We're looking into it. We optimistically want to do it. We haven't committed to doing it, because we're prioritizing some other stuff right now :P

If doing a docker swarm which ports are required? Not clear on installation documentation.

yes it would be 80 and 443 for http traffic. And the ports that swarm requires for internal communications https://docs.docker.com/engine/swarm/swarm-tutorial/#open-pr...

You just need to open port 80 and 443 for HTTP communication.

Yes, official support is in the pipeline. There have been some community helm charts in the past ( which might need to be updated )
