Hello, many thanks for your question, on the cluster creation template there is an optional setting called policy_id, this id can be retrieved from the UI, if you go under Compute > Policies > Select the policy you want to set.

By default if the user you are using to create the cluster has Unrestricted cluster creation entitlement then all clusters will be created with it.

thank you so much for your help, I have a question regarding the use of policy IDs in the configuration of Databricks clusters. I'm curious to know whether policy IDs are static or subject to change. Specifically, I'm interested in understanding if policy IDs remain constant once assigned or if they can change over time. Could you please clarify this for me?

The policy id will persist, it is tied to the configuration you have set, even if changing the configuration of a custom policy it will persist with same policy id
