Commander

Service to run and monitor OS processes.

Quick example

1. Define a map which contains all processes which should be running,

daemons = %{
  custom_service: %{
    command: "customer_service start",
    options: []
  },
  haproxy: %{
    command: "haproxy -f /home/user/haproxy/haproxy.cfg -p /home/user/haproxy/run/haproxy.pid",
    options: []
  }
}

NOTE: Ensure that the commands are avaiable to user under which the commander service is running

2. Start the services using the following command

Commander.start_from_config(daemons)

Intent

commander service is intended to be used in with control-node i.e. control-node library enables building a custom orchestrator which can deploy elixir services. commander is an elixir service which runs and manages non elixir processes. So, control-node in conjunction with commander can run and manage elixir and non-elixir services across a fleet of servers.
