This is not needed, as ansible is build-in in the ubuntu GitHub Runners. I'll not follow this idea further.

This action is based on alpine:3 image.
You can execute all Ansible related actions i.e, ansible or ansible-playbook.
You can also execute standard Linux commands as base Docker image is ubuntu.

Required Command to execute. Default "ansible-playbook".

  command: "ansible-playbook main.yml"

This is heavily inspired and copied from https://github.com/RvuvuzelaM/ansible-cli-github-action with some build optimisations.
