= vlad-unicorn

* http://bitbucket.org/krbullock/vlad-unicorn/

== DESCRIPTION:

Unicorn app server support for Vlad. Adds support for vlad:start_app and
vlad:stop_app using Unicorn[http://unicorn.bogomips.org/].

== FEATURES/PROBLEMS:

* Unicorn support for vlad:start_app and vlad:stop_app tasks.

== SYNOPSIS:

    # lib/tasks/vlad.rake
    begin
      require 'vlad'
      Vlad.load(:app => :unicorn)
    rescue LoadError
    end

or for legacy Rails (1.2.x thru 2.2.x) apps

    # lib/tasks/vlad.rake
    begin
      require 'vlad'
      Vlad.load(:app => :unicorn_rails)
    rescue LoadError
    end

rails-configuration.txt[link:docs/rails-configuration_txt.html].

== REQUIREMENTS:

* Vlad[http://rubyhitsquad.com/Vlad_the_Deployer.html]

* Unicorn[http://unicorn.bogomips.org/]

== INSTALL:

    $ sudo gem install vlad-unicorn

== VARIABLES:

unicorn_command::       Defaults to 'unicorn' when using
                        <tt>:app => :unicorn</tt>, and 'unicorn_rails' with
                        <tt>:app => :unicorn_rails.</tt>
unicorn_config::        The location of the Unicorn config file. Defaults to
                        "#{current_path}/config/unicorn.rb".
unicorn_pid::           The location of the Unicorn pid file. Must be the same
                        as in unicorn.rb file. Currently needed for the
                        +stop_app+ task, but hopefully won't be necessary in a
                        future version.
unicorn_rackup::        The location of the rackup file unicorn should load.
                        Defaults to "#{current_path}/config.ru". Not set nor
                        used for +unicorn_rails+.
unicorn_use_sudo::      Whether to use sudo to run the 'unicorn' command on
                        the remote host. Probably necessary if you specify a
                        user and group in unicorn.rb.
unicorn_env::           Environment to be given to unicorn (value for +-E+).
                        Default value is based on +vlad/rails+'s +rails_env+.
                        If +rails_env+ is not defined, +production+ is used as
                        default value. To disable passing an environment, set to
                        +nil+.
unicorn_use_bundler::   Whether to use <tt>bundle exec</tt> to run the 'unicorn'
                        command on the remote host. Defaults to false.
unicorn_bundle_cmd::    How to invoke <tt>bundle exec</tt>. Defaults to
                        <tt>cd #{current_path} && bundle exec</tt>. If you have
                        defined +bundle_cmd+ for Bundler's built-in deployment
                        tasks, vlad-unicorn will use that in place of +bundle+
                        in the above default.

rails-configuration.txt[link:docs/rails-configuration_txt.html].

== TASKS:

start_app, stop_app::   Vlad's built-in tasks to start and stop the application
                        processes, adapted for Unicorn.

reload_app::            Reload unicorn (in case <tt>preload_app == true</tt>).
                        If this is the case, you have to adapt your +before_fork+
                        hook so it kills the old unicorn master and workers.
                        Cf. "Getting started with unicorn"[http://codelevy.com/2010/02/09/getting-started-with-unicorn.html].
