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. Mutually exclusive with `docker_host`.
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`. One of `project_src` and `definition` must be provided. 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. Mutually exclusive with `cli_context`. If neither `docker_host` nor `cli_context` are provided, the value `unix:///var/run/docker.sock` is used.
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`. One of `project_src` and `definition` must be provided.
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.
