chef (executable)

The chef executable is a command-line tool that does the following:

Generates repositories, cookbooks, recipes, attributes, templates, and custom resources.
Installs gems into the Chef development environment’s Ruby installation.
Helps you manage your Policyfiles. Please refer the Policyfile commands section.

Note

By default, the cookbook cache is located in ~/.chef-workstation on macOS and Linux, and in %LOCALAPPDATA%\chef-workstation on Windows. On macOS or Linux, set the desired location of the cache directory by setting the CHEF_WORKSTATION_HOME environment variable in your .bashrc or zshrc file. For example, CHEF_WORKSTATION_HOME="~/.workstation". On Windows, use the setx command or access the Advanced tab in System Properties to set the CHEF_WORKSTATION_HOME environment variable.

chef capture

Use the chef capture subcommand to capture a node’s state as a local chef-repo. Use the generated repository if you need to converge a node locally.

Syntax

This subcommand has the following syntax:

chef capture NODE-NAME [options]

Options

-c, --credentials: Credentials file (default $HOME/.chef/credentials).
-d, --with-data-bags: Download all data bags as part of node capture.
-h, --help: Show help for the command.
-k, --client-key: Chef Infra Server API client key.
-n, --client-name: Chef Infra Server API client name.
-o, --ssl-no-verify: Do not verify SSL when connecting to Chef Infra Server (default: verify).
-p, --profile: Profile to use from credentials file (default “default”).
-s, --chef-server-url: Chef Infra Server URL.

Examples

Capture a node

To capture a node in a local repository, run a command similar to:

chef capture test-server

This will return something similar to:

- Setting up local repository
 - Capturing node object 'test-server'
 - Capturing policy data...
 - Capturing cookbook artifacts...
 - Writing kitchen configuration...

Repository has been created in './node-test-server-repo'.

Next, locate version-controlled copies of the cookbooks. This is
important so that you can track changes to the cookbooks as you
edit them. You may have one or more existing paths where you have
checked out cookbooks. If not, now is a good time to open a
separate terminal and clone or check out the cookbooks.

If all cookbooks are not available in the same base location,
you will have a chance to provide additional locations.

Press Enter to Continue:

You're ready to begin!

Start with 'cd ./node-test-server-repo; kitchen converge'.

As you identify issues, you can modify cookbooks in their
original checkout locations or in the repository's cookbooks
directory and they will be picked up on subsequent runs
of 'kitchen converge'.

chef shell-init

Use the chef shell-init subcommand to set the Ruby included in Chef Workstation as the system Ruby. Chef Workstation is designed to allow the isolation of applications used by Chef Workstation from other Ruby development tools that may be present on the workstation. This supports Bash, fish, Windows PowerShell (posh), and zsh.

Syntax

This subcommand has the following syntax:

chef shell-init SHELL_NAME (options)

Options

This subcommand has the following options:

-h, --help: Show help for the command.

Examples

Set PowerShell

You can use the chef shell-init command with Windows PowerShell to add the appropriate variables to your environment.

To try it in your current session:

chef shell-init powershell | Invoke-Expression

To enable it permanently:

"chef shell-init powershell | Invoke-Expression" >> $PROFILE

Set the execution policy on new machines

On new Windows machines, PowerShell scripts will not work until an administrator runs the following command:

Set-ExecutionPolicy RemoteSigned

Create a $PROFILE on new machines

On new Windows machines, commands cannot be appended to $PROFILE if the folder does not exist, or if there is a new user profile. This will result in an error similar to the following:

PS C:\Users\Stuart> "chef shell-init powershell | Invoke-Expression" >> $PROFILE
out-file : Could not find a part of the path
'C:\Users\Stuart\Documents\WindowsPowerShell\Microsoft.PowerShell_profile.ps1'.
At line:1 char:1
+ "chef shell-init powershell | Invoke-Expression" >> $PROFILE
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : OpenError: (:) [Out-File], DirectoryNotFoundException
    + FullyQualifiedErrorId : FileOpenFailure,Microsoft.PowerShell.Commands.OutFileCommand

In this situation, run the following chef shell-init command instead:

if(Test-Path $PROFILE){ chef shell-init powershell | Add-Content $PROFILE } else { New-Item -Force -ItemType File $PROFILE; chef shell-init powershell | Add-Content $PROFILE }

chef install

Use the chef install subcommand to evaluate a Policyfile and find a compatible set of cookbooks, build a run-list, cache it locally, and then emit a Policyfile.lock.json file that describes the locked policy set. The Policyfile.lock.json file may be used to install the locked policy set to other machines and may be pushed to a policy group on the Chef Infra Server to apply that policy to a group of nodes that are under management by Chef.

Syntax

This subcommand has the following syntax:

chef install POLICY_FILE (options)

Options

This subcommand has the following options:

-D, --debug: Enable stack traces and other debug output.

Policyfile.lock.json

When the chef install command is run, Chef Workstation caches any necessary cookbooks and emits a Policyfile.lock.json file that describes:

The versions of cookbooks in use
A hash of cookbook content
The source for all cookbooks
Attributes included with the Policyfile

A Policyfile.lock.json file is associated with a specific policy group, which means it is associated with one (or more) nodes that use the same revision of a given policy.

A Policyfile.lock.json file is similar to:

chef show-policy

Use the chef show-policy subcommand to display revisions for every Policyfile.rb file that is on the Chef Infra Server. By default, only active policy revisions are shown. When both a policy and policy group are specified, the contents of the active Policyfile.lock.json file for the policy group is returned.

Syntax

This subcommand has the following syntax:

chef show-policy POLICY_NAME POLICY_GROUP (options)

Options

This subcommand has the following options:

-c CONFIG_FILE, --config CONFIG_FILE: The path to the knife configuration file.

chef undelete

Use the chef undelete subcommand to recover a deleted policy or policy group. This command:

Does not detect conflicts. If a deleted item has been recreated, running this command will overwrite it
Does not include cookbooks that may be referenced by Policyfiles; cookbooks that are cleaned after running this command may not be fully restorable to their previous state
Does not store access control data

Syntax

This subcommand has the following syntax:

chef undelete (options)

When run with no arguments, returns a list of available operations.

Options

--list: Default. Return a list of available operations.
-v, --version: The Chef Infra Client version.

Examples

None.

chef update

Use the chef update subcommand to read the Policyfile.rb file, and then apply any changes. This will resolve dependencies and will create a Policyfile.lock.json file. The locked policy will reflect any changes to the run-list and will pull in any cookbook updates that are compatible with any version constraints defined in the Policyfile.rb file.

Syntax

This subcommand has the following syntax:

chef update POLICY_FILE (options)

Options

This subcommand has the following options:

-a, --attributes: Update attributes. Default value: false.
