Deploying a multi-node Elixir cluster in something like Kubernetes

[Nam Chu Hoai]

Hi all,

I'm currently exploring Elixir/Phoenix in our organization and while a lot of things looks amazing, I'm struggling to find more elaborate documentation when it comes to deploying as a multi-node cluster? Most content out there is focused on either single-node deployments, or provisioning nodes manually for connectivity in a cluster. We are using tools akin to Kubernetes/Mesos where it would be trivial to bring up "nodes", but getting them to communicate seems like an exotic task for now?

What I've been doing is just trying to network node connect to a set of pre-configured nodes, if any connect then it succeeds, if all fail then it assumes that it is the first one up.

I'm struggling with the same thing. In every example I find (like Chris McCord's great article on Dockyard: https://dockyard.com/blog/2016/01/28/running-elixir-and-phoenix-projects-on-a-cluster-of-nodes), the node names are specified. In a situation where the scaling is being done automatically, how do we assign a node a unique name and then connect it to other nodes on the network?

I'm looking at us convox.com to run a set of autoscaled nodes in a virtual private cloud on AWS.
