With our long-term goal to simplify TripleO and focus on what people actually deploy and how they operate their clouds, it appears that the Paunch CLI hasn't been a critical piece in our project and I propose that we deprecate it; create an Ansible module to call Paunch as a library only.
I've been playing with it a little today:
Here is how you would call paunch:
- name: Start containers for step {{ step }}
paunch:
config: "/var/lib/tripleo-config/hashed-container-startup-config-step_{{ step }}.json"
config_id: "tripleo_step{{ step }}"
action: apply
container_cli: "{{ container_cli }}"
managed_by: "tripleo-{{ tripleo_role_name }}"
A few benefits:
- Deployment tasks in THT would call the new module instead of a shell command
- More Pythonic and clean for Ansible, to interact with the actual task during the run
- Removing some code in Paunch, make it easier to maintain for us
For now, the Ansible module only covers "paunch apply", we will probably cover "delete" and "cleanup" eventually.
