Add a New Component
To add a new Component Class to a model so it can be used by Platforms, follow these steps:
In this example, we use Jboss as an example of a new component.
- Clone the initial packer directory from git@github.com:kloopz/packer.git
cd packer; util/new_component.rb Jboss
his generates the dirs and files with common values. See the sample output in the first Note below.
cd cookbooks/Jboss
- Update metadata.rb. You can reuse existing Jboss chef recipes and attributes by using the open source recipe, http://community.opscode.com/cookbooks/Jboss. For a list of these see the second Note below.
cd recipes
- Copy recipes from the download on the page above, or use the Git chef-Jboss. The cookbook does not have a recipe named add.rb. Their default.rb does the same function.
- Create an add.rb and update.rb that only has: include_recipe “Jboss::default”. There is no delete recipe, that must be added.
- Update relationships metadata for:
depends_on,deployed_to,escorted_by,managed_via,realized_as,requires, andwatched_by. cd ../<relationship>and edit metadata.rb adding Jboss accordingly.- Sync to CMS.
- Add the Jboss image for the UI: kloopz-app repo
