.
To check whether it is installed, run ansible-galaxy collection list
.
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
.
DEPRECATED
- Removed in:
version 4.0.0
- Why:
This module uses docker-compose v1, which is End of Life since July 2022.
- Alternative:
Migrate to community.docker.docker_compose_v2
Synopsis
Uses Docker Compose to start, shutdown and scale services. This module requires docker-compose < 2.0.0. Use the community.docker.docker_compose_v2 module for using the modern Docker compose CLI plugin.
Configuration can be read from a
docker-compose.yml
ordocker-compose.yaml
file or inline using thedefinition
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 >= 1.25
Docker SDK for Python: Please note that the docker-py Python module has been superseded by docker (see here for details). 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, < 7. Docker SDK for Python 7+ is incompatible to docker-compose v1.
PyYAML >= 3.11
docker-compose >= 1.7.0, < 2.0.0

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
andDOCKER_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
$HOME/.docker/config.json
if theDOCKER_CONFIG
environment variable is not specified, and use$DOCKER_CONFIG/config.json
otherwise.This module uses the Docker SDK for Python to communicate with the Docker daemon.
