This is the original backend used with Woodpecker. The docker backend executes each step inside a separate container started on the agent.
Set to the name of an existing network which will be attached to all your pipeline containers (steps). Please be careful as this allows the containers of different pipelines to access each other!
Enable IPv6 for the networks used by pipeline containers (steps). Make sure you configured your docker daemon to support IPv6.
While the agent was developped with Docker/Moby, Podman can also be used by setting the environment variable
DOCKER_SOCK to point to the podman socket. In order to work without workarounds, Podman 4.0 (or above) is required.
