Issue

• I would like to configure CJE to pull cje-oc and cje-mm images from a private registry. Thus, for example, docker pull cloudbees/cje-mm:2.60.3.1 it actually pulls my-docker-mirror-host/cloudbees/cje-mm:2.60.3.1.

```md
docker_options = --log-driver=syslog --registry-mirror=http://<my-docker-mirror-host>
```

2) Execute cje prepare worker-restart

Then, go to `config` and add each of the worker names (separated by comma).

```md
[server]

## The name of the servers to restart

names = worker-1,worker-2,...,worker-N
```

3) cje apply
