Molecule doesn't start systemd

[artis3n]

It has been some time, and this is close to #6 , but given I am not receiving that error I opted for a new issue. I cannot get Molecule working with cgroupsv2 and this container (or most others since the cgroup change, admittedly). This container works fine when executed directly, mirroring the commands in the README, but fails under Molecule during any execution of a systemd task with:

fatal: [instance]: FAILED! => {"changed": false, "msg": "failure 1 during daemon-reload: System has not been booted with systemd as init system (PID 1). Can't operate.\nFailed to connect to bus: Host is down\n"}

This occurs locally on OSX and on an ubuntu 22.04 GitHub Actions runner.

My molecule.yml is:

---
dependency:
  name: galaxy
driver:
  name: docker
platforms:
  - name: instance
    image: geerlingguy/docker-ubuntu2204-ansible:latest
    volumes:
      - /sys/fs/cgroup:/sys/fs/cgroup:rw
    cgroupns_mode: host
    privileged: true
    pre_build_image: true
provisioner:
  name: ansible
verifier:
  name: ansible
scenario:
  name: default
  test_sequence:
#    - dependency
    - destroy
    - syntax
    - create
    - prepare
    - converge
    - idempotence
#    - verify
#    - cleanup
    - destroy

A minimally reproducible converge.yml is:

---
- name: Converge
  hosts: all
  tasks:
    - name: ":("
      become: true
      ansible.builtin.systemd:
        daemon_reload: true

Running molecule test will result in the above error both locally and on the Ubuntu 22.04 runner.

Given the molecule PR introducing cgroupns_mode is merged and I don't see issues about this from others in the molecule and molecule-plugins repos, I am assuming I'm missing something dumb in the molecule.yml. Any thoughts as to what I should be doing to resolve this error?

Hey @artis3n

I managed to fix this by including command: /usr/sbin/init in my molecule.yml:

---
dependency:
  name: galaxy
driver:
  name: podman
platforms:
  - name: instance
    image: docker.io/geerlingguy/docker-ubuntu2204-ansible:latest
    volumes:
      - /sys/fs/cgroup:/sys/fs/cgroup:rw
    cgroupns_mode: host
    command: /usr/sbin/init
    privileged: true
    pre_build_image: true
provisioner:
  name: ansible

(sandbox) ➜  sandbox molecule login  
INFO     Running default > login

Hope this helps 😄 👍🏻

Of course! Thanks. Since this post I broke out what images now use /usr/sbin/init vs. other commands. I will close it. There are a few distros I continue to have issue with, but :shrug: I'll leave them on an ubuntu-20.04 runner. https://github.com/artis3n/ansible-role-tailscale/blob/e217453d8c04c4a0ff1d2528c240f76d135a91d1/.github/workflows/pull_request_target.yml#L57
