Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

delivery-sugar

Delivery Sugar is a library cookbook that includes a collection of helpful sugars and custom resources that make creating build cookbooks for Chef Delivery projects a delightful experience.

Installation

If you are using Berkshelf, add delivery-sugar to your Berksfile:

cookbook 'delivery-sugar'

Usage

In order to use Delivery Sugar in your build cookbook recipes, you'll first need to declare your dependency on it in your metadata.rb.

depends 'delivery-sugar'

Declaring your dependency will automatically extend the Recipe DSL, Chef::Resource and Chef::Provider with helpful methods. It will also automatically make available the custom resources included with Delivery Sugar.

There is no need to include Delivery Sugar in any of your recipes

API

Test Kitchen

The resource delivery_test_kitchen will enable your projects to use Test Kitchen in Delivery. Currently, we only support the kitchen-ec2 driver.

Prerequisites

In order to enable this functionality, perform the following prerequisite steps:

  • Add the following items to the appropriate data bag as specified in the Handling Secrets section

    delivery-secrets <ent>-<org>-<project> encrypted data bag item json { "id": "<ent>-<org>-<project>", "ec2": { "access_key": "<ec2-access-key>", "secret_key": "<ec2-secret-key>", "keypair_name": "<ec2-keypair-name>", "private_key": "<JSON-compatible-ec2-keypair-private-key-content>" } } You can convert the private key content to a JSON-compatible string with a command like this: ruby -e 'require "json"; puts File.read("<path-to-ec2-private-key>").to_json'

  • Customize your kitchen YAML file with all the required information needed by the kitchen-ec2 driver driver. delivery-sugar will expose the following ENV variabls for use by kitchen:

    • KITCHEN_INSTANCE_NAME - set to the <project-name>-<change-id> values provided by delivery-cli
    • KITCHEN_EC2_SSH_KEY_PATH - path to the SSH private key created from the delivery-secrets data bag

    These variables may be used in your kitchen YAML like the following example:

    ---
    driver:
      name: ec2
      region: us-west-2
      availability_zone: a
      instance_type: t2.micro
      image_id: ami-5189a661
      subnet_id: subnet-19ac017c
      tags:
        Name: <%= ENV['KITCHEN_INSTANCE_NAME'] || 'delivery-kitchen-instance' %>
    
    transport:
      ssh_key: <%= ENV['KITCHEN_EC2_SSH_KEY_PATH'] %>
    
    provisioner:
      name: chef_zero
    
    platforms:
      - name: ubuntu-14.04
    
    suites:
      - name: default
        run_list:
          - recipe[test-build-cookbook::default]
        attributes:
    
    

Usage

Once you have the prerequisites you can use delivery_test_kitchen anywhere in your project pipeline, you just need to call the resource within your build-cookbook of your project.

Examples

Trigger a kitchen test using Ec2 driver

delivery_test_kitchen 'functional_test' do
  driver 'ec2'
end

Trigger a kitchen converge & destroy action using Ec2 driver and poiting to .kitchen.ec2.yml file inside the repository path in Delivery.

delivery_test_kitchen 'quality_converge_destroy' do
  yaml '.kitchen.ec2.yml'
  driver 'ec2'
  repo_path delivery_workspace_repo
  action [:converge, :destroy]
end

Trigger a kitchen create passing extra options for debugging

delivery_test_kitchen 'unit_create' do
  driver 'ec2'
  options '--log-level=debug'
  suite 'default'
  action :create
end

Handling Secrets (ALPHA)

This cookbook implements a rudimentary approach to handling secrets. This process is largely out of band from Chef Delivery for the time being.

Your build cookbook will look for secrets in the delivery-secrets data bag on the Delivery Chef Server. It will expect to find an item in that data bag named <ent>-<org>-<project>. For example, lets imagine a cookbook called 'delivery-test' that is kept in the 'open-source' org of the 'chef' enterprise so it's data bag name would be chef-open-source-delivery-test.

This cookbook expects this data bag item to be encrypted with the same encrypted_data_bag_secret that is on your builders. You will need to ensure that the data bag is available on the Chef Server before you run this cookbook for the first time otherwise it will fail.

To get this data bag you can use the DSL get_project_secrets to get the contents of the data bag.

my_secrets = get_project_secrets
puts my_secrets['id'] # chef-Delivery-Build-Cookbooks-delivery-truck

If the project item does not exist, delivery-sugar will try to load the secrets of the organization that your project lives in. It will look for an item called <ent>-<org>. For the same example above it would be chef-open-source. This is useful if you would like to share secrets across projects within the same organization.
