The .NET SDK enables generating container images and pushing them to a registry. These instructions are part of a container workshop, which details fundamental workflows for using .NET in containers.

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 -t:PublishContainer -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
