Mina Puma

Mina tasks for handle with Puma.

This gem provides several mina tasks:

mina puma:phased_restart  # Restart puma (with zero-downtime)
mina puma:restart         # Restart puma
mina puma:start           # Start puma
mina puma:stop            # Stop puma

Installation

Add this line to your application's Gemfile:

gem 'mina-puma', :require => false

And then execute:

$ bundle

Or install it yourself as:

$ gem install mina-puma

Note: by just including this gem, does not mean your development server will be Puma, for that, you need explicitly add gem 'puma' to your Gemfile.

Usage

Add this to your config/deploy.rb file:

require 'mina/puma'

Make sure the following settings are set in your config/deploy.rb:

• deploy_to - deployment path

Make sure the following directories exists on your server:

• shared/tmp/sockets - directory for socket files.
• shared/tmp/pids - directory for pid files.

OR you can set other directories by setting follow variables:

• puma_socket - puma socket file, default is shared/tmp/sockets/puma.sock
• puma_pid - puma pid file, default shared/tmp/pids/puma.pid
• puma_state - puma state file, default shared/tmp/sockets/puma.state
• pumactl_socket - pumactl socket file, default shared/tmp/sockets/pumactl.sock

Then:

$ mina puma:start

Example

require 'mina/puma'

task :setup => :environment do
  # Puma needs a place to store its pid file and socket file.
  queue! %(mkdir -p "#{deploy_to}/#{shared_path}/tmp/sockets")
  queue! %(chmod g+rx,u+rwx "#{deploy_to}/#{shared_path}/tmp/sockets")
  queue! %(mkdir -p "#{deploy_to}/#{shared_path}/tmp/pids")
  queue! %(chmod g+rx,u+rwx "#{deploy_to}/#{shared_path}/tmp/pids")

  ...

end

task :deploy do
  deploy do
    invoke :'git:clone'
    invoke :'deploy:link_shared_paths'
    ...

    to :launch do
      ...
      invoke :'puma:phased_restart'
    end
  end
end
