Using Rancher Server v1.4.3
We’ve configured HA with two backend Rancher Servers. Each node is front-ended (SSL) with the nGinx servers, so to a Load Balancer, the servers are accessible on the SSL port, and not on the default HTTP port 8080.
Now, when starting each of the nodes, we don’t want to expose the port 8080 at all (for security reasons), so we’ve tried adding the --advertise-http-port 443 (the nGinx SSL port) when starting the server node, but it doesn’t seem to be working and for one, it breaks the exec shell access to the containers.
Is there any workaround allowing us to not expose the 8080 port while still allowing the cluster nodes to communicate?
