The machine needs to be prepared. In CI this is done using molecule/default/prepare.yml:

---
- become: true
  gather_facts: false
  hosts: all
  name: Prepare

    - ansible.builtin.copy:
        content: ok

        owner: root
      name: Place health check
    - ansible.builtin.copy:
        content: Hello world!
        dest: "/index.html"
        group: root
        mode: "0644"
        owner: root

  roles:
    - role: buluma.bootstrap
