Some of the Admin UI functionalities are disabled when Spotfire is deployed in kubernetes or using containers along with marking deployment area as N/A (Externally managed).

Product:TIBCO Spotfire Server
Versions:11.8.1 and higher

Summary:
To avoid weird UI states or UI actions that interfere with the external orchestration system (e.g kubernetes) some of the UI actions are disabled or hidden.

Details:
You may notice that N/A (Externally managed) is assigned as the deployment area text with few missing UI controls such as :

• Upgrade/Rollback
• Restart / Stop / Start etc
• Install / Delete service
• Add/Remove instance
• Edit / Rename

Resolution:
This is by design that we introduced a flag or indication that a Node Manager is "N/A (Externally managed)", a.k.a running in a container by another orchestrator (e.g Kubernetes). 

Also, to avoid confusions/weird UI states certain functionalities in the UI are also hidden/disabled only with the external orchestration system (e.g kubernetes)
