If an image is not found or pull is true, the image will be pulled from the registry. If no tag is included, C(latest) will be used. - Can also be an image ID.

You need to explicitly use I(purge_networks) to enforce the removal of the default network (and all other networks not explicitly mentioned in I(networks)). Alternatively, use the I(networks_cli_compatible) option, which will be enabled by default from Ansible 2.12 on. elements: dict suboptions: aliases: description: - List of aliases for this container in this network.

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.

When the container is created by this module, its C(StopTimeout) configuration will be set to this value. - When the container is stopped, will be used as a timeout for stopping the container.

If two ranges with different lengths are specified, the shorter range will be used. Since Ansible 2.10, 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 *not* allowed. This is different from the C(docker) command line utility. Use the L(dig lookup,../lookup/dig.html) to resolve hostnames. - A value of C(all) will publish all exposed container ports to random host ports, ignoring any other mappings. - If I(networks) parameter is provided, will inspect each network to see if there exists a bridge network with optional parameter C(com.docker.network.bridge.host_binding_ipv4). If such a network is found, then published ports where no host IP address is specified will be bound to the host IP pointed to by C(com.docker.network.bridge.host_binding_ipv4). Note that the first bridge network with a C(com.docker.network.bridge.host_binding_ipv4) value encountered in the list of I(networks) is the one that will be used. elements: str type: list restart_retries: description: - Use with restart policy to control maximum number of restart attempts. type: int device_read_iops: description: - List of device and read rate (IO per second) from device. elements: dict suboptions: path: description: - Device path in the container. required: true type: str rate: description: - Device read limit. - Must be a positive integer. required: true type: int type: list device_write_bps: description: - List of device and write rate (bytes per second) to device. elements: dict suboptions: path: description: - Device path in the container. required: true type: str rate: description: - Device read limit in format C(<number>[<unit>]). - Number is a positive integer.

Removal usually is very fast, but it can happen that during high I/O load, removal can take longer. By default, the module will wait until the container has been removed before trying to (re-)create it, however long this takes. - By setting this option, the module will wait at most this many seconds for the container to be removed. If the container is still in the removal phase after this many seconds, the module will fail. type: float version_added: 0.2.0 version_added_collection: community.general networks_cli_compatible: description: - 'When networks are provided to the module via the I(networks) option, the module behaves differently than C(docker run --network): C(docker run --network other) will create a container with network C(other) attached, but the default network not attached. This module with I(networks: {name: other}) will create a container with both C(default) and C(other) attached. If I(purge_networks) is set to C(yes), the C(default) network will be removed afterwards.' - If I(networks_cli_compatible) is set to C(yes), this module will behave as C(docker run --network) and will *not* add the default network if I(networks) is specified. If I(networks) is not specified, the default network will be attached. - '*Note* that docker CLI also sets I(network_mode) to the name of the first network added if C(--network) is specified. For more compatibility with docker CLI, you explicitly have to set I(network_mode) to the name of the first network you''re adding. This behavior will change for Ansible 2.14: then I(network_mode) will automatically be set to the first network name in I(networks) if I(network_mode) is not specified, I(networks) has at least one entry and I(networks_cli_compatible) is C(true).' - Current value is C(no).

This causes problems with containers which use different values for these options. - The default value is C(compatibility), which will ensure that the default values are used when the values are not explicitly specified by the user. - From Ansible 2.14 on, the default value will switch to C(no_defaults). To avoid deprecation warnings, please set I(container_default_behavior) to an explicit value. - 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 version_added: 0.2.0 version_added_collection: community.general

For compatibility reasons, the facts are also accessible directly as C(docker_container).
