I was not able to reproduce the TLS success. I did run into an immediate issue when patching the svc the ELB in was selects the new port as the health proper which makes all nodes out of service. I fixed that but can not make a connection

@mikedickey this is the best/recommended way to set the communication between nodes? If yes, I can test on my new cluster

We use Istio at Splunk, and it seems to have most traction. Doesn't mean you can't use something else, but we will likely continue to focus on it for examples, testing, etc.
