As a result, this image does not support clustering out of the box and extra configuration must be set in order to support it.
Supporting clustering imply having Elasticsearch in a production mode which is more strict about the bootstrap checks that it performs, especially when checking the value of `vm.max_map_count` which is not namespaced and thus must be set to an acceptable value on the host (as opposed to simply using `--sysctl` on `docker run`).

One example of adding clustering support is to pass the configuration on the `docker run`:
```console
$ docker run -d --name elas elasticsearch -Etransport.host=0.0.0.0 -Ediscovery.zen.minimum_master_nodes=1
```
