How to write Sentinel policies

@hcrhall I found your response here very helpful. May I know if we have other sentinel policy examples too.

Sentinel policy to check VM agents getting deployed using custom-data/user-data

Hi @jhabikal21, I’m sure the implementation between the two cloud providers vary but here is an example of how you could use the base64 import to decode the value of the custom_data that has been supplied in the terraform configuration. Then it’s a case of performing some regex magic to look for unsupported configuration. I’m not sure if this is the best way of doing it, but it may give you some ideas.
