Run Ansible on Fedora CoreOS (Without rpm-ostree reboot!)

fedora-coreos-ansible.yaml

  become: true
  # We may not have python3 on FCOS, so don't gather facts yet. We will make
  # sure Python is installed first then explicitly gather facts later.
  gather_facts: false
  pre_tasks:
    # If the host doesn't have python3 + the docker and selinux modules,
    # this will fail. failed_when swallows the error but we can later use
    # the return code to decide to try installing these dependencies.
    - name: check ansible dependencies
      raw: python3 -c 'import docker;import selinux' # docker module isn't necessary but useful
      register: __fcos_python3_test

    # ... now define your tasks ...
