Data Bags - Learning Chef - page 280

To create data bag items, use the knife data_bag from file command. knife data_bag
from file assumes that the .json files are in a subdirectory with the specified data bag name
under the directory data_bags :
$ knife data_bag from file users alice.json
Updated data_bag_item[users::alice]
$ knife data_bag from file users bob.json
Updated data_bag_item[users::bob]
To search data bags, use the name of the data bag in the index parameter to knife search .
In this case, our data bag name is users “:” . The following command will search for the list
of users we created in a data bag:
$ knife search users "*:*"
2 items found
chef_type: data_bag_item
comment: Alice Jones
data_bag: users
gid: 0
home: /home/alice
id: alice
shell: /bin/bash
uid: 2000
chef_type: data_bag_item
comment: Bob Smith
data_bag: users
gid: 0
home: /home/bob
id: bob
shell: /bin/bash
uid: 2001
You can add specific key-value pairs in the query part of the knife search command line.
The following query will return the item where id == alice :
$ knife search users "id:alice"
1 items found
chef_type: data_bag_item
