Monitoring with god? about capistrano-puma

[Matt888]

I was able to get it working with God by using this for the config. Still testing it out to see if it'll work in all cases, but so far so good:

puma_pid = "#{rails_root}/tmp/pids/puma.pid"
puma_state = "#{rails_root}/tmp/pids/puma.state"

God.watch do |w|
  w.dir = "#{rails_root}"
  w.name = "puma"
  w.env = {"RAILS_ENV"=>rails_env}
  w.pid_file = "#{puma_pid}"
  w.start = "bundle exec puma -C #{rails_root}/config/puma.rb"
  w.stop = "bundle exec pumactl -S #{puma_state} stop"
  w.restart = "bundle exec pumactl -S #{puma_state} restart"
end

I also had to comment out require 'capistrano/puma' in the Capfile because I use god to restart the processes in deploy.rb:

namespace :deploy do
  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      within(current_path) do
        # Reload god and restart its processes
        execute :bundle, "exec god load config/app.god"
        execute :bundle, "exec god restart puma"
      end
    end
  end

There is a alpha support for monit if you want to keep your application up.
by adding : require 'capistrano/puma/monit' to the Capfile

I didn't know about that god gem. I will look into it and report back.

God is basically a 'monit like' written in ruby. If you want to write the tasks, i will merge them.

this gem don't restart puma automatically , so it should not interfere with your setting.

IMO you should not trust a ruby daemon watch over processes.
