Foreman::Monit

Small command-line too to export from Procfile to monit control files

Installation

Add this line to your application's Gemfile:

gem 'foreman-monit', github: 'capita/foreman-monit'
or
gem 'foreman-monit, '~> v1.0.4'

And then execute:

$ bundle

Usage

'foreman-monit export' outputs a monit control file for every process listed in the given Procfile. foreman-monit has to be called from the projects root directory and outputs to /tmp/foreman-monit per default. It is most useful in deployment via Capistrano to automate restarting of processes or changing the processes configuration/definition after or inside your deployment routine

You have to provide --user, --env and --app to specify the user that will be running the processes, the RAILS_ENV to use an a general application-indentifier to name control files and groups accordingly. Additional parameters are --target, which specifies a non-default directory to store the control files in, and --procfile if your Procfile resides outside of the directory you call foreman-monit from.

Inside your procfile, you can use PORT, PID_FILE and RAILS_ENV in your process command, e.g.

web: bundle exec puma -p $PORT --pidfile $PID_FILE
worker: bundle exec rake resque:work PIDFILE=$PID_FILE

Monit will fork the command in a shell for the specified user and will redirect each output to .//-.log

Include the newly exported control files in your monitrc (which normally resides in /etc/monit/monitrc or /etc/monit) with a include /tmp/foreman-monit/.conf or include /your/path/to/foreman-monit/.conf

and simply reload/restart monit with /etc/init.d/monit reload (or restart)

You can start or stop the app's jobs by issuing

monit -g <app> start
monit -g <app> stop

or

monit -g <app> restart

which will typically be somewhere in your 'cap:restart' definition in your Capfile ,e.g.

monit stop -g <app>
foreman-monit export --app <app> --user <user> --env production
monit reload
monit start -g <app>

Exporter options

Required:

  • --app: Name of the app in your Procfile (e.g. shop)
  • --env: Rails environment to pass as RAILS_ENV (e.g. production)
  • --user: Username that will run the process

Optional:

  • --chruby: Calls chruby to switch to the given ruby version
  • --procfile: Location of the Procfile
  • --target: Directory to put the config file, defaults to /tmp/foreman-monit
