On executing ansible-playbook -i inventory registry.yml

[DEPRECATION WARNING]: The container_default_behavior option will change its
default value from "compatibility" to "no_defaults" in community.docker 2.0.0. To
remove this warning, please specify an explicit value for it now. This feature
will be removed from community.docker in version 2.0.0. Deprecation warnings can
be disabled by setting deprecation_warnings=False in ansible.cfg.
fatal: [127.0.0.1]: FAILED! => {"changed": false, "msg": "Invalid port: "50001~""}

If I read correctly

- name: Run the Docker Registry container locally.
  docker_container:
    name: registry
    image: '{{ registry_image }}'
    state: started
    published_ports:
      - 5000:5000
    container_default_behavior: compatibility <-- This should fix the warning

However, the new output for (Page 49) docker push localhost:5000/test-image is:

Using default tag: latest
The push refers to repository [localhost:5000/test-image]
Get http://localhost:5000/v2/: read tcp 127.0.0.1:36968->127.0.0.1:5000: read: connection reset by peer

not

The push refers to repository [localhost:5000/test-image]
77cae8ab23bf: Pushed

I have not found help online.

Seems I had a typo of the Port number, 50001 instead of 5000, that accounts for "fatal: [127.0.0.1]: FAILED! => {"changed": false, "msg": "Invalid port: "50001~""}".
However, placing "container_default_behavior: compatibility" under "docker_container:" in both "registry.yml" and "main.yml" removes the DEPRECATION WARNING.
