Tell us about your request

Windows Server 2025 has been out for a while, but ECS-optimized AMIs do not seem to be available yet, which prevents running Windows Server 2025 containers on ECS.

It appears EC2 AMIs were made available in early November, so this request is to follow up with ECS-optimized AMIs and official ECS support. It's probably in progress, but I could not find an existing request.

Which service(s) is this request for?

ECS (non-Fargate in my specific case)

Continue to stick with Windows Server 2022 Core and mcr.microsoft.com/windows/servercore:ltsc2022 based containers.
