Consulate

The implementation of erl_epmd-compatible module that uses Consul for node discover instead of EPMD.

Usage

Add project to your dependencies

Erlang:

{deps, [consulate]}.

Elixir:

defp deps do
  [
    {:consulate, "~> 0.0"}
  ]
end

And then run your application with

-epmd_module consulate -start_epmd false

Configuration

You can change default erlang-node service name via -consul_service flag to erl. Beware that all nodes that want to be connected need to use the same service name.

Consul connection options are set via application environment. Supported options are:

• host (defaults to 127.0.0.1) - host to Consul agent
• port (defaults to 8500) - port on which agent is listening
• scheme (defaults to http) - connection scheme, can be "http" or "https"
• check - map containing 2 fields:
  • interval (defaults to 10) - time in seconds between each health check
  • deregister (defaults to 60) - time in seconds after which the service will be deregistered from catalog after it fails test
• meta - map of atom() => atom() | binary() pairs that will be submitted as service metadata
