ProcessBot

Run your app through ProcessBot for automatic restart if crashing, but still support normal deployment through Capistrano.

Watch memory usage for Sidekiq and restart gracefully if it exceeds a given limit (to counter memory leaks).

When deploying can gracefully exit Sidekiq to let long running jobs finish on old version of code, and start new Sidekiq processes after finishing deploy (but still let the old ones finish gracefully so nothing gets interrupted). This requires not to remove columns, rename columns or any other intrusive database changes.

Add this line to your application's Gemfile:

gem 'process_bot'

Add to your Capfile:

require "process_bot"
install_plugin ProcessBot::Capistrano::Sidekiq
install_plugin ProcessBot::Capistrano::Puma

Add to your deploy.rb:

after "deploy:starting", "process_bot:sidekiq:graceful"
after "deploy:published", "process_bot:sidekiq:start"
after "deploy:failed", "process_bot:sidekiq:start"

Run commands in the command line like this:

cap production process_bot:sidekiq:graceful
