Cluster Setup / exposing port 5801 in Docker

[Torsten Müller]

Hey Experts,

I am trying to set up a 2-node Confluence DC cluster using the official images. Both nodes are on seperate VMs on the same network.

When NOT exposing port 5801 in my docker-compose file, Node 1 will start fine, but Communication between nodes fails (no firewall involved).

Once I expose port 5801, confluence will not start, raising: "IllegalStateException: Node failed to start!", with the description "Could not load bootstrap from environment"

Again, this only happens if I expose port 5801 on calling docker run or in my docker-compose.yml.

This all happens with a fresh install, official confluence docker image, an empty local home, empty database etc; using confluence 7.13.5 and postgres 11, which is what we are using right now.

Can anyone point me to whatever I may be overlooking here? 

Regards,

Torsten
