services.consensus.deploy.resources.limits value 'pids' does not match any of the regexes: '^x-'

[karolpivo]

SUMMARY

community.docker.docker_compose module fails to start service when 'deploy.resources.limits.pids' is defined. The same compose service starts when using the 'docker compose' CLI (Docker Compose version v2.16.0).

Please see docker documentation for reference -> https://docs.docker.com/compose/compose-file/deploy/#resources

Relevant docker compose file section:

    deploy:
      resources:
        limits:
          pids: 4096

Ansible error message:
fatal: [instance]: FAILED! => {"changed": false, "msg": "Configuration error - The Compose file 'redacted' is invalid because:\nservices.consensus.deploy.resources.limits value 'pids' does not match any of the regexes: '^x-'"}``

  community.docker.docker_compose:
    project_src: "{{ blockchain_docker_compose_path }}"
    files:
      - dc-execution-{{ clients.execution }}.yml
      - dc-consensus-{{ clients.consensus }}.yml
      - dc-validator-{{ clients.validator }}.yml

ACTUAL RESULTS

This might be because docker-compose 1.x does not support this in Docker Compose definitions. Did you check whether your definition works with the docker-compose 1.x CLI?

[karolpivo]

Thanks for the response. You are right. I'm getting the same error when using docker-compose 1.29.2

Error:
services.consensus.deploy.resources.limits value 'pids' does not match any of the regexes: '^x-'

docker-compose version
docker-compose version 1.29.2, build unknown
docker-py version: <module 'docker.version' from '/usr/local/lib/python3.10/dist-packages/docker/version.py'>
CPython version: 3.10.6
OpenSSL version: OpenSSL 3.0.2 15 Mar 2022

Is there a plan to implement support for 2.x in the Ansible module?

[felixfontein]

That is tracked in #216. There is a WIP PR (#586) but right now there is no ETA when this will be done.

I'll close this issue since I think the question is resolved. If that's not the case please comment so.
