Peerage v1.0.2 Peerage.Via.Dns

Use Dns-based service discovery to find other Nodes.

Example

config :peerage, via: Peerage.Via.Dns,
  dns_name: "localhost",
  app_name: "myapp"

Will look up the ip(s) for ‘localhost’, and then try to connect to myapp@$IP.

Kubernetes

Kubernetes supports this out of the box for ‘headless services’ — if you have a service named myapp, doing nslookup myapp in a deployed container will return a list of IP addresses for that service.
