Trying to setup open - distro elasticsearch cluster in docker swarm and getting error. Used the yaml file given in the link below

> <https://github.com/opendistro/for-elasticsearch-docs/issues/29#>
>
> It would be great to have a little doc on how to deploy a 2 or 3 nodes cluster a…nd maybe even how to make in bigger on hot (while its running) without downtime.
> 
> Ive been researching a little on this and making some testing but cant get it to work with Docker Swarm. If i do i ll add a comment with the docker-compose.yml as a possible example.

> Thanks!
