Question - How does the service fabric windowscore container image actually work?

[andradf]

I'm trying to containerize some SF applications that host reliable services. They are .net 4.6 applications targetting SF 6.4. I've followed the guide on here https://docs.microsoft.com/en-us/azure/service-fabric/service-fabric-services-inside-containers but any application I try to load fails to load any of the service fabric runtime dependencies. I try to find what exactly the recommended container image (microsoft/service-fabric-reliableservices-windowsservercore) has in it and for the life of me I can't find where the service fabric runtime is loaded. All the Dockerfile does is run InstallPreReq.ps1 and then add "C:\sffabricbin" to the system path. The ps1 seems to only install visual c redistributables and dotnet core 2.0.0. So, my question is where does C:\sffabricbin come from? If I execute a dir in the container there is no C:\sffabricbin folder, where I imagine the service fabric runtime is supposed to be.
