NAME

knife: - Chef server REST API utility

SYNOPSIS

knife sub-command (options)

DESCRIPTION

This manual page documents knife, a command-line utility used to interact with a Chef server directly through the RESTful API. Knife uses sub-commands to take various actions on different types of Chef objects. Some sub-commands take additional options. General options follow sub-commands and their options. A configuration file can be created for common defaults.
Unless otherwise specified, output is in JSON format, and input files are also JSON format.

Chef Server URL
-k, --key KEY
API Client Key
-c, --config CONFIG

-l, --log_level LEVEL
Set the log level (debug, info, warn, error, fatal)
-L, --logfile LOGLOCATION

-u, --user USER
API Client Username
-p, --print-after

-v, --version

SUB-COMMANDS

Knife sub-commands are structured as "NOUN verb NOUN (options)". The sub-commands are meant to be intuitively named.

CLIENT SUB-COMMANDS

Sub-commands related to working with clients, which are registered entities that access the Chef server.
client bulk delete (options)
-r, --regex [REGEX]
Narrow the operation via regular expression

client show CLIENT (options)

-a, --attribute [ATTR]

COOKBOOK SUB-COMMANDS

Cookbooks are the fundamental unit of distribution in Chef. They encapsulate all the recipes of resources and the assets used to configure a particular aspect of the infrastructure.

-f, --fqdn FQDN
The FQDN of the host to see the file for
-p, --platform PLATFORM

-o, --cookbook-path PATH:PATH

List the available data bags.

data bag show BAG [ITEM] (options)

NODE SUB-COMMANDS

Nodes are the entities which are configured with Chef, typically servers or workstations. Nodes are registered as a client, typcially of the same name, but a single client might represent one or more nodes.

node show NODE (options)

-a, --attribute [ATTR]
Show only one attribute
-r, --run-list

ROLE SUB-COMMANDS

Roles provide a mechanism to apply a set of recipes and attributes to nodes. For example, the 'webserver' role might instruct Chef to add a recipe for Apache, and specify a default domain to use.

role bulk delete (options)

-r, --regex [REGEX]

GENERAL SUB-COMMANDS

The following are general sub-commands that do not fit within the other object types used in Chef.

configure (options)

Create a configuration file for knife. This will prompt for values to enter into the file. See "CONFIGURATION" below for available options.

ec2 instance data [RUN LIST...] (options)

Chef is commonly used with Amazon AWS EC2 nodes. This command will generate instance metadata that can be used to automatically configure an EC2 instance with Chef.

Search indexes are a powerful feature of the Chef server and the search subcommand allows searching any of the available indexes using the SOLR query syntax.
