
