env: description: - Dictionary of key,value pairs. - Values which might be parsed as numbers, booleans or other types by the YAML parser must be quoted (for example V("true")) in order to avoid data loss. - Please note that if you are passing values in with Jinja2 templates, like V("{{ value }}"), you need to add V(| string) to prevent Ansible to convert strings such as V("true") back to booleans. The correct way is to use V("{{ value | string }}"). type: dict tls: default: false description: - Secure the connection to the API by using TLS without verifying the authenticity of the Docker host server.

If two ranges with different lengths are specified, the shorter range will be used. Since community.general 0.2.0, if the source port range has length 1, the port will not be assigned to the first port of the destination range, but to a free port in that range. This is the same behavior as for C(docker) command line utility. - Bind addresses must be either IPv4 or IPv6 addresses. Hostnames are B(not) allowed. This is different from the C(docker) command line utility.

This is different from idempotency handling for other container-config related options. - When this is set to V(compatibility), which was the default until community.docker 3.0.0, the current behavior will be kept. - When this is set to V(correct), these options are kept as lists, and an empty value or empty list will be handled correctly for idempotency checks.
