Evaluate and Migrate Warewolf Docker Image to Windows Server 2022 Base

Sai Chawan 4 dag geleden in Azure 0

The current Docker image for the Warewolf application is based on Windows Server 2019 (ltsc2019) with the following characteristics:

  • OS Version: 10.0.17763.6659

  • Architecture: amd64

  • Image Size (Uncompressed): ~7.06 GB

  • Includes: Warewolf server, PowerShell-based entry point script

  • Base Image: mcr.microsoft.com/windows/servercore:ltsc2019

Due to the use of the Windows Server 2019 servercore base image, the resulting image is relatively large. However, Windows Server 2022 introduces significant improvements that justify a migration:

 Benefits of Migrating to Windows Server 2022:

  • Reduced base image size (~700 MB smaller)

  • Faster container startup times

  • Improved runtime and networking performance


Estimated Image Size Impact:
Layer/ComponentWS 2019 SizeWS 2022 Size
servercore base layer~3.47 GB~2.76 GB
Warewolf + Additions~3.5–4.0 GB~3.0–3.5 GB
Total Image Size~7.0 GB~6.0 GB

Estimated reduction: ~1 GB or ~15–20% smaller overall image size.
