First off, I may not have thanked you yet for this amazing role. I'm using it for almost all my infrastructure. Thank you!

Wanted to open an issue for better visibility.

c5836ad is a breaking change for the command option. Might it be better to do something along these lines?

{% if container.command is defined %}
{% if container.command is string %}
    command: {{ container.command }}
{% else %}
    command:
{% for command in container.command %}
      - {{ command }}
{% endfor %}
{% endif %}
{% endif %}

I'd still like to see arrays neatly generated in my docker-compose file, as I use this to pass options to Traefik. Maybe I should be using a separate file rather than my host_vars monolith, but that's a different issue :)

Is there a functional difference in docker-compose that I'm missing? I defer to your expertise. I'd be happy to submit a PR if you're in agreement.

When passing environment vars in the format of:

environment:
  TZ: Europe/London

the output in the docker-compose appears as

environment:
  - TZ

When passed in the older format of:

environment:
  - 'TZ=Europe/London'

The correct vars are created

The initial task to check the destination passes, but I receive the following error when Ansible tries to generate a docker compose file.

TASK [ironicbadger.docker_compose_generator : write docker-compose file] ******************** An exception occurred during task execution. To see the full traceback, use -vvv. The error was: ansible.errors.AnsibleUndefinedVariable: 'containers' is undefined. 'containers' is undefined fatal: [192.168.110.10]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'containers' is undefined. 'containers' is undefined"}

I am not sure why Ansible says containers is undefined. I double checked the syntax and indentation, which look okay. I used your example to A/B test and receive the same error.

I can send my playbook yaml and requirements yaml if that will be helpful.

Ansible: 2.14.4
Docker on remote host: 26.0.2
Docker compose on remote host: 2.26.1

I tried to have 2 dashes but it doesn't work, something like:
command: --nocacerts

Good day!
Thank you very much for this role, I have noticed a small problem though.
When I try to specify a logging configuration for a container, it never shows up in the output. Now, this very much could be a problem with my syntax and such, but I see no errors being thrown and everything else gets generated appropriately into the resulting Compose file.
Digging thru the template file, I can see where the loop exists to handle the logging settings, but they never trigger.

Example:

• service_name: authelia
  container_name: authelia
  hostname: authelia
  image: authelia/authelia:4.32.2
  active: true
  volumes:
  • "{{ appdata_path }}/authelia:/config"
    restart: always
    include_global_env_vars: true
    logging:
    driver: "json-file"
    options:
    max-size: "200k"
    max-file: "10"
