1) The reference mentioned in the answet no longer exists. The closest resource I've found is: https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/docker/building-net-docker-images?view=aspnetcore-3.1#build-and-deploy-manually 2) The source image name might also have changed 3) According to the dockerfile reference (https://docs.docker.com/engine/reference/builder/#environment-replacement), I would expect the environment variable to be placed as $BuildType or ${BuildType}, but there is no such answer

Thanks, another botched question. I would have chosen ${BuildType} as well but it wasn't there so I chose {BuildType}$... which was supposed to be wrong.

Guys, just to confirm what you said: 'Environment variables are notated in the Dockerfile either with $variable_name or ${variable_name}'. Ref: https://docs.docker.com/engine/reference/builder/#environment-replacement
