module: docker_container

short_description: manage Docker containers

description:
  - Manage the life cycle of Docker containers.
  - Supports check mode. Run with C(--check) and C(--diff) to view config difference and list of actions to be taken.

notes:
  - For most config changes, the container needs to be recreated. This means that the existing container has to be destroyed and
    a new one created. This can cause unexpected data loss and downtime. You can use the I(comparisons) option to
    prevent this.
  - If the module needs to recreate the container, it will only use the options provided to the module to create the
    new container (except I(image)). Therefore, always specify B(all) options relevant to the container.
  - When I(restart) is set to C(true), the module will only restart the container if no config changes are detected.

    support: partial
    details:
      - When trying to pull an image, the module assumes this is always changed in check mode.

    support: full

options:
  auto_remove:
    description:
      - Enable auto-removal of the container on daemon side when the container's process exits.
      - If I(container_default_behavior) is set to C(compatibility), this option has a default of C(false).
    type: bool
  blkio_weight:
    description:
      - Block IO (relative weight), between 10 and 1000.
    type: int
  capabilities:
    description:
      - List of capabilities to add to the container.
      - This is equivalent to C(docker run --cap-add), or the docker-compose option C(cap_add).

  cgroupns_mode:
    description:
      - Specify the cgroup namespace mode for the container.
      - The Docker CLI calls this simply C(cgroupns).
    type: str
    choices:
      - host
      - private
    version_added: 3.0.0
  cgroup_parent:
    description:
      - Specify the parent cgroup for the container.
    type: str
    version_added: 1.1.0
  cleanup:
    description:
      - Use with I(detach=false) to remove the container after successful execution.
    type: bool
    default: false
  command:
    description:
      - Command to execute when the container starts. A command may be either a string or a list.
      - Prior to version 2.4, strings were split on commas.
      - See I(command_handling) for differences in how strings and lists are handled.
    type: raw
  comparisons:
    description:
      - Allows to specify how properties of existing containers are compared with
        module options to decide whether the container should be recreated / updated
        or not.
      - Only options which correspond to the state of a container as handled by the
        Docker daemon can be specified, as well as I(networks).
      - Must be a dictionary specifying for an option one of the keys C(strict), C(ignore)
        and C(allow_more_present).
      - If C(strict) is specified, values are tested for equality, and changes always
        result in updating or restarting. If C(ignore) is specified, changes are ignored.
      - C(allow_more_present) is allowed only for lists, sets and dicts. If it is
        specified for lists or sets, the container will only be updated or restarted if
        the module option contains a value which is not present in the container's
        options. If the option is specified for a dict, the container will only be updated
        or restarted if the module option contains a key which is not present in the
        container's option, or if the value of a key present differs.
      - The wildcard option C(*) can be used to set one of the default values C(strict)
        or C(ignore) to I(all) comparisons which are not explicitly set to other values.
      - See the examples for details.
    type: dict
  container_default_behavior:
    description:
      - In older versions of this module, various module options used to have default values.
        This caused problems with containers which use different values for these options.
      - The default value is now C(no_defaults). To restore the old behavior, set it to
        C(compatibility), which will ensure that the default values are used when the values
        are not explicitly specified by the user.
      - This affects the I(auto_remove), I(detach), I(init), I(interactive), I(memory),
        I(paused), I(privileged), I(read_only) and I(tty) options.
    type: str
    choices:
      - compatibility
      - no_defaults
    default: no_defaults
  command_handling:
    description:
      - The default behavior for I(command) (when provided as a list) and I(entrypoint) is to
        convert them to strings without considering shell quoting rules. (For comparing idempotency,
        the resulting string is split considering shell quoting rules.)
      - Also, setting I(command) to an empty list of string, and setting I(entrypoint) to an empty
        list will be handled as if these options are not specified. This is different from idempotency
        handling for other container-config related options.
      - When this is set to C(compatibility), which was the default until community.docker 3.0.0, the
        current behavior will be kept.
      - When this is set to C(correct), these options are kept as lists, and an empty value or empty
        list will be handled correctly for idempotency checks. This has been the default since
        community.docker 3.0.0.
    type: str
    choices:
      - compatibility

    description:
      - CPU shares (relative weight).
    type: int
  default_host_ip:
    description:
      - Define the default host IP to use.
      - Must be an empty string, an IPv4 address, or an IPv6 address.
      - With Docker 20.10.2 or newer, this should be set to an empty string (C("")) to avoid the
        port bindings without an explicit IP address to only bind to IPv4.
        See U(https://github.com/ansible-collections/community.docker/issues/70) for details.
      - By default, the module will try to auto-detect this value from the C(bridge) network's
        C(com.docker.network.bridge.host_binding_ipv4) option. If it cannot auto-detect it, it
        will fall back to C(0.0.0.0).

    version_added: 1.2.0
  detach:
    description:
      - Enable detached mode to leave the container running in background.
      - If disabled, the task will reflect the status of the container run (failed if the command failed).

      - Please note that if you are passing values in with Jinja2 templates, like C("{{ value }}"), you need to add C(| string) to prevent Ansible to

      - When I(state) is C(present) or C(started), the module compares the configuration of an existing

      - How to handle labels inherited from the image that are not set explicitly.
      - When C(ignore), labels that are present in the image but not specified in I(labels) will be

      - When C(fail), if there are labels present in the image which are not set from I(labels), the

      - If set to C(recreate) the container will be recreated.
