GitLab CI Runner, how to use volumes or mounts in service containers

问题

I use GitLab CI Runner, it uses the command:

docker run -d --name postgres postgres:9.4

I want to do something like this:

docker run -d --name postgres --volumes-from postgres_datastore postgres:9.4

But GitLab CI Runner doesn't support any options (-v or --volumes-from).

Is there any other way?

回答1:

The Docker volumes-from option is not yet available in Gitlab CI Runner (see this PR), however you can configure host mounts and volumes:

[runners.docker]
  volumes = ["/host/path:/target/path:rw", "/some/path"]

The above example would mount /host/path at /target/path/ inside the container and also create a new volume container at /some/path.

See the Gitlab CI Runner manual for all docker related options.

Edit:

For service containers it seems you can only define volumes via the dockerfile of the service image. Maybe enough depending on your requirements.
