The Engine Yard capistrano tasks are for use specifically with Engine Yard Managed services. But can be used as examples for building other tasks as well.
Capistrano >= 2.2.0
NOTE: When using a git repository use Capistrano >= 2.5.3.
bundler to both document and install the
eycap gem to your application. We also recommend the following gems to be configured along side
eycap. Add these to your
group :development, :test do gem 'eycap', :require => false gem 'capistrano', '~> 2.15' gem 'net-ssh', '~> 2.7.0' end
Then run bundle install to install the
eycap and other gem(s).
$ bundle install
Then in your
deploy.rb file you'll need to add the following require statement to the begininng of the file:
Your initial deploy.rb will be provided for you when your servers are provisioned on Engine Yard Managed. In order to deploy your application, you can go to the
RAILS_ROOT folder and run:
$ capify .
This generates the
Capfile and the
config/deploy.rb file for you. You'll replace the
config/deploy.rb file with the
deploy.rb given to you by Engine Yard.
For deploying Rails 3.1 or greater apps using the asset pipeline read more on the linked page.
Setup restart server
Mongrel is the default server, to override this default you'll need to define the following in your
namespace :deploy do task :restart, :roles => :app do # mongrel.restart end task :spinner, :roles => :app do # mongrel.start end task :start, :roles => :app do # mongrel.start end task :stop, :roles => :app do # mongrel.stop end end
Replace the commented out with your server (passenger, unicorn, thin, puma, etc.) and then it will override the default of mongrel.
Deploying to Environment
To ensure your environments are ready to deploy, check on staging.
$ cap staging deploy:check
This will determine if all requirements are met to deploy. Sometimes if the default folders are not setup you may be able to repair by running:
$ cap staging deploy:setup
If you cannot get
deploy:check to pass, please open a new support ticket and let us know.
Now you're ready to do a test deploy.
cap deploy:cold will run your migrations and start (instead of restart) your app server.
$ cap staging deploy:cold
Or if you have already dumped a copy of your data to staging or do not want to run migrations you can simply do a deploy.
$ cap staging deploy
And to do all this on production, just change the environment name and you'll be all set.
$ cap production deploy
For a list of all available commands, run:
$ cap -T
This will show you not only the default capistrano commands but also the ones you get by including the eycap gem.
Custom binaries path
In rare cases (
sphinx) it is required to set custom path for binaries when using
development versions of scripts. It is as easy as:
set :engineyard_bin, "/engineyard/custom"
The default is
/engineyard/bin and is just fine in normal deployment.
If you'd like to contribute to the eycap gem please create a fork, then send a pull request and a member of the eycap team will review it.
When you run into a problem please check the issues to see if one has been reported. If not, please report the issue and we'll get to work on fixing it.
