Move legacy apps to Windows Containers
summary
Migrates dozens of IIS sites including Classic ASP and ActiveX into a Windows Server 2016 container, using a Dockerfile that installs IIS features, registers VB6 DLLs and runs ServiceMonitor, then builds locally and runs with docker build → docker run → docker exec to debug until the ActiveX page works. Pushes images to Azure Container Registry to AKS and uses Kubernetes deployments. Notes image sizes (.NET Core Linux ~82 MB, Nano ~200 MB, Server Core ~5 GB) and shows GMSA as the solution for Windows auth.
