Chef-Vault

Gem Version

Build Status

Code Climate

DESCRIPTION:

Gem that allows you to encrypt a Chef Data Bag Item using the public keys of a list of chef nodes. This allows only those chef nodes to decrypt the encrypted values.

For a more detailed explanation of how chef-vault works, please refer to the file THEORY.md

INSTALLATION:

Be sure you are running the latest version Chef. Versions earlier than 0.10.0 don't support plugins:

gem install chef

This plugin is distributed as a Ruby Gem. To install it, run:

gem install chef-vault

Depending on your system's configuration, you may need to run this command with root privileges.

KNIFE COMMANDS:

See KNIFE_EXAMPLES.md for examples of commands

knife.rb

To set 'client' as the default mode, add the following line to the knife.rb file.

knife[:vault_mode] = 'client'

To set the default list of admins for creating and updating vaults, add the following line to the knife.rb file.

knife[:vault_admins] = [ 'example-alice', 'example-bob', 'example-carol' ]

(These values can be overridden on the command line by using -A)

NOTE: chef-vault 1.0 knife commands are not supported! Please use chef-vault 2.0 commands.

Vault

knife vault create VAULT ITEM VALUES
knife vault edit VAULT ITEM
knife vault refresh VAULT ITEM
knife vault update VAULT ITEM VALUES [--clean]
knife vault remove VAULT ITEM VALUES
knife vault delete VAULT ITEM
knife vault rotate keys VAULT ITEM
knife vault rotate all keys
knife vault show VAULT ITEM [VALUES]
knife vault download VAULT ITEM PATH

Global Options:

Short Long Description Default Valid Values Sub-Commands
-M MODE --mode MODE Chef mode to run in. Can be set in knife.rb solo "solo", "client" all
-S SEARCH --search SEARCH Chef Server SOLR Search Of Nodes nil create, remove, update
-A ADMINS --admins ADMINS Chef clients or users to be vault admins, can be comma list nil create, remove, update
-J FILE --json FILE JSON file to be used for values, will be merged with VALUES if VALUES is passed nil create, update
nil --file FILE File that chef-vault should encrypt. It adds "file-content" & "file-name" keys to the vault item nil create, update
-p DATA --print DATA Print extra vault data nil "search", "clients", "admins", "all" show
-F FORMAT --format FORMAT Format for decrypted output summary "summary", "json", "yaml", "pp" show
nil --clean Remove all client keys before re-encrypting with saved or specified search nil nil update
nil --clean-unknown-clients Remove unknown clients during key rotation nil nil remove, rotate

USAGE IN RECIPES

To use this gem in a recipe to decrypt data you must first install the gem via a chef_gem resource. Once the gem is installed require the gem and then you can create a new instance of ChefVault.

NOTE: chef-vault 1.0 style decryption is supported, however it has been deprecated and chef-vault 2.0 decryption should be used instead

Example Code

chef_gem "chef-vault"

require 'chef-vault'

item = ChefVault::Item.load("passwords", "root")
item["password"]

USAGE STAND ALONE

chef-vault can be used as a stand alone binary to decrypt values stored in Chef. It requires that Chef is installed on the system and that you have a valid knife.rb. This is useful if you want to mix chef-vault into non-Chef recipe code, for example some other script where you want to protect a password.

It does still require that the data bag has been encrypted for the user's or client's pem and pushed to the Chef server. It mixes Chef into the gem and uses it to go grab the data bag.

Do chef-vault --help for all available options

Example usage (password)

chef-vault -v passwords -i root -a password -k /etc/chef/knife.rb
