I have Windows 10 Home, so have Docker Toolbox installed, and therefore run my containers on a VirtualBox VM.
This example from the Docker docs worked perfectly:
https://docs.docker.com/get-started/part2/
I set up port forwarding on the VM so that 8000 on localhost mapped to 8080 on the guest machine, fired up the container using
docker container run --rm --detach -p 8000:8080 <image name>
and could access the site by going to 192.168.99.100:8000 in a browser on the host machine, or curl at the command line. No problems whatsoever.
However, whenever I try to put an ASP.NET Core website into a container in the same way, I'm unable to access it, I constantly get a 404.
I assumed that I had something missing in my Dockerfile (even though the image builds successfully), so, to eliminate that, I wanted to try a couple of pre-created images from here:
Again, the console app worked perfectly, but the website again cannot be found (I changed the -p argument to 8000:8080 to match what I have set up).
I'm at a bit of a loss to understand what the problem is here.
