I am having a basic issue which I haven't been able to explain. Passing arguments to an Azure Pipeline doesn't seem to work. They consistently show as null. I've simplified my Dockerfile as much as possible just for demonstration and it still doesn't work, even with a default value for the ARG. This was originallly part of a Build and Push task which I have separated This originally used an alpine base image but I have switched to Ubuntu I've tried setting different Shells as active This works as expected with a local build of the Dockerfile In all cases the output of the variable is null. Any ideas?
