Capistrano::pm2 Gem Version

nodejs pm2 support for Capistrano 3.x

Installation

Add this line to your application's Gemfile:

gem 'capistrano', '~> 3.1.0'
gem 'capistrano-pm2'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano-pm2

Usage

Require in Capfile to use the default task:

require 'capistrano/pm2'

The task will run before deploy:restart as part of Capistrano's default deploy, or can be run in isolation with cap production pm2:restart. You can also invoke it in your deploy.rb:

namespace :deploy do
  desc 'Restart application'
  task :restart do
    # invoke 'npm:install'
    invoke 'pm2:restart'
  end

  after :publishing, :restart
end

Available Tasks

cap pm2:delete                     # Delete pm2 application
cap pm2:list                       # Show pm2 application info
cap pm2:logs                       # Watch pm2 logs
cap pm2:restart                    # Restart app gracefully
cap pm2:setup                      # Install pm2 via npm on the remote host
cap pm2:start                      # Start pm2 application
cap pm2:status                     # List all pm2 applications
cap pm2:stop                       # Stop pm2 application
cap pm2:save                       # Save pm2 state so it can be loaded after restart

Configurable options:

set :pm2_app_command, 'main.js'                   # the main program
set :pm2_app_name, fetch(:application)            # name for pm2 app
