nbering/git-archive repository overview

⁠Git Archive

Make a tarball out of a GitHub repo over SSH.

⁠Why?

GitHub doesn't support git archive --remote, and while you can get a tarball of a pulic repo from a URL, getting one for a private repo requires api tokens.

I just needed a way to make a tarball of a git repo in a containerized build workflow... so this fills that need.

⁠Usage

Expects a repository as an command argument, ie.

[email protected]:docker/docker-ce.git

Because of some internal implementation details, .git at is assumed to be in the input.

docker run --rm -it -v $PWD/tmp:/output nbering/git-archive [email protected]:docker/docker-ce.git

• --rm - auto-remove container after exit
• -it - attach to the terminal as an interactive session (helpful if there's any prompts)
• -v $PWD/tmp:/output - /output inside the container is where the archive will be placed. This mounts ./tmp to that directory to capture the output.
• nbering/git-archive - The image name.
• [email protected]:docker/docker-ce.git - The repo to capture as an archive. Must end in .git.

Since this is more-or-less assumed to be for private github repos that you have an SSH key for... mount an SSH key into the container with:

-v $HOME/.ssh/github_rsa:/root/.ssh/id_rsa:ro

This would produce a tarball of the docker-ce repo at ./tmp/docker-ce.tar.gz.
