To install it, use: ansible-galaxy collection install community.docker. You need further requirements to be able to use this module, see Requirements for details.

To use it in a playbook, specify: community.docker.docker_compose_v2.

New in community.docker 3.6.0

Synopsis

• Uses Docker Compose to start or shutdown services.

Requirements

The below requirements are needed on the host that executes this module.

• Docker CLI with Docker compose plugin 2.18.0 or later

• PyYAML if definition is used

Parameters

Parameter	Comments
api_version aliases: docker_api_version string	The version of the Docker API running on the Docker Host. Defaults to the latest version of the API supported by this collection and the docker daemon. If the value is not specified in the task, the value of environment variable DOCKER_API_VERSION will be used instead. If the environment variable is not set, the default value will be used. Default: "auto"
build string	Whether to build images before starting containers. This is used when docker compose up is run. always always builds before starting containers. This is equivalent to the --build option of docker compose up. never never builds before starting containers. This is equivalent to the --no-build option of docker compose up. policy uses the policy as defined in the Compose file. Choices: "always" "never" "policy" ← (default)
ca_path aliases: ca_cert, tls_ca_cert, cacert_path path	Use a CA certificate when performing server verification by providing the path to a CA certificate file. If the value is not specified in the task and the environment variable DOCKER_CERT_PATH is set, the file ca.pem from the directory specified in the environment variable DOCKER_CERT_PATH will be used.
check_files_existing boolean added in community.docker 3.9.0	If set to false, the module will not check whether one of the files compose.yaml, compose.yml, docker-compose.yaml, or docker-compose.yml exists in project_src if files is not provided. This can be useful if environment files with COMPOSE_FILE are used to configure a different filename. The module currently does not check for COMPOSE_FILE in environment files or the current environment. Choices: false true ← (default)
cli_context string	The Docker CLI context to use.
client_cert aliases: tls_client_cert, cert_path path	Path to the client’s TLS certificate file. If the value is not specified in the task and the environment variable DOCKER_CERT_PATH is set, the file cert.pem from the directory specified in the environment variable DOCKER_CERT_PATH will be used.
client_key aliases: tls_client_key, key_path path	Path to the client’s TLS key file. If the value is not specified in the task and the environment variable DOCKER_CERT_PATH is set, the file key.pem from the directory specified in the environment variable DOCKER_CERT_PATH will be used.
definition dictionary added in community.docker 3.9.0	Compose file describing one or more services, networks and volumes. Mutually exclusive with project_src and files. If provided, PyYAML must be available to this module, and project_name must be specified. Note that a temporary directory will be created and deleted afterwards when using this option.
dependencies boolean	When state is present or restarted, specify whether or not to include linked services. Choices: false true ← (default)
docker_cli path	Path to the Docker CLI. If not provided, will search for Docker CLI on the PATH.
docker_host aliases: docker_url string	The URL or Unix socket path used to connect to the Docker API. To connect to a remote host, provide the TCP connection string. For example, tcp://192.0.2.23:2376. If TLS is used to encrypt the connection, the module will automatically replace tcp in the connection URL with https. If the value is not specified in the task, the value of environment variable DOCKER_HOST will be used instead. If the environment variable is not set, the default value will be used. Default: "unix:///var/run/docker.sock"
env_files list / elements=path	By default environment files are loaded from a .env file located directly under the project_src directory. env_files can be used to specify the path of one or multiple custom environment files instead. The path is relative to the project_src directory.
files list / elements=path added in community.docker 3.7.0	List of Compose file names relative to project_src to be used instead of the main Compose file (compose.yml, compose.yaml, docker-compose.yml, or docker-compose.yaml). Files are loaded and merged in the order given. Mutually exclusive with definition.
profiles list / elements=string	List of profiles to enable when starting services. Equivalent to docker compose --profile.
project_name string	Provide a project name. If not provided, the project name is taken from the basename of project_src. Required when definition is provided.
project_src path	Path to a directory containing a Compose file (compose.yml, compose.yaml, docker-compose.yml, or docker-compose.yaml). If files is provided, will look for these files in this directory instead. Mutually exclusive with definition.
pull string	Whether to pull images before running. This is used when docker compose up is run. always ensures that the images are always pulled, even when already present on the Docker daemon. missing only pulls them when they are not present on the Docker daemon. never never pulls images. If they are not present, the module will fail when trying to create the containers that need them. policy use the Compose file’s pull_policy defined for the service to figure out what to do. Choices: "always" "missing" "never" "policy" ← (default)
recreate string	By default containers will be recreated when their configuration differs from the service definition. Setting to never ignores configuration differences and leaves existing containers unchanged. Setting to always forces recreation of all existing containers. Choices: "always" "never" "auto" ← (default)
remove_images string	Use with state=absent to remove all images or only local images. Choices: "all" "local"
remove_orphans boolean	Remove containers for services not defined in the Compose file. Choices: false ← (default) true
remove_volumes boolean	Use with state=absent to remove data volumes. Choices: false ← (default) true
scale dictionary added in community.docker 3.7.0	Define how to scale services when running docker compose up. Provide a dictionary of key/value pairs where the key is the name of the service and the value is an integer count for the number of containers.
services list / elements=string	Specifies a subset of services to be targeted.
state string	Desired state of the project. present is equivalent to running docker compose up. stopped is equivalent to running docker compose stop. absent is equivalent to running docker compose down. restarted is equivalent to running docker compose restart. Choices: "absent" "stopped" "restarted" "present" ← (default)
timeout integer	Timeout in seconds for container shutdown when attached or when containers are already running.
tls boolean	Secure the connection to the API by using TLS without verifying the authenticity of the Docker host server. Note that if validate_certs is set to true as well, it will take precedence. If the value is not specified in the task, the value of environment variable DOCKER_TLS will be used instead. If the environment variable is not set, the default value will be used. Choices: false ← (default) true
tls_hostname string	When verifying the authenticity of the Docker Host server, provide the expected name of the server. If the value is not specified in the task, the value of environment variable DOCKER_TLS_HOSTNAME will be used instead. If the environment variable is not set, the default value will be used.
validate_certs aliases: tls_verify boolean	Secure the connection to the API by using TLS and verifying the authenticity of the Docker host server. If the value is not specified in the task, the value of environment variable DOCKER_TLS_VERIFY will be used instead. If the environment variable is not set, the default value will be used. Choices: false ← (default) true
wait boolean added in community.docker 3.8.0	When running docker compose up, pass --wait to wait for services to be running/healthy. A timeout can be set with the wait_timeout option. Choices: false ← (default) true
wait_timeout integer added in community.docker 3.8.0	When wait=true, wait at most this amount of seconds.

Attributes

Attribute	Support	Description
action_group	Action groups: community.docker.docker, docker	Use group/docker or group/community.docker.docker in module_defaults to set defaults for this module.
check_mode	Support: full In check mode, pulling the image does not result in a changed result.	Can run in check_mode and return changed status prediction without modifying target.
diff_mode	Support: none	Will return details on what has changed (or possibly needs changing in check_mode), when in diff mode.

Notes

Note

• The Docker compose CLI plugin has no stable output format (see for example https://github.com/docker/compose/issues/10872), and for the main operations also no machine friendly output format. The module tries to accomodate this with various version-dependent behavior adjustments and with testing older and newer versions of the Docker compose CLI plugin.

  Currently the module is tested with multiple plugin versions between 2.18.1 and 2.23.3. The exact list of plugin versions will change over time. New releases of the Docker compose CLI plugin can break this module at any time.

• Connect to the Docker daemon by providing parameters with each task or by defining environment variables. You can define DOCKER_HOST, DOCKER_TLS_HOSTNAME, DOCKER_API_VERSION, DOCKER_CERT_PATH, DOCKER_TLS, DOCKER_TLS_VERIFY and DOCKER_TIMEOUT. If you are using docker machine, run the script shipped with the product that sets up the environment. It will set these variables for you. See https://docs.docker.com/machine/reference/env/ for more details.

• This module does not use the Docker SDK for Python to communicate with the Docker daemon. It directly calls the Docker CLI program.
