Refer to [Docker Doc](https://docs.docker.com/engine/reference/commandline/run/#volumes-from), the `--volumes-from` flag is used when running or creating a new container and takes the name or ID of the container from which you want to share volumes. Here's the syntax:
```
docker run --volumes-from <container_name_or_id> <image>
```
So put the job container name into the `env` context in this PR.
