Ansible subordinate charm executes preconfigured ansible playbook to handle minor details that are out of scope of superior charm.
See the example in bundles directory.
Simple way to deploy playbook as a charm:
juju deploy huntdatacenter-ansible "${app_name}" --config [email protected]
juju integrate "${app_name}:juju-info" "${superior_app}:juju-info"
Playbook should use tags matching charm hooks:
installstart(called after installation - start hook)stop(called before removal - stop hook)config(called after config changes - config-changed hook)
See config.yaml.
juju config "${app_name}"
See actions.yaml.
juju list-actions "${app_name}"
Test adding storage
size=2G
juju add-storage "${unit_name}" "data=${size}"
