Synopsis 

Uses Docker Compose to start, shutdown and scale services. This module requires docker-compose < 2.0.0.
Configuration can be read from a docker-compose.yml or docker-compose.yaml file or inline using the definition option.
See the examples for more details.
Supports check mode.
This module was called docker_service before Ansible 2.8. The usage did not change.

Requirements 

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

Docker API >= 1.20
Docker SDK for Python: Please note that the docker-py Python module has been superseded by docker (see here for details). For Python 2.6, docker-py must be used. Otherwise, it is recommended to install the docker Python module. Note that both modules should not be installed at the same time. Also note that when both modules are installed and one of them is uninstalled, the other might no longer function and a reinstall of it is required.
Docker SDK for Python >= 1.8.0 (use docker-py for Python 2.6)
PyYAML >= 3.11
docker-compose >= 1.7.0, < 2.0.0

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 Docker SDK for Python 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 boolean	Use with state `present` to always build images prior to starting the application. Same as running `docker-compose build` with the pull option. Images will only be rebuilt if Docker detects a change in the Dockerfile or build directory contents. Use the nocache option to ignore the image cache when performing the build. If an existing image is replaced, services using the image will be recreated unless recreate is `never`. Choices: no ← (default) yes
ca_cert aliases: 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.
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.
debug boolean	Debug mode Choices: no ← (default) yes
definition dictionary	Compose file describing one or more services, networks and volumes. Mutually exclusive with project_src and files.
dependencies boolean	When state is `present` specify whether or not to include linked services. Choices: no yes ← (default)
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_file path added in 1.9.0 of community.docker	By default environment files are loaded from a `.env` file located directly under the project_src directory. env_file can be used to specify the path of a custom environment file instead. The path is relative to the project_src directory. Requires `docker-compose` version 1.25.0 or greater. Note: `docker-compose` versions `<=1.28` load the env file from the current working directory of the `docker-compose` command rather than project_src.
files list / elements=path	List of Compose file names relative to project_src. Overrides `docker-compose.yml` or `docker-compose.yaml`. Files are loaded and merged in the order given.
hostname_check boolean	Whether or not to check the Docker daemon’s hostname against the name provided in the client certificate. Choices: no ← (default) yes
nocache boolean	Use with the build option to ignore the cache during the image build process. Choices: no ← (default) yes
profiles list / elements=string added in 1.8.0 of community.docker	List of profiles to enable when starting services. Equivalent to `docker-compose --profile`. Requires `docker-compose` version 1.28.0 or greater.
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 `docker-compose.yml` or `docker-compose.yaml` file. Mutually exclusive with definition. Required when no definition is provided.
pull boolean	Use with state `present` to always pull images prior to starting the application. Same as running `docker-compose pull`. When a new image is pulled, services using the image will be recreated unless recreate is `never`. Choices: no ← (default) yes
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 smart ← (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: no ← (default) yes
remove_volumes boolean	Use with state `absent` to remove data volumes. Choices: no ← (default) yes
restarted boolean	Use with state `present` to restart all containers defined in the Compose file. If services is defined, only the containers listed there will be restarted. Choices: no ← (default) yes
scale dictionary	When state is `present` scale services. 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	When state is `present` run `docker-compose up` resp. `docker-compose stop` (with stopped) resp. `docker-compose restart` (with restarted) on a subset of services. If empty, which is the default, the operation will be performed on all services defined in the Compose file (or inline definition).
ssl_version string	Provide a valid SSL version number. Default value determined by ssl.py module. If the value is not specified in the task, the value of environment variable `DOCKER_SSL_VERSION` will be used instead.
state string	Desired state of the project. Specifying `present` is the same as running `docker-compose up` resp. `docker-compose stop` (with stopped) resp. `docker-compose restart` (with restarted). Specifying `absent` is the same as running `docker-compose down`. Choices: absent present ← (default)
stopped boolean	Use with state `present` to stop all containers defined in the Compose file. If services is defined, only the containers listed there will be stopped. Requires `docker-compose` version 1.17.0 or greater for full support. For older versions, the services will first be started and then stopped when the service is supposed to be created as stopped. Choices: no ← (default) yes
timeout integer	Timeout in seconds for container shutdown when attached or when containers are already running. Default: 10
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 `yes` 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: no ← (default) yes
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. The current default value is `localhost`. This default is deprecated and will change in community.docker 2.0.0 to be a value computed from docker_host. Explicitly specify `localhost` to make sure this value will still be used, and to disable the deprecation message which will be shown otherwise.
use_ssh_client boolean added in 1.5.0 of community.docker	Currently ignored for this module, but might suddenly be supported later on. Choices: no ← (default) yes
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: no ← (default) yes

Notes 

Note

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_SSL_VERSION, 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.
When connecting to Docker daemon with TLS, you might need to install additional Python packages. For the Docker SDK for Python, version 2.4 or newer, this can be done by installing docker[tls] with ansible.builtin.pip.
Note that the Docker SDK for Python only allows to specify the path to the Docker configuration for very few functions. In general, it will use $HOME/.docker/config.json if the DOCKER_CONFIG environment variable is not specified, and use $DOCKER_CONFIG/config.json otherwise.
This module uses the Docker SDK for Python to communicate with the Docker daemon.
