Delivery CLI

A command line tool for continuous delivery workflow. The delivery command is a component of Chef Delivery. It can be used to setup and execute phase jobs as well as interact with a Chef Delivery server.

It is a part of the ChefDK and can be downloaded here.

Getting Started With Delivery

In particular, you will want to be familar with:


To get started make sure you have the following installed:

Main technologies used in this project:

We use make to perform various development operations like building and testing. The commands reside in the Makefile, but the Makefile is only used for development. It is not used by omnibus or our delivery cookbooks.

Make targets:

  • make builds the project.
  • make test runs the unit and functional tests.
  • make cucumber will run the cucumber tests.
  • make clean will clean the state of the build.
  • make update_deps will clean the project and update the Cargo.lock file, this should be run periodically to pull in new deps and at the very least when upgrading to a new version of Rust.
  • make release builds the project with the --release flag.
  • make check builds and runs unit tests.

After you make the project, you can execute your compiled binary by running target/debug/delivery <delivery_args>. So, you could run something like

$ target/debug/delivery review

to test the review command with your code in it.

If, for whatever reason, you want to compile and test with cargo's --release flag, run make release, and use target/release/delivery, but it will take longer to compile.

Promoting to Github

Currently, when you hit accept in the Delivery RFR UI, it will merge to delivery master, but not github master. That happens in delivered/functional.


ChefDK builds pull from master of delivery-cli on github, so delivering your changes in the delivery project for delivery-cli will "ship" them to the next build of the ChefDK.


  • You can set the logging level by exporting the RUST_LOG environment variable (e.g RUST_LOG=debug cargo run).

  • Export RUST_BACKTRACE=1 for better stack traces on panics.

  • Run only the embedded unit tests (not functional tests in the tests/ directory nor code embedded in doc comments) via cargo test --lib. You can also pass a module name to only run matching tests (e.g. cargo test --lib job).

  • To test a specific cucumber module, after a bundle install, you can run bin/cucumber features/<feature>.feature.

Cucumber Testing

We heavily rely on git in the project. Some of the cucumber tests mock out parts of git. Those mocks exist in features/support/fakebin/git.

To mock a git call in your cucumber test, set <NAME_OF_GIT_COMMAND>_MOCKED to true in your cucumber test. For example, features/job.feature mocks several git commands with:

  Given I set the environment variables to:
    | variable             | value      |
    | CHECKOUT_MOCKED      | true       |
    | MERGE_MOCKED         | true       |
    | CLEAN_MOCKED         | true       |
    | RESET_MOCKED         | true       |

You can also mock all of git by setting MOCK_ALL_BASH to true:

  Given I set the environment variables to:
    | variable           | value      |
    | MOCK_ALL_BASH      | true       |

NOTE THAT A FEW COMMANDS ARE MOCKED BY DEFAULT STILL! We want to change this eventually. They are:

  • clone
  • push
  • fetch
  • ls-remote
  • show

These commands will never actuall execute until their mocks are refactored out of features/support/fakebin/.

Updating Rust Version

When a new version of Rust comes out and it is on homebrew, it's time to update the Rust version in this repo. There are a few spots to update:

  1. Very top of the Makefile
  2. omnibus-software's default version
  3. The default attributes for the build cookbook for this project

You should also run make release to bump the Cargo.lock file to get new versions of our dependencies.

Delivery Job Implementation Details

The delivery job subcommand is used to execute phase recipes for a project in a workspace. The Delivery server uses delivery job to execute the phases of each stage in the pipeline. The same command can be used locally to execute a phase job in the same way. You can also wire delivery job into your own pipeline orchestration if you are not using the Delivery server.

Jobs are run by specifying the stage and the phase. For example, the following command will run the unit phase of the verify stage:

delivery job verify unit --local

The delivery job subcommand will execute the phase recipe by carrying out the following steps:

  1. Currently, the job command assumes the current branch is a feature branch with commits that are not on the target branch.

  2. Clone the project repository to a workspace. The location can be customized using --job-root.

  3. Merge the feature branch into the target branch. This merge will not be pushed anywhere and is often referred to as "the hypothetical merge"; it is the merge that would result if this change were to be approved at this time.

  4. Fetch the build cookbook for the project. The build cookbook location is specified in the project's .delivery/config.json file.

  5. Use berks to fetch dependencies of the build cookbook (as specified in the build cookbook's Berksfile).

  6. Run chef-client in local mode with a run list consisting of only the default recipe of the build cookbook. The default recipe is intended for preparing a given node to be a "build node" for the project. Typical setup handled in the default recipe might include installing compilers, test frameworks, and other build and test dependencies. The default recipe is skipped when delivery job is invoked by a non-root and when the --skip-default option is specified.

  7. Run chef-client in local mode with a run list consisting of only the specified phase recipe (e.g. unit).

Without the --local option, the command will look for configuration required when interacting with a Delivery server from either .delivery/cli.toml or additional command line options.

For local use, you can run multiple phases within a single run like so:

delivery job verify "lint syntax unit"

Delivery Pipeline For This Project

Omnibus build is how the CLI is built on Delivery build nodes. The omnibus build setup will use the default recipe of the build cookbook (see cookbooks/delivery_rust/recipes/default.rb) and omnibus builds may need sudo permissions for setup.

Node Attributes

Attributes specific to the project and change are made available for use in build cookbook recipes.

The global workspace path is accesssible at node['delivery']['workspace_path']

Workspace Details

Attributes in the node['delivery']['workspace'] namespace provide paths to the various directories in your change's workspace on your build node.

  • node['delivery']['workspace']['root']
  • node['delivery']['workspace']['repo']
  • node['delivery']['workspace']['chef']
  • node['delivery']['workspace']['cache']

Change Details

Attributes in the node['delivery']['change'] namespace provide details about this particular job execution.

  • node['delivery']['change']['enterprise']
  • node['delivery']['change']['organization']
  • node['delivery']['change']['project']
  • node['delivery']['change']['pipeline']
  • node['delivery']['change']['change_id']
  • node['delivery']['change']['patchset_number']
  • node['delivery']['change']['stage']
  • node['delivery']['change']['phase']
  • node['delivery']['change']['git_url']
  • node['delivery']['change']['sha']
  • node['delivery']['change']['patchset_branch']

Project Configuration Details

The contents of your .delivery/config.json file are made available to you in the node['delivery']['config'] namespace.

Note for Git Bash + MinTTY Users

If you're running delivery token on Windows in Git Bash with MintTTY you must include winpty before delivery token to avoid errors.
