community.docker.docker connection – Run tasks in docker containers

Note

This connection plugin is part of the community.docker collection (version 2.6.0).

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.

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

Synopsis

  • Run commands or put/fetch files to an existing docker container.

  • Uses the Docker CLI to execute commands in the container. If you prefer to directly connect to the Docker daemon, use the community.docker.docker_api connection plugin.

Hint

Configuration entries for each entry type have a low to high priority order. For example, a variable that is lower in the list will override a variable that is higher up.
