Engine Yard Recipes

Tools to generate, upload, test and apply chef recipes for Engine Yard Cloud.

Installation

gem install engineyard-recipes

Quick Guide

$ cd /path/to/my/app
$ ey-recipes init   # initial scaffolding for cookbooks
$ ey-recipes package somepackage
$ ey-recipes definition somehelpers specific_helper_method
$ git clone git://github.com/damm/ey-dnapi.git /tmp/recipes/ey-dnapi
$ ey-recipes clone /tmp/recipes/ey-dnapi

# then to upload and apply to your environment
$ ey recipes upload --apply

Alternately, you can have chef recipes run during deployment rather than by explicitly running them:

$ cd /path/to/my/app
$ ey-recipes init -d
$ ey-recipes package somepackage

# then deploy to apply recipes
$ ey deploy

Usage

Getting started:

$ cd /path/to/my/app
$ ey-recipes init
    create  cookbooks/main/attributes/recipe.rb
    create  cookbooks/main/definitions/ey_cloud_report.rb
    create  cookbooks/main/libraries/ruby_block.rb
    create  cookbooks/main/libraries/run_for_app.rb
    create  cookbooks/main/recipes/default.rb

$ ey recipes upload
$ ey recipes apply

The -d or --on-deploy flag will setup your application to run recipes during each deployment.

$ cd /path/to/my/app
$ ey-recipes init --on-deploy
    create  deploy/before_migrate.rb
    create  deploy/solo.rb
    create  deploy/cookbooks/main/attributes/recipe.rb
    create  deploy/cookbooks/main/definitions/ey_cloud_report.rb
    create  deploy/cookbooks/main/libraries/ruby_block.rb
    create  deploy/cookbooks/main/libraries/run_for_app.rb
    create  deploy/cookbooks/main/recipes/default.rb

$ ey deploy

Quickly generate recipes from git repositories or local folders. See bottom of README for community examples.

Either repos that describe a recipe such as ey-dnapi:

$ mkdir /tmp/recipes/
$ git clone git://github.com/damm/ey-dnapi.git /tmp/recipes/ey-dnapi
$ ey-recipes clone /tmp/recipes/ey-dnapi

Generate scaffolding for a package/service.

$ ey-recipes package newthing
    create  cookbooks/newthing/attributes/recipe.rb
    create  cookbooks/newthing/recipes/default.rb
    create  cookbooks/newthing/recipes/install.rb
    append  cookbooks/main/recipes/default.rb

Specify an explicit Gentoo package.

$ ey-recipes package gitosis -p dev-util/gitosis-gentoo -v 0.2_p20081028
$ ey-recipes package qt-webkit -p x11-libs/qt-webkit -v 4.4.2 -u

To use a masked package, pass the --unmasked/-u flag, and install the emerge helper described below.

Generate scaffolding for helper functions:

$ ey-recipes definition myhelpers some_helper
    create  cookbooks/mylibrary/definitions/helper1.rb

Development

Tests

The tests are currently a suite of Cucumber tests that run the generators and assert that specific files are generated. It does not test the generated files/recipes against EY Cloud.

bundle exec rake # to run all non-WIP tests
bundle exec rake cucumber:wip # to run all WIP tests

CI

See the latest CI build results on Travis (for ruby 1.8.7, 1.9.3, rbx and jruby)

From the command line:

bundle exec rake travis

Not sure why its failing.

Release

1. Push the changes to master. This triggers the CI build on TravisCI.
2. Wait for the build to complete successfully.1. Bump the VERSION number in lib/engineyard-recipes/version.rb
3. Update the ChangeLog.md file
4. Commit the changes
5. Release

bundle exec rake release
