God Gem starts Watch if I use w.keepalive, but not if I use $ god sidekiq start
I am afraid to use Sidekiq next to God Gem . I would like to be able to start the sidekiq process manually using $god start sidekiq
, however this cannot start the process. I can get it to start the sidekiq process if I have w.keepalive installed (commented in the code below).
I launch God using:, $ god -c "./config.god" -D --log-level info
launching the god in the foreground, which gets me the following output:
I [2013-01-22 17:46:00] INFO: Started on drbunix:///tmp/god.17165.sock
I [2013-01-22 17:46:00] INFO: sidekiq move 'unmonitored' to 'up'
I [2013-01-22 17:46:00] INFO: sidekiq moved 'unmonitored' to 'up'
Using $god start sidekiq
, I get:
Sending 'start' command
The following watches were affected:
sidekiq
But I have no way out from God, nothing is written in sidekiq magazine, and I can clearly see that the sidekiq process did not start with help $ ps auxwww | grep sidekiq
.
# config.god
PROJECT_ROOT = ENV['PROJECT_ROOT'] || File.dirname(__FILE__) # Dir containing this file
# Sidekiq Process
God.watch do |w|
w.name = "sidekiq"
w.group = "conversion"
w.dir = PROJECT_ROOT
w.interval = 20.seconds
w.start_grace = 10.seconds
w.restart_grace = 10.seconds
w.behavior(:clean_pid_file)
# w.keepalive
w.start = "bundle exec sidekiq -v -C #{File.join(PROJECT_ROOT, 'config.yml')}"
w.stop = "bundle exec sidekiqctl stop '/Users/me/.god/pids/sidekiq.pid' 5"
w.log = File.join(PROJECT_ROOT, 'log/god_sidekiq.log')

Try the following:
# config.god
PROJECT_ROOT = ENV['PROJECT_ROOT'] || File.dirname(__FILE__) # Dir containing this file
# Sidekiq Process
pid_file = '/Users/me/.god/pids/sidekiq.pid'
God.watch do |w|
w.name = "sidekiq"
w.group = "conversion"
w.dir = PROJECT_ROOT
w.interval = 20.seconds
w.start_grace = 10.seconds
w.restart_grace = 10.seconds
w.pid_file = pid_file
w.behavior(:clean_pid_file)
w.start = "cd #{PROJECT_ROOT}; bundle exec sidekiq -v -C #{File.join(PROJECT_ROOT, 'config.yml')} -P #{pid_file}&"
w.stop = "cd #{PROJECT_ROOT}; bundle exec sidekiqctl stop #{pid_file} 5"
w.log = File.join(PROJECT_ROOT, 'log/god_sidekiq.log')
# determine the state on startup
w.transition(:init, {true => :up, false => :start}) do |on|
on.condition(:process_running) do |c|
c.running = true
end
end
# determine when process has finished starting
w.transition([:start, :restart], :up) do |on|
on.condition(:process_running) do |c|
c.running = true
end
# failsafe
on.condition(:tries) do |c|
c.times = 5
c.transition = :start
end
end
# start if process is not running
w.transition(:up, :start) do |on|
on.condition(:process_exits)
end
# lifecycle
w.lifecycle do |on|
on.condition(:flapping) do |c|
c.to_state = [:start, :restart]
c.times = 5
c.within = 5.minute
c.transition = :unmonitored
