Description

The public preview of Confidential Containers on AKS will be shutting down.

This feature has been available in preview since 2023, and as part of our commitment to delivering secure and reliable services, we are streamlining our confidential computing offerings to focus on supported and production-ready solutions.   
   
What this means for you:  

  • Existing node pools using KataCcIsolation will continue to operate until March 2, 2026. 

  • After March 2, 2026, Confidential Container functionality will no longer be supported, and new node pools using this runtime cannot be created. 

Please refer to the Confidential Containers preview page for more details, or raise an issue in the AKS GitHub.
