From 92b17b10bad1f1788419b70db5d6ed9cdf8d15ef Mon Sep 17 00:00:00 2001 From: Dennis Chen Date: Mon, 9 Apr 2018 10:33:42 +0000 Subject: Dockerbuilder: use the arch info from base image Currently we hardcode the architecture to the `runtime.GOARCH` when building a docker image, this will result in a confusing info if the arch in the base image is different from the one on the host. This PR takes use of the arch data from the base image during the build process, thus we can get consistent arch info between the base image and the finally built image.
