In other words: # DO NOT CALL THIS SCRIPT DIRECTLY. # - The right way to call this script is to invoke "make" from # your checkout of the Docker repository. # the Makefile will do a "docker build -t docker ." and then # "docker run hack/make.sh" in the resulting image. # set -o pipefail export DOCKER_PKG='github.com/docker/docker' # We're a nice, sexy, little shell script, and people might try to run us; # but really, they shouldn't.
