Docker not hosting anything on the port it says it is, what's going on?

I am working through this blog post which explains how to host a sample ServiceStack app on .net core via Docker.

In the command line I see:

Now listening on: https://*:5000

But as shown in the below screenshot, nothing seems to be hosted on localhost port 5000.

Docker not hosting anything

I have tried this on my Mac and PC and it's the same result.

I am brand new to Docker so I'm assuming this something obvious on my part so apologies for the noob question!

Thanks

By default docker containers do not expose any ports to the world outside of the container. When you start a container, you need to add a port mapping similar to NAT so it can be reached form outside (docs).

When you run docker run you need to pass the port mappings via -p IP:host_port:container_port parameter, i.e. docker run -p 443:5000. Then connect to it via https://localhost (https is on port 443).
