# This script builds various binary artifacts from a checkout of the docker
|
|
# source code.
|
|
#
|
|
# Requirements:
|
|
# - The current directory should be a checkout of the docker source code
|
|
# (http://github.com/docker/docker). Whatever version is checked out
|
|
# will be built.
|
|
# - The VERSION file, at the root of the repository, should exist, and
|
|
# will be used as Docker binary version and package version.
|
|
# - The hash of the git commit will also be included in the Docker binary,
|
|
# with the suffix -dirty if the repository isn't clean.
|
|
# - The script is intented to be run inside the docker container specified
|
|
# in the Dockerfile at the root of the source. 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.
