data-bag-merge Cookbook
This cookbook gives you the ability to store environment and node configuration
in data bags (including encrypted ones).
No cookbook would then need changing to support getting credentials from data bag,
as it will be able to read the merged attributes from the data bag.
Encrypting sensitive environment and node configuration is important, as you
shouldn't allow anyone to access this information, including VCS (Version control systems)
The encryption secret key can then be stored elsewhere, and data bags decrypted
by it at the point of chef converge.

Usage
data-bag-merge::environment
Include data-bag-merge::environment
in your node's run_list
at the very top
of the run-list and define the node's environment
{ "name":"my_node", "environment": "production", "run_list": [ "recipe[data-bag-merge::environment]" ] }
This will access the data bag environments/production
, merging it's data into
the node's defaults.
data-bag-merge::node
Include data-bag-merge::node
in your node's run_list
at the very top of the
run-list and define the node's environment
{ "name":"my_node", "environment": "production", "run_list": [ "recipe[data-bag-merge::node]" ] }
This will access the data bag nodes/my_node
, merging it's data into the node's
defaults.
definitions
Chef definitions are provided for additionally providing custom data bag merges
e.g.
encrypted_data_bag_merge "custom" do
data_bag "my-custom-bag"
item 'my-bag-item'
end
