Chef Server

This repository is the central repository for the Chef server.

If you want to file an issue about Chef Server or contribute a change, you're in the right place.

If you need to file an issue against another Chef project, you can find a list of projects and where to file issues in the community contributions section of the Chef docs.

Components of the Chef Server

This repository contains the core services that make up the Chef Server.

|-- oc-chef-pedant: A comprehensive test suite for the Chef Server API
|-- omnibus: Omnibus build configuration for the Chef Server
|-- scripts: Utility scripts
`-- src
    |-- bookshelf: S3-compatible engine for storing cookbook data
    |-- chef-mover: data migration orchestrator used in upgrades
    |-- oc-id: OAuth2 provider for extensions like Analytics or Supermarket
    |-- oc_bifrost: Chef Server's authorization service
    |-- oc_erchef: The core REST API server
    `-- opscode-expander: a service that transforms Chef data before sending it to Solr for indexing

Working on the Chef Server

The quickest way to get a Chef Server development environment is to follow the instructions in the dev directory. This environment is based on Vagrant and features hot reloading of code.

Building a Chef Server package locally:

You can build a Chef Server package locally with vagrant and test-kitchen.

cd omnibus/
make dev dev-build

Once the build is complete, the package should be in omnibus/pkg. By default the dev-build target will create an Ubuntu 10.04 build.

Habitized Chef Server

The following components now exist as Habitat packages and are available here:

• nginx
• bookshelf
• oc_id
• oc_erchef
• oc_bifrost
• chef-server-ctl

To build the packages locally:

./habitat_pkgs_build.sh

A top-level docker-compose.yml file exists for running Chef Server from Habitized Docker images:

docker-compose down && docker system prune --volumes -f && docker-compose up

Running pedant tests:

docker-compose exec chef-server-ctl chef-server-test

Running chef-server-ctl:

docker-compose exec chef-server-ctl chef-server-ctl command (subcommands)

Dependencies contained in other repositories

• knife-ec-backup, used to ease migrations from Open Source Chef Server 11 (and below)
• knife-opc, used to provide administrative command-line control to the Chef Server from the console

Major Technologies used in Chef Server

• Erlang
• PostgreSQL
• RabbitMQ
• Redis
• Solr4
• Nginx (openresty with lpeg library addition)
• Runit for service supervision

If you're looking to contribute to certain parts of the Chef server, familiarity with the following related tools is also beneficial, depending on the area.

• rebar (used for dependency management in Erlang)
• sqitch (database migrations)
• lua (routing rules in openresty)

ACC Pipeline & Chef Expeditor

Chef Software, Inc. leverages an internal Chef Automate installation, commonly referred to as ACC, to "drink our own champagne" and easily test and leverage builds of our products as they are created. The chef/chef-server repository, like many other Chef Software repositories, leverages an internal utility called Chef Expeditor to create a pub-sub model of actions across our various CI/CD utilities.

One of those actions is creating a change in our internal Chef Automate instance every time we successfully generate an omnibus build of Chef Server. This change allows us to easily perform a complex matrix of test suites, followed by a deployment to our internal Chef Server that we use to drive our internal infrastructure. While there is code to support this pipeline in the repository (.delivery/**, terraform/**, and cookbooks/chef-server-deploy/**), this repository does not depend on Chef Automate to handle pull requests.

The resources listed above that drive this pipeline, while open source, are not intended or supported for use outside of ACC as they have dependencies that are unique to Chef Software. However, please feel free to reference them for your own implementations. If you have any questions about these resources, please feel free to reach out in the Chef Community Slack.
