Callback when node has been restored about discovery HOT 3 CLOSED

@cjimison yes, but it's not super clear how to do it because I've got a bit of work to do in naming and documentation. This is what you are looking for:

defmodule MyApp.Supervisor do
  def init([]) do
    children = [
      worker(Discovery.Poller, ["my_service", [
        {Discovery.Handler.NodeConnect, [
          {MyEventHandler, []}
        ]}
      ]], id: :my_service),
    ]

    supervise(children, strategy: :one_for_one)
  end
end

defmodule MyEventHandler do
  use Discovery.NodeConnector.Handler

  def on_connect(node, service, state), do: state
  def on_disconnect(node, service, state), do: state
end

The event handler will fire each time a connect / disconnect event is fired

from discovery.

Bad ass, this is exactly what I needed to know! I saw the NodeConnector.Handler in the code base, just wasn’t sure how add my own via the publicly exposed API (and I am now happily reverting my hacks :).

Thanks for the help!

@cjimison no problem at all, this is something I need to make more clear in the documentation!
