knife data bag from file - show what changed

Question

When uploading a data bag to chef client is it possible to see what has changed, or what the difference is between a local file and the server?

Answer 1

You should use the knife diff command.

Answer 2

To view what is currently on the server:

knife data bag show <name> <data bag id> --secret-file <path_to_key>

You can drop the secret-file portion if you're not encrypting your passwords. If you want to drop it out to a json file so you can do the diff yourself it's:

knife data bag show <name> <data bag id> --format json --secret-file <path_to_key> > /tmp/data_bag_contents.json
