Clustering for your Elixir / Phoenix App

Elixir apps support clustering out of the box. Clustering can bring many advantages like:

Distributed caching
Fault tolerance
Distributing workload across cluster

libcluster

If you wish to use clustering in your application please make sure you have :libcluster installed as a dependency. We also have a hex package that will make clustering in your application easy.

def deps do
  [
    {:libcluster, "~> 3.0"},
    {:libcluster_uplink, "~> 0.2.0"}
  ]
end

Then simply add the following to your runtime config.

config :libcluster,
  topologies: [
    example: [
      strategy: Cluster.Strategy.Uplink,
      config: [
        app_name: "example-app"
      ]
    ]
  ]

This will enable automated clustering for your application inside the OpsMaru provisioned cluster.
