    container:
      enabled: false
  tasks:
    - name: Set task host to 'localhost'
      ansible.builtin.set_fact:
        task_host: localhost
      when: not container.enabled

    - name: Set 'base_dir'
      ansible.builtin.set_fact:
        base_dir: "{{ container.enabled | ternary('/home/user/project/', '') }}"

    - name: List files
      delegate_to: "{{ task_host }}"
