habitat-build

A build cookbook for running the parent project through Chef Automate.

This build cookbook should be customized to suit the needs of the parent project. Do this by "wrapping" the cookbook as a dependency in your project's build cookbook.

Add to your build cookbook's metadata.rb:

depends 'delivery-sugar'
depends 'delivery_build'
depends 'habitat-build'
depends 'delivery-truck'

Add to your build cookbook's Berksfile:

source "https://supermarket.chef.io"

metadata

cookbook 'delivery-truck'
cookbook 'delivery-sugar', git: 'https://github.com/chef-cookbooks/delivery-sugar.git'
cookbook 'habitat-build',  git: 'https://github.com/chef-cookbooks/habitat-build.git'

Include habitat-build recipes in your build cookbook's phase recipes. For example in your build cookbook's lint recipe:

include_recipe 'habitat-build::lint'

Your project must have a ./habitat directory that contains the plan.sh file and other files as necessary for your project to be packaged by Habitat - for example default.toml, or the run script.

Attributes

  • node['habitat-build']['depot-url']: URL to the Habitat Depot where packages are published.
  • node['habitat-build']['shellcheck-excludes']: Array of ShellCheck codes to ignore.

Recipes

default

Sets up a Chef Automate build node so that it can build Habitat packages in a Studio.

deploy

Does nothing in this cookbook.

functional

Does nothing in this cookbook.

lint

Performs a lint check against the habitat/plan.sh using the ShellCheck static analysis tool. Specific codes can be ignored by ShellCheck by adding them to the node attribute array, node['habitat-build']['shellcheck-excludes'].

Note: This attribute will become a Delivery config.json option.

provision

This recipe loads the information from the data bag generated in the publish phase and uses that to promote the artifact the current Delivery stage in Acceptance, Union, Rehearsal, and Delivered stages. It will then be available from the depot for that view in other phases in the stage.

publish

This recipe builds the package with Habitat and publishes it to the configured Habitat Depot (by default, the public Habitat Depot). Change the node['habitat-build']['depot-url'] to an internal depot if necessary. Once the build is complete, this recipe uses the /src/results/last_build.env file for information about the package that was built. It uses hab artifact hash to generate the hash checksum for the package. The information gathered is stored in a data bag, named after the Delivery project_slug, which is generated as enterprise-organization-project by Delivery. The item itself will have a timestamp name like 2016-06-01_1643.

This data bag item is used in the provision recipe to track state changes of the build through the pipeline, as each phase is a separate Chef Client run on the build node.

quality

Does nothing in this cookbook.

security

Does nothing in this cookbook.

smoke

Does nothing in this cookbook.

syntax

Performs a bash syntax check using bash -n against the habitat/plan.sh.

unit

Does nothing in this cookbook.

Libraries

client

The habitat-client Ruby library. This is in the cookbook because we cannot publish it as a RubyGem until we release Habitat to the world. See rdoc comments in libraries/client.rb for more information.

exceptions

Custom exception handlers for habitat-client.

helpers

Cookbook recipe helper methods.

habitat_plan_dir: returns the directory where the plan lives. Searches the delivery/config.json of the build cookbook configuration, followed by an attribute, and falls back to /src/habitat.

habitat_origin_key?: predicate method that returns true if there's a data bag item for the project's secrets in Chef Delivery, and if it has non-empty origin secrets in a hash key habitat, keyname, private_key, public_key.

habitat_depot_token?: predicate method that returns true if there's a data bag item for the project's secrets in Chef Delivery, and if it has non-empty origin secrets in a hash key habitat, depot_token.
