hmmm, I think that you made a small mistake in the kas documentation [1]. You wrote that
http_proxy should be passed as a build-arg but as I said there is no ARG instruction in the
Dockerfile. 

In the meta-iot2000 link you are setting the proxy variables as environment variables using 
'docker run -e http_proxy=$http_proxy'  which does work indeed.
