### In mix.exs
  defp deps do
    [
      ...
      {:libcluster, "~> 3.1"},
      ...
    ]
  end

### In config/prod.exs
config :libcluster,

    your_app: [
      strategy: Cluster.Strategy.Kubernetes.DNS,

        application_name: "yourapp",
        polling_interval: 10_000
      ]
    ]
  ]

### In lib/application.ex

              ]
            }
          ],
          # Start the Ecto repository
