Microsoft IIS Service Monitor

ServiceMonitor is a Windows executable designed to be used as the entrypoint process when running IIS inside a Windows Server container.

ServiceMonitor monitors the status of the w3svc service and will exit when the service state changes from SERVICE_RUNNING to either one of SERVICE_STOPPED, SERVICE_STOP_PENDING, SERVICE_PAUSED or SERVICE_PAUSE_PENDING.

Additionally, ServiceMonitor will promote environment variables from process environment it's own process environment block to the DefaultAppPool. We achieve this by naively copying all variables in our process environment block except for those Environment variable / value pairs present in this list below.

ServiceMonitor is currently distributed as part of the IIS, ASP.NET, and WCF images on Docker Hub. We recommend layering your project on top of those official images as running ServiceMonitor directly in your Dockerfile.
