| # - The current directory should be a checkout of the docker source code |
| # (http://github.com/dotcloud/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 container image. |
