How to run a .net core web api locally on Docker?-CodePudding

I've created a web api that I can run locally in Visual Studio on localhost and I can access Swagger via. http://localhost:5000/swagger/index.html.

I've created a Dockerfile and executed docker build -t test . and I can see the image created in Docker Desktop. When running it, I don't get any error and I get these logs:

=info: Microsoft.Hosting.Lifetime[14]

      Now listening on: http://[::]:80

info: Microsoft.Hosting.Lifetime[0]

      Application started. Press Ctrl C to shut down.

info: Microsoft.Hosting.Lifetime[0]

      Hosting environment: Production

info: Microsoft.Hosting.Lifetime[0]

      Content root path: /app

What do I need to do to make the web api accessible via. a browser?

Microsoft set the environment variable ASPNETCORE_URLS to http:// :80 in their base images, so your app is listening on port 80 when it runs in a container.

You should also be aware that Swagger normally isn't available in a container, because Swagger by default only is available when running in development environments. A container is not considered development by default.

So to run your container and have access to Swagger, you should run your container using a command that looks something like

docker run --rm -d -e ASPNETCORE_ENVIRONMENT=Development -p 5000:80 test

You should then be able to access your webapi on http://localhost:5000/ and have Swagger available.
