NAME

       knife-data-bag - Store arbitrary data on a Chef Server

SYNOPSIS

       knife data bag sub-command (options)

DESCRIPTION

       Data  bags  are stores of arbitrary JSON data. Each data bag is a collection that may contain many items. Data Bag Items are indexed by the
       Chef Server and can be searched via knife-search(1).

       Data bags are available to all nodes configured by chef-client(8), and are therefore a convenient mechanism to  store  global  information,
       such as lists of administrative accounts that should be configured on all hosts.

DATA BAG SUB-COMMANDS
CREATE

       knife data bag create bag name [item id] (options)

       -s, --secret SECRET
	      A secret key used to encrypt the data bag item. See encryption support below.

       --secret-file SECRET_FILE
	      The path to a file containing the secret key to be used to encrypt the data bag item.

       If  item  id  is given, creates a new, empty data bag item and opens it for editing in your editor. The data bag will be created if it does
       not exist.

       If item id is not given, the data bag will be created.

DELETE

       knife data bag delete bag name [item id] (options)

       Delete a data bag, or an item from a data bag.

EDIT

       knife data bag edit bag name item id (options)

       -s, --secret SECRET
	      A secret key used to encrypt the data bag item. See encryption support below.

       --secret-file SECRET_FILE
	      The path to a file containing the secret key to be used to encrypt the data bag item.

       Edit an item in a data bag.

FROM FILE

       knife data bag from file bag name file (options)

       knife data bag from file bag name file1 file2 file3 (options)

       knife data bag from file bag name folder (options)

       -s, --secret SECRET
	      A secret key used to encrypt the data bag item. See encryption support below.

       --secret-file SECRET_FILE
	      The path to a file containing the secret key to be used to encrypt the data bag item.

       Load a data bag item from a JSON file. If file is a relative or absolute path to the file, that file will  be  used.  Otherwise,  the  file
       parameter  is  treated  as  the	base  name  of	a  data  bag  file  in	a  Chef  repository,  and  knife  will	search	for  the  file	in
       ./data_bags/bag_name/file. For example knife data bag from file users dan.json would attempt to load the file ./data_bags/users/dan.json.

LIST

       knife data bag list (options)

       -w, --with-uri
	      Show corresponding URIs

       Lists the data bags that exist on the Chef Server.

SHOW

       knife data bag show BAG [ITEM] (options)

       -s, --secret SECRET
	      A secret key used to encrypt the data bag item. See encryption support below.

       --secret-file SECRET_FILE
	      The path to a file containing the secret key to be used to encrypt the data bag item.

       Show a specific data bag or an item in a data bag. The output will be formatted according to the --format option.

ENCRYPTION SUPPORT

       Data Bag Items may be encrypted to keep their contents secret. This may be desireable when storing sensitive information such  as  database
       passwords, API keys, etc.

       Data Bag Item encryption uses the AES-256 CBC symmetric key algorithm.

       CAVEATS:  Keys  are not encrypted; only values are encrypted. The "id" of a Data Bag Item is not encrypted, since it is used by Chef Server
       to store the item in its database. For example, given the following data bag item:

	   {"id": "important_passwords", "secret_password": "opensesame"}

       The key "secret_password" will be visible to an evesdropper, but the value "opensesame" will be protected. Both the key "id" and its  value
       "important_passwords" will be visible to an evesdropper.

       Chef Server does not provide a secure mechanism for distributing encryption keys.
