Hello guys,

I'm new with elastic and i'm trying to bring up an environment using Elastic and Docker to set up a Graylog Server, but when i try to pass the name of my cluster i got stuck:

**[root@notebook docker]# docker run -d --name=elastic 08794661d6b0 -e "cluster.name=graylog"**  
2a011103b6b71304ee5f960e5d7165032c08e8684ff6bc51ed001bb38efef728  
docker: Error response from daemon: oci runtime error: container\_linux.go:247: starting container process caused "exec: "-e": executable file not found in $PATH".

(The image 08794661d6b0 is [docker.elastic.co/elasticsearch/elasticsearch](http://docker.elastic.co/elasticsearch/elasticsearch) 5.4.0)

Any help it will be appreciate!

Thanks!

```
$ docker run --help

Usage:	docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

```

The option needs to be passed before the image. In your example it assumes `-e` is the command. Try `docker run -d --name=elastic -e "cluster.name=graylog" 08794661d6b0` 🙂

Hello again guys,

I'm run another container:

**[root@notebook docker]# docker run -it --name=elastic -e "cluster.name=graylog" 08794661d6b0 /bin/bash**

and i went to check the elasticsearch.yml and i got this:

\*\*[elasticsearch@e5710541152b config]$ cat elasticsearch.yml \*\*  
**[cluster.name](http://cluster.name): "docker-cluster"**

Is it normal? What am i doing wrong??

Thanks again!

Yeah, that's the default setting from [https://github.com/elastic/elasticsearch-docker/blob/master/build/elasticsearch/elasticsearch.yml#L1](https://github.com/elastic/elasticsearch-docker/blob/master/build/elasticsearch/elasticsearch.yml#L1)

But with your environment variable you are correctly overriding it — mentioned in the docs as well: [https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html#\_a\_present\_the\_parameters\_via\_docker\_environment\_variables](https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html#_a_present_the_parameters_via_docker_environment_variables)

Check the cluster name with curl against localhost:9200/
