Disable ability to choose PHOTON

noorbasha534 — Tue, 18 Mar 2025 13:12:08 GMT

Dear all,

as an administrator, I want to restrict developers from choosing 'photon' option in job clusters. I see this in the job definition when they choose it -

"runtime_engine": "PHOTON"

How can I pass this as input in the policy and restrict developers from using photon...

Thank you for the guidance..

Br,

Noor.

Hi @noorbasha534 ,

To restrict developers from selecting Photon in job clusters, you need to define a cluster policy that enforces constraints on the "runtime_engine" field.

{ "runtime_engine": { "type": "fixed", "value": "STANDARD", "hidden": true } }

•The "type": "fixed" ensures that users cannot modify this value.
• The "value": "STANDARD" forces clusters to only use the Standard runtime, effectively blocking Photon.
•The "hidden": true prevents developers from even seeing this option in the UI.

“I created a new policy called ‘test’ to verify the restrictions, and as you can see, the option doesn’t appear in the menu! 🙂 “ (Without hidden It will appear but you cant select it)

Hope this helps 🙂

You also need to make sure the policy permissions are set up properly. You can/should fix preexisting compute affected by the policy with the wizard in the policy edit screen.
