Capistrano::Puma

Installation

Add this line to your application's Gemfile:

gem 'capistrano3-puma', github: "seuros/capistrano-puma"

or:

gem 'capistrano3-puma' , group: :development

And then execute:

$ bundle

Usage

    # Capfile

    require 'capistrano/puma'
    require 'capistrano/puma/workers' # if you want to control the workers (in cluster mode)
    require 'capistrano/puma/jungle'  # if you need the jungle tasks
    require 'capistrano/puma/monit'   # if you need the monit tasks
    require 'capistrano/puma/nginx'   # if you want to upload a nginx site template

then you can use cap -T to list tasks

cap puma:nginx_config # upload a nginx site config(eg. /etc/nginx/sites-enabled/)
cap puma:config  # upload puma config(eg. shared/puma.config)

you may want to customize these two templates locally before uploading

rails g capistrano:nginx_puma:config

if your nginx server configuration is not located in /etc/nginx, you may need to customize nginx_sites_available_path and nginx_sites_enabled_path

set :nginx_sites_available_path, "/etc/nginx/sites-available"
set :nginx_sites_enabled_path, "/etc/nginx/sites-enabled"

By default, nginx_config will be executed with :web role. But you can assign it to a different role:

set :puma_nginx, :foo

or define a standalone one:

role :puma_nginx, %w{root@example.com}

Configurable options, shown here with defaults: Please note the configuration options below are not required unless you are trying to override a default setting, for instance if you are deploying on a host on which you do not have sudo or root privileges and you need to restrict the path. These settings go in the deploy.rb file.

    set :puma_user, fetch(:user)
    set :puma_rackup, -> { File.join(current_path, 'config.ru') }
    set :puma_state, "#{shared_path}/tmp/pids/puma.state"
    set :puma_pid, "#{shared_path}/tmp/pids/puma.pid"
    set :puma_bind, "unix://#{shared_path}/tmp/sockets/puma.sock"    #accept array for multi-bind
    set :puma_default_control_app, "unix://#{shared_path}/tmp/sockets/pumactl.sock"
    set :puma_conf, "#{shared_path}/puma.rb"
    set :puma_access_log, "#{shared_path}/log/puma_access.log"
    set :puma_error_log, "#{shared_path}/log/puma_error.log"
    set :puma_role, :app
    set :puma_env, fetch(:rack_env, fetch(:rails_env, 'production'))
    set :puma_threads, [0, 16]
    set :puma_workers, 0
    set :puma_worker_timeout, nil
    set :puma_init_active_record, false
    set :puma_preload_app, true
    set :nginx_use_ssl, false

For Jungle tasks (beta), these options exist:

    set :puma_jungle_conf, '/etc/puma.conf'
    set :puma_run_path, '/usr/local/bin/run-puma'

Multi-bind can be set with an array in the puma_bind variable

  set :puma_bind, %w(tcp://0.0.0.0:9292 unix:///tmp/puma.sock)

* Listening on tcp://0.0.0.0:9220
* Listening on unix:///tmp/puma.sock

For ActiveRecord the following line to your deploy.rb

    set :puma_init_active_record, true

Ensure that the following directories are shared (via linked_dirs):

tmp/pids tmp/sockets log
