Capistrano::Puma

In the current version the gem will expect a puma.rb in the shared directory, if it does not find puma.rb in the expected place it will automatically generate one with sane defaults. Keep in mind this means a puma.rb in the config directory or subdirectories will be ignored. During preparation for deployment you must start the process initially with bundle exec cap $stage puma:start , after starting the process bundle exec cap $stage deploy will work without hanging. The need to start the process initially will be addressed in a future release.

Installation

Add this line to your application's Gemfile:

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

or:

gem 'capistrano3-puma'

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

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_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"
    set :puma_conf, "#{shared_path}/puma.rb"
    set :puma_access_log, "#{shared_path}/log/puma_error.log"
    set :puma_error_log, "#{shared_path}/log/puma_access.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_init_active_record, false
    set :puma_preload_app, true

For Jungle tasks (beta), these options exist:

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

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

tmp/pids tmp/sockets log
