I got some solutions from this website: https://github.com/Microsoft/aspnet-docker/issues/64 but didn't help with my error

Thank you in advance for your help!! Note!!!: i'm a beginner

Answer 1

I faced similar issue n had almost similar dockerfile.
To troubleshoot I changed the entrypoint to continuous ping to local host. So that I could login to container n check the issue with w3svc.

I found strange multiple events in event viewer (need to view in powershell) that w3svc is started successfully. There were no stop event. But I concluded that something wrong with my service.

I further checked n found that app pool is in "OnDemand" state instead of "always running". I set the apppool property to always running in my dockerfile. Post that switched entrypoint to original value "service monitor.exe w3svc" n it made my container stable. Note - I m not using default iis image where service monitor already set as entrypoint.
