PROGRAM:

NAME


knife-cookbook - The man page for the knife cookbook subcommand.

A cookbook is the fundamental unit of configuration and policy distribution. Each cookbook
defines a scenario, such as everything needed to install and configure MySQL, and then it
contains all of the components that are required to support that scenario, including:

· Attribute values that are set on nodes

· Definitions that allow the creation of reusable collections of resources

· File distributions

· Libraries that extend the chef-client and/or provide helpers to Ruby code

· Recipes that specify which resources to manage and the order in which those resources
will be applied

· Custom resources and providers

· Templates

· Versions

· Metadata about recipes (including dependencies), version constraints, supported
platforms, and so on

The knife cookbook subcommand is used to interact with cookbooks that are located on the
Chef server or the local chef-repo.

COMMON OPTIONS


The following options may be used with any of the arguments available to the knife
cookbook subcommand:

--chef-zero-port PORT
The port on which chef-zero will listen.

-c CONFIG_FILE, --config CONFIG_FILE
The configuration file to use.

-d, --disable-editing
Use to prevent the $EDITOR from being opened and to accept data as-is.

--defaults
Use to have knife use the default value instead of asking a user to provide one.

-e EDITOR, --editor EDITOR
The $EDITOR that is used for all interactive commands.

-E ENVIRONMENT, --environment ENVIRONMENT
The name of the environment. When this option is added to a command, the command
will run only against the named environment.

-F FORMAT, --format FORMAT
The output format: summary (default), text, json, yaml, and pp.

-h, --help
Shows help for the command.

-k KEY, --key KEY
The private key that knife will use to sign requests made by the API client to the
Chef server.

--[no-]color
Use to view colored output.

--print-after
Use to show data after a destructive operation.

-s URL, --server-url URL
The URL for the Chef server.

-u USER, --user USER
The user name used by knife to sign requests made by the API client to the Chef
server. Authentication will fail if the user name does not match the private key.

-V, --verbose
Set for more verbose outputs. Use -VV for maximum verbosity.

-v, --version
The version of the chef-client.

-y, --yes
Use to respond to all confirmation prompts with "Yes". knife will not ask for
confirmation.

-z, --local-mode
Use to run the chef-client in local mode. This allows all commands that work
against the Chef server to also work against the local chef-repo.

BULK DELETE


The bulk delete argument is used to delete cookbook files that match a pattern defined by
a regular expression. The regular expression must be within quotes and not be surrounded
by forward slashes (/).

Syntax

This argument has the following syntax:

$ knife cookbook bulk delete REGEX (options)

Options

This argument has the following options:

-p, --purge
Use to entirely remove a cookbook (or cookbook version) from the Chef server. This
action should be used carefully because only one copy of any single file is stored
on the Chef server. Consequently, purging a cookbook will disable any other
cookbook that references one or more files from a cookbook that has been purged.

Examples

Use a regular expression to define the pattern used to bulk delete cookbooks:

$ knife cookbook bulk delete "^[0-9]{3}$" -p

CREATE


The create argument is used to create a new cookbook directory on the local machine,
including the following directories and files:

· cookbook/attributes

· cookbook/CHANGELOG.md

· cookbook/definitions

· cookbook/files/default

· cookbook/libraries

· cookbook/metadata.rb

· cookbook/providers

· cookbook/README.md (or .rdoc)

· cookbook/recipes/default.rb

· cookbook/resources

· cookbook/templates/default

After the cookbook is created, it can be uploaded to the Chef server using the knife
upload argument.

Syntax

This argument has the following syntax:

$ knife cookbook create COOKBOOK_NAME (options)

Options

This argument has the following options:

-C COPYRIGHT_HOLDER, --copyright COPYRIGHT_HOLDER
The name of the copyright holder. This option will place a copyright notice that
contains the name of the copyright holder in each of the pre-created files. If this
option is not specified, a copyright name of "your_company_name" will be used
instead; it can be easily modified later.

-I LICENSE, --license LICENSE
The type of license under which a cookbook is distributed: apachev2, gplv2, gplv3,
mit, or none (default). This option will place the appropriate license notice in
the pre-created files: Apache v2.0 (for apachev2), GPL v2 (for gplv2), GPL v3 (for
gplv3), MIT (for mit), or license 'Proprietary - All Rights Reserved (for none). Be
aware of the licenses for files inside of a cookbook and be sure to follow any
restrictions they describe.

-m EMAIL, --email EMAIL
The email address for the individual who maintains the cookbook. This option will
place an email address in each of the pre-created files. If this option is not
specified, an email name of "your_email" will be used instead; it can be easily
modified later.

-o PATH, --cookbook-path PATH
The directory in which cookbooks are created. This can be a colon-separated path.

-r FORMAT, --readme-format FORMAT
The document format of the readme file: md (markdown) and rdoc (Ruby docs).

Examples

To create a cookbook named "my_cookbook" with copyright, email, license, and readme format
options specified, enter:

$ knife cookbook create my_cookbook -C "My Name" -m "[email protected]" -I apachev2 -r md

to return something like:

** Creating cookbook my_cookbook
** Creating README for cookbook: my_cookbook
** Creating metadata for cookbook: my_cookbook

DELETE


The delete argument is used to delete a specified cookbook or cookbook version on the Chef
server (and not locally).

Syntax

This argument has the following syntax:

$ knife cookbook delete COOKBOOK_NAME [COOKBOOK_VERSION] (options)

Options

This argument has the following options:

-a, --all
Use to delete all cookbooks (and cookbook versions).

COOKBOOK_VERSION
The version of a cookbook to be deleted. If a cookbook has only one version, this
option does not need to be specified. If a cookbook has more than one version and
this option is not specified, knife will prompt for a version.

-p, --purge
Use to entirely remove a cookbook (or cookbook version) from the Chef server. This
action should be used carefully because only one copy of any single file is stored
on the Chef server. Consequently, purging a cookbook will disable any other
cookbook that references one or more files from a cookbook that has been purged.

Examples

$ knife cookbook delete cookbook_name version

For example:

$ knife cookbook delete smartmon 0.8

Type Y to confirm a deletion.

TEST


The test argument is used to test a cookbook for syntax errors. This argument uses Ruby
syntax checking to verify every file in a cookbook that ends in .rb and Embedded Ruby
(ERB). This argument will respect .chefignore files when determining which cookbooks to
test for syntax errors.

Syntax

This argument has the following syntax:

$ knife cookbook test COOKBOOK_NAME (options)

Options

This argument has the following options:

-a, --all
Use to test all cookbooks.

-o PATH:PATH, --cookbook-path PATH:PATH
The directory in which cookbooks are created. This can be a colon-separated path.

Examples

$ knife cookbook test cookbook_name

UPLOAD


The upload argument is used to upload one or more cookbooks (and any files that are
associated with those cookbooks) from a local repository to the Chef server. Only files
that do not already exist on the Chef server will be uploaded.

NOTE:
Use a .chefignore file to prevent the upload of specific files and file types, such as
temporary files or files placed in folders by version control systems. The .chefignore
file must be located in the root of the cookbook repository and must use rules similar
to filename globbing (as defined by the Ruby File.fnmatch syntax).

NOTE:
Empty directories are not uploaded to the Chef server. To upload an empty directory,
create a "dot" file---e.g. .keep---in that directory to ensure that the directory
itself is not empty.

Syntax

This argument has the following syntax:

$ knife cookbook upload [COOKBOOK_NAME...] (options)

Options

This argument has the following options:

-a, --all
Use to upload all cookbooks.

--concurrency
The number of allowed concurrent connections. Default: 10.

-d, --include-dependencies
Use to ensure that when a cookbook has a dependency on one (or more) cookbooks,
those cookbooks will also be uploaded.

-E ENVIRONMENT, --environment ENVIRONMENT
Use to set the environment version dependency to the cookbook version being
uploaded.

--force
Use to update a cookbook even if the --freeze flag has been set.

--freeze
Use to require changes to a cookbook be included as a new version. Only the --force
option can override this setting.

-o PATH:PATH, --cookbook-path PATH:PATH
The directory in which cookbooks are created. This can be a colon-separated path.

Examples

$ knife cookbook upload cookbook_name

To upload a cookbook, and then prevent other users from being able to make changes to it,
enter:

$ knife cookbook upload redis --freeze

to return something like:

Uploading redis...
Upload completed

If a cookbook is frozen and the --force option is not specified, knife will return an
error message similar to the following:

Uploading redis...
ERROR: Version 0.1.6 of cookbook redis is frozen. Use --force to override.
