Capazon 0.2 Released - Capistrano 2.0 Compatible

Posted Tue, 01 May 2007 03:01:00 GMT to , , , , by

Capazon 0.2.0 is out. There’s only one new feature: support for Capistrano 2.0. There’s no backwards compatibility. If you’re still on Capistrano 1.4.x, please don’t upgrade. It won’t work.

To update Capazon:

  • gem install capazon

Changes

Capistrano 2.0 has support for Rake-like namespaces, so I’ve moved all tasks provided by Capazon to the ec2 namespace:

$ cap ec2:describe_images
  * executing `ec2:describe_images'
IMAGE   ami-0386636a    rbuilder-online/nuxleus-1.3-x86_9327.img.manifest.xml  099034111737     available       true
IMAGE   ami-0683666f    rbuilder-online/fedoracore6-1.0-x86_9677.img.manifest.xml       099034111737    available       true
[...]

To call these tasks from another namespace in a Capistrano recipe:

namespace :whatever do
  task :something_cool do
    [...]
    ec2.describe_images
    [...]
  end
end

Capistrano 2.0

Turns out updating extensions to work w/ Capistrano 2.0 is extremely easy. Just replace blocks like this:

Capistrano.configuration(:must_exist).load do
  task :take_over_the _world do
    [...]
  end
end

...with this:

Capistrano::Configuration.instance.load do do
  task :take_over_the _world do
    [...]
  end
end
