[chef]: View all available data bags on a node

Question

In our organization, the devs are being given ownership to own the cookbooks. The cookbooks were initially written by the ops guys. I am a java guy and not a chef/ruby/ops expert. I have been given a task to debug an issue where the cookbook is not reading from the right data-bag.

Is it possible to to list all available data bags on a chef node? I tried something like this but it's taking a long time.

# find / -type f  -not -name "*test*" -exec grep -IHnl data_bag {} \; | grep -v gems

The code I am looking at is:

secret2 = Chef::EncryptedDataBagItem.load_secret(secret)
passwords = data_bag_item(id, item, secret2)

When chef-client runs on a node, does it combine all data_bag json files into 1 data structure. While writing the cookbook, do I have to specify which data_bag to load?

Update:

This command ran very quickly after I limited my search to just chef's directories:

# find /run/chef /opt/chef /var/chef /etc/chef  -type f  -not -name "*test*" -exec grep -IHnl data_bag {} \; | grep -v gems

Answer 1

as you can see in data bags chef documentation and also you specified that you are looking for the code

secret2 = Chef::EncryptedDataBagItem.load_secret(secret)
passwords = data_bag_item(id, item, secret2)

so for your question

While writing the cookbook, do I have to specify which data_bag to load?

the answer is yes. refer to the second line in your snippet, which specifies to load a data bag item named item from a data bag named id and decrept it using secret2 key.

now to your second question:

When chef-client runs on a node, does it combine all data_bag json files into 1 data structure.

from what i know, the answer is no. chef-client fetches a specific data bag from the chef-server on-demand (per what is written in the cookbook).
