docker-brew is a command-line tool used to build the docker standard library.

Stackbrew

Stackbrew is a web-application that performs continuous building of the docker standard library. See README.md in the stackbrew subfolder for more information.

Library definition files

The library definition files are plain text files found in the library/ subfolder of the stackbrew repository.

File names

The name of a definition file will determine the name of the image(s) it creates. For example, the library/ubuntu file will create images in the <namespace>/ubuntu repository. If multiple instructions are present in a single file, all images are expected to be created under a different tag.

Instruction format

Note: there is no backwards compatibility with the old format. This is part of our effort to create strict, unambiguous references to build images upon.

<docker-tag>:	<git-url>@<git-tag>
2.4.0: 	git://github.com/dotcloud/[email protected]
<docker-tag>:	<git-url>@<git-commit-id>
2.2.0: 	git://github.com/dotcloud/docker-redis@a4bf8923ee4ec566d3ddc212

Stackbrew will fetch data from the provided git repository from the provided reference. Generated image will be tagged as <docker-tag>. If a git tag is removed and added to another commit, you should not expect the image to be rebuilt. Create a new tag and submit a pull request instead.
