A repository to collect initiatives around making the life of a charm author easier.
In the cloud-init directory you will find the following cloud-init scripts to launch reusable VMs to everyday charm development:
charm-dev-juju-3.4.yamlcharm-dev-juju-3.3.yamlcharm-dev-juju-3.2.yamlcharm-dev-juju-3.1.yamlcharm-dev-juju-2.9.yamlcharm-dev-juju-latest-edge.yaml
These script will create a VM with:
- juju (stable
3.4,3.3,3.2,3.1,2.9orlatest-edge) - microk8s 1.29-strict
- ZSH as a default SHELL with oh-my-zsh and juju theme with plugins:
- Pietro's amazing jhack tool.
- Scenario
snapshotcli tool.
Let's say you need to launch a VM using Multipass that runs juju 3.4/stable with:
- 4G RAM
- 3 CPUs
- 30G disk
- and mounting your
reposdirectory inside the ubuntu user home directory
you may run:
multipass launch --cloud-init charm-dev-juju-3.4.yaml \
--timeout 1200 \
--name charm-dev-juju-34 \
--memory 4G \
--cpus 3 \
--disk 30G \
--mount /home/jose/trabajos/canonical/repos:/home/ubuntu/reposOnce the VM is ready you will see:
Launched: charm-dev-juju-34
Mounted '/home/jose/trabajos/canonical/repos' into 'charm-dev-juju-34:/home/ubuntu/repos'
Now you can jump into the new VM:

In the zsh_themes directory you will find a juju.zsh-theme that uses the juju plugin to show a prompt with juju information about controller and model.
