Create app

Create an app.

$ mkdir webapp
$ cd webapp
$ dotnet new web

Login to the container registry

By default, the .NET SDK reads the same credentials as Docker Desktop.

The following pattern is used, for Docker Hub:

$ docker login -u richlander

Publish image

The following properities (as demonstrated in the following command) can be used to build and push an image to a registry.

$ dotnet publish -p PublishProfile=DefaultContainer -p ContainerRepository=richlander/webapp -p ContainerRegistry=docker.io

We can then validate that presence of the image in the target registry.

$ docker pull richlander/webapp
