community.docker.docker_compose_v2_run module – Run command in a new container of a Compose service

Note

This module is part of the community.docker collection (version 3.13.1).

You might already have this collection installed if you are using the ansible package. It is not included in ansible-core. 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_v2_run.

New in community.docker 3.13.0

Synopsis

  • Uses Docker Compose to run a command in a new container for a service.

  • This encapsulates docker compose run.

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"

argv

list / elements=string

The command to execute.

Since this is a list of arguments, no quoting is needed.

argv or command are mutually exclusive.

build

boolean

Build image before starting container.

Note that building can insert information into stdout or stderr.

Choices:

  • false ← (default)

  • true

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.

cap_add

list / elements=string

Linux capabilities to add to the container.

cap_drop

list / elements=string

Linux capabilities to drop from the container.

chdir

string

The directory to run the command in.

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)

cleanup

boolean

Automatically remove th econtainer when it exits.

Corresponds to the --rm option of docker compose run.

Choices:

  • false ← (default)

  • true

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.

command

string

The command to execute.

argv or command are mutually exclusive.

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.

detach

boolean

Whether to run the command synchronously (detach=false, default) or asynchronously (detach=true).

If set to true, stdin cannot be provided, and the return values stdout, stderr, and rc are not returned. Instead, the return value container_id is provided.

Choices:

  • false ← (default)

  • true

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.

entrypoint

string

Override the entrypoint of the container image.

env

dictionary

Dictionary of environment variables with their respective values to be passed to the command ran inside the container.

Values which might be parsed as numbers, booleans or other types by the YAML parser must be quoted (for example "true") in order to avoid data loss.

Please note that if you are passing values in with Jinja2 templates, like "{{ value }}", you need to add | string to prevent Ansible to convert strings such as "true" back to booleans. The correct way is to use "{{ value | string }}".

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.

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.

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.

Choices:

  • false ← (default)

  • true

tls_hostname

string

Notes

Note

  • If you need to evaluate environment variables of the container in command or argv, you need to pass the command through a shell, like command=/bin/sh -c "echo $ENV_VARIABLE".

  • 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.
