ChefDK is now EOL and will receive no further updates. It has been replaced with Chef Workstation. Download Chef Workstation for the latest features and tools.
ChefDK brings Chef Infra Client and the development tools developed by the Chef Community together and acts as the consistent interface to this awesomeness. This awesomeness is composed of:
- Chef Infra Client
- Chef InSpec
- Test Kitchen
- ChefSpec
- Cookstyle
- Delivery CLI
- Push Jobs Client
- Berkshelf
This repository contains the code for the chef command. The full
package is built with omnibus. Project and component build definitions
are in the omnibus directory in this repository.
You can get the latest release of ChefDK from the downloads page.
On macOS, you can also use homebrew-cask
to brew cask install chef/chef/chefdk.
Once you install the package, the chef-client suite, berks,
kitchen, and this application (chef) will be symlinked into your
system bin directory, ready to use.
The following commands will download the latest ChefDK package from the current channel. The current channel holds builds that have passed testing and are candidates for release.
More information about flags supported by install.sh available here: https://docs.chef.io/api_omnitruck.html
In a terminal, run:
curl https://omnitruck.chef.io/install.sh | sudo bash -s -- -c current -P chefdk
To download a specific version, append the -v flag. EG, -v 0.9.0.
Open up a Powershell command prompt as Administrator and run:
. { iwr -useb https://omnitruck.chef.io/install.ps1 } | iex; install -channel current -project chefdk
To download a specific version, append the -version flag. EG, -version 0.9.0.

Our goal is for chef to become a workflow tool that builds on the
ideas of Berkshelf to provide an awesome experience that encourages
quick iteration and testing (and makes those things easy) and provides a
way to easily, reliably, and repeatably roll out new automation code to
your infrastructure.
While we've got a long way to go before we reach that goal we do have
some helpful bits of functionality already included in the chef
command:
The generate subcommand generates skeleton Chef Infra code layouts so you can skip repetitive boilerplate and get down to automating your infrastructure quickly. Unlike other generators, it only generates the minimum required files when creating a cookbook so you can focus on the task at hand without getting overwhelmed by stuff you don't need.
The following generators are built-in:
chef generate cookbookCreates a single cookbook.chef generate recipeCreates a new recipe file in an existing cookbook.chef generate attributeCreates a new attributes file in an existing cookbook.chef generate templateCreates a new template file in an existing cookbook. Use the-s SOURCEoption to copy a source file's content to populate the template.chef generate fileCreates a new cookbook file in an existing cookbook. Supports the-s SOURCEoption similar to template.
The chef generate command also accepts additional --generator-arg key=value
pairs that can be used to supply ad-hoc data to a generator cookbook.
For example, you might specify --generator-arg database=mysql and then only
write a template for recipes/mysql.rb if context.database == 'mysql'.
chef gem is a wrapper command that manages installation and updating
of rubygems for the Ruby installation embedded in the ChefDK package.
This allows you to install knife plugins, Test Kitchen drivers, and
other Ruby applications that are not packaged with ChefDK.
Gems are installed to a .chefdk directory in your home directory; any
executables included with a gem you install will be created in
~/.chefdk/gem/ruby/2.1.0/bin. You can run these executables with
chef exec, or use chef shell-init to add ChefDK's paths to your
environment. Those commands are documented below.
chef exec <command> runs any arbitrary shell command with the PATH
environment variable and the ruby environment variables (GEM_HOME,
GEM_PATH, etc.) setup to point at the embedded ChefDK omnibus environment.
chef shell-init SHELL_NAME emits shell commands that modify your
environment to make ChefDK your primary ruby. It supports bash, zsh,
fish and PowerShell (posh). For more information to help you decide if
this is desirable and instructions, see "Using ChefDK as Your Primary
Development Environment" below.
chef install reads a Policyfile.rb document, which contains a
run_list and optional cookbook version constraints, finds a set of
cookbooks that provide the desired recipes and meet dependency
constraints, and emits a Policyfile.lock.json describing the expanded
run list and locked cookbook set. The Policyfile.lock.json can be used
to install the cookbooks on another machine. The policy lock can be
uploaded to a Chef Infra Server (via the chef push command) to apply the
expanded run list and locked cookbook set to nodes in your
infrastructure. See the POLICYFILE_README.md for further details.
chef push POLICY_GROUP uploads a Policyfile.lock.json along with the cookbooks it
references to a Chef Infra Server. The policy lock is applied to a
POLICY_GROUP, which is a set of nodes that share the same run list and
cookbook set. This command operates in compatibility mode and has the
same caveats as chef install. See the POLICYFILE_README.md for further
details.
chef update updates a Policyfile.lock.json with the latest cookbooks
from upstream sources. It supports an --attributes flag which will
cause only attributes from the Policyfile.rb to be updated.
chef diff shows an itemized diff between Policyfile locks. It can
compare Policyfile locks from local disk, git, and/or the Chef Infra Server,
based on the options given.
chef verify tests the embedded applications. By default it runs a
quick "smoke test" to verify that the embedded applications are
installed correctly and can run basic commands. As an end user this is
probably all you'll ever need, but verify can also optionally run unit
and integration tests by supplying the --unit and --integration
flags, respectively.
You can also focus on a specific suite of tests by passing it as an argument.
For example chef verify git will only run the smoke tests for the git suite.
WARNING: The integration tests will do dangerous things like start HTTP servers with access to your filesystem and even create users and groups if run with sufficient privileges. The tests may also be sensitive to your machine's configuration. If you choose to run these, we recommend to only run them on dedicated, isolated hosts (we do this in our build cluster to verify each build).
By default, ChefDK only adds a few select applications to your PATH
and packages them in such a way that they are isolated from any other
Ruby development tools you have on your system. If you're happily using
your system ruby, rvm, rbenv, chruby or any other development
environment, you can continue to do so. Just ensure that the ChefDK
provided applications appear first in your PATH before any
gem-installed versions and you're good to go.
If you'd like to use ChefDK as your primary Ruby/Chef Infra development environment, however, you can do so by initializing your shell with ChefDK's environment.
To try it temporarily, in a new terminal session, run:
eval "$(chef shell-init SHELL_NAME)"where SHELL_NAME is the name of your shell (usually bash, but zsh is
also common). This modifies your PATH and GEM_* environment
variables to include ChefDK's paths (run without the eval to see the
generated code). Now your default ruby and associated tools will be
the ones from ChefDK:
which ruby
# => /opt/chefdk/embedded/bin/rubyTo add ChefDK to your shell's environment permanently, add the initialization step to your shell's profile:
echo 'eval "$(chef shell-init SHELL_NAME)"' >> ~/.YOUR_SHELL_PROFILEWhere YOUR_SHELL_PROFILE is ~/.bash_profile for most bash users,
~/.zshrc for zsh, and ~/.bashrc on Ubuntu.
You can use chef shell-init with PowerShell on Windows.
To try it in your current session:
chef shell-init powershell | Invoke-ExpressionTo enable it permanently:
"chef shell-init powershell | Invoke-Expression" >> $PROFILEchef shell-init also supports fish.
To try it:
eval (chef shell-init fish)To permanently enable:
echo 'eval (chef shell-init SHELL_NAME)' >> ~/.config/fish/config.fishYou can uninstall ChefDK on Mac using the below commands.
First, remove the main package files:
# Remove the installed files
sudo rm -rf /opt/chefdk
# Remove the system installation entry
sudo pkgutil --forget com.getchef.pkg.chefdkNext, remove the symlinks which the ChefDK installs:
# Symlinks are in /usr/local/bin
ls -la /usr/local/bin | egrep '/opt/chefdk' | awk '{ print $9 }' | sudo xargs -I % rm -f /usr/local/bin/%You can use Add / Remove Programs on Windows to remove the Chef Development
Kit from your system.
You can use rpm to uninstall ChefDK on RHEL based systems:
rpm -qa *chefdk*
yum remove <package>
rm -rf /opt/chefdk
rm -rf ~/.chefdkYou can use dpkg to uninstall ChefDK on Ubuntu based systems:
dpkg --list | grep chefdk # or dpkg --status chefdk
# Purge chefdk from the system.
# see man dkpg for details
dpkg -P chefdkFor information on contributing to this project see https://github.com/chef/chef/blob/master/CONTRIBUTING.md
