Dear Experts and Community,  
I have the following problem. I pull a ES image from Docker Hub, then I configure it to bind ports to host: 9200,9300. I add the following env var:  
`cluster.initial_master_nodes = elasticsearch`  
And then I deploy the container. It runs okay, however I know it probably runs in normal mode, so it is ready to be clustered any time.  
And I want it to run in single node mode, however if I add a single\_node variable to Env it logs that there is no such option...

Thanks to anybody who will be willing to help or even give me a clue on that matter.  
Greetings,  
Łukasz
