Hello,

I would like somebody to confirm my suspicions with CentOS 8 as a Docker host.

My problem is that I can not get the containers to talk to each other. Neither Kibana is connecting to Elasticsearch nor are the node containers joining the same cluster.

To take all of my own incompetence out of the picture I used the example compose file from the docs. [https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html)

Still the same problem. I can ping the other containers as well as access Elasticsearch from a different computer. But the nodes won't join any cluster inside or outside of docker.

I do not have this problem with Debian, Ubuntu, OSX or even Windows.

If anyone has time to give it a try I would appreciate it.

Thanks
