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
  post_tasks:
    - ansible.builtin.copy:
        content: ok
        dest: "{{ httpd_data_directory }}/health.html"
        group: root
        mode: "0644"
        owner: root
      name: Place health check
    - ansible.builtin.copy:
        content: Hello world!
        dest: "{{ httpd_data_directory }}/index.html"
        group: root
        mode: "0644"
        owner: root
      name: Place sample page
  roles:
    - role: buluma.bootstrap
    - role: buluma.core_dependencies
    - role: buluma.epel
    - role: buluma.buildtools
    - role: buluma.python_pip
    - openssl_items:
        - common_name: "{{ ansible_fqdn }}"
          name: haproxy
      openssl_key_directory: /tmp
      role: buluma.openssl
    - httpd_port: 8080
      role: buluma.httpd
  vars:
    _httpd_data_directory:
      Alpine: /var/www/localhost/htdocs
      Suse: /srv/www/htdocs
      default: /var/www/html
    ansible_python_interpreter: /usr/bin/python3
    httpd_data_directory:
      "{{ _httpd_data_directory[ansible_os_family] | default(_httpd_data_directory['default']
      ) }}"
