libcluster v2.0.3 Cluster.Strategy.Kubernetes

This clustering strategy works by loading all pods in the current Kubernetes namespace with the configured tag. It will fetch the addresses of all pods with that tag and attempt to connect. It will continually monitor and update it’s connections every 5s.

It assumes that all nodes share a base name, are using longnames, and are unique based on their FQDN, rather than the base hostname. In other words, in the following longname, <basename>@<domain>, basename would be the value configured in

An example configuration is below:

config :libcluster,
  topologies: [
    k8s_example: [
      strategy: Elixir.Cluster.Strategy.Kubernetes,
      config: [
        kubernetes_node_basename: "myapp",
        kubernetes_selector: "app=myapp",
        polling_interval: 10_000]]]
