About Chef Workstation
Chef Workstation contains everything that is needed to start using Chef Infra and Chef InSpec:
- Chef Infra Client
- Chef InSpec
- chef and knife command line tools
- Testing tools such as Test Kitchen, ChefSpec, and Cookstyle
- Everything else needed to author cookbooks and upload them to the Chef Infra Server
Chef Workstation replaces ChefDK, combining all the existing features with new features, such as ad-hoc task support and the new Chef Workstation desktop application.
Chef Infra is a systems and cloud infrastructure automation framework that makes it easy to deploy servers and applications to any physical, virtual, or cloud location, no matter the size of the infrastructure. Each organization is comprised of one (or more) Chef Workstation installations, a single server, and every node that will be configured and maintained by Chef Infra Client. Cookbooks (and recipes) are used to tell Chef Infra Client how each node in your organization should be configured. Chef Infra Client—which is installed on every node—does the actual configuration.
Cookbook Development Workflow
Chef Infra defines a common workflow for cookbook development:
- Create a skeleton cookbook by running chef generate cookbook MY_COOKBOOK_NAME. This will generate a cookbook with a single recipe and testing configuration with ChefSpec and Delivery Local Mode.
- Write cookbook recipes or resources and debug those recipes as they are being written using Cookstyle and Test Kitchen. This is typically an iterative process, where cookbooks are tested as they are developed, bugs are fixed quickly, and then cookbooks are tested again. A text editor—Visual Studio Code, Atom, vim, or any other preferred text editor—is used to author the files in the cookbook.
- Perform acceptance tests. These tests are not done in a development environment, but rather are done against using an environment that matches the production environment as closely as possible.
- When the cookbooks pass all the acceptance tests and have been verified to work in the desired manner, deploy the cookbooks to the production environment.
Chef Workstation packages all the tools necessary to be successful with Chef Infra and InSpec. These tools are combined into native packages for common operating systems and include all the dependencies you need to get started.
The most important tools included in Chef Workstation are:
|Chef CLI||A workflow tool for Chef.|
|Chef Infra Client||The Chef Infra agent.|
|ChefSpec||A unit testing framework that tests resources locally.|
|Cookstyle||A linting tool that helps you write better Chef Infra cookbooks by detecting and automatically correcting style, syntax, and logic mistakes in your code.|
|Test Kitchen||An integration testing framework tool that tests cookbooks across platforms.|
|kitchen-dokken||A Test Kitchen plugin that provides a driver, transport, and provisioner for rapid cookbook testing and container development using Docker and Chef.|
|kitchen-vagrant||A Test Kitchen plugin for local cookbook testing using Vagrant with VirtualBox, Parallels, VMware, and Hyper-V hypervisors|
|kitchen-ec2, kitchen-google, kitchen-azurerm, kitchen-vcenter||Test Kitchen drivers for cookbook testing on common cloud providers|
