all this is based on a German computer magazine:
c’t 2024, Heft 1 …

using community.docker.docker_compose with:

- name: "{{ docker_compose_params.command }}: docker compose '{{ service_cfg.name }}/docker-compose.yml'"
  community.docker.docker_compose:
    project_name: "{{ service_cfg.name }}"
    project_src: "{{ service_cfg.directory }}"
    state: "{{ docker_compose_params.state }}"
    restarted: "{{ docker_compose_params.restarted }}"
    stopped: "{{ docker_compose_params.stopped }}"
    recreate: "{{ docker_compose_params.recreate }}"
    remove_orphans: "{{ docker_compose_params.remove_orphans }}"
    remove_volumes: "{{ docker_compose_params.remove_volumes }}"
  register: service_stack
  tags: [ always ]

I always get the following error:
fatal: [192.168.178.51]: FAILED! => {"changed": false, "msg": "Unable to load docker-compose. Trypip install docker-compose. Error: Traceback (most recent call last):\n File \"/tmp/ansible_community.docker.docker_compose_payload_4k9kgich/ansible_community.docker.docker_compose_payload.zip/ansible_collections/community/docker/plugins/modules/docker_compose.py\", line 522, in <module>\nModuleNotFoundError: No module named 'compose'\n"}

I have checked and tried many things but nothing gave me a hint.

This is an info starting the playbook with -vvv
<192.168.178.51> (1, b'\r\n{"failed": true, "msg": "Unable to load docker-compose. Try pip install docker-compose.

This happens independently of the docker-compse.yml I wish to create: watchtower, traefik …

It looks to me that you have docker compose and you are using the module for docker-compose when you should be using the new docker compose module.

Alternatively, you can read the error message, particularly the pip install docker-compose part, which does give you a hint what you could do :wink:

But I agree with @chris, better use the new docker_compose_v2 module and don’t start caring about the docker-compose v1 Python package…
