A sidecar app which clones a git repo and keeps it in sync with the upstream.
Clone or download
thockin Clean up failed clones
If an initial clone crashes, it can leave the git-root in a bad state
such that git can't retry the clone.  This change forces it to clean up
the mess and retry.

git-sync is a simple command that pulls a git repository into a local directory. It is a perfect "sidecar" container in Kubernetes - it can periodically pull files down from a repository so that an application can consume them.

git-sync can pull one time, or on a regular interval. It can pull from the HEAD of a branch, or from a git tag, or from a specific git hash. It will only re-pull if the target of the run has changed in the upstream repository. When it re-pulls, it updates the destination directory atomically. In order to do this, it uses a git worktree in a subdirectory of the --root and flips a symlink.


# build the container
make container REGISTRY=registry VERSION=tag

# run the container
docker run -d \
    -v /tmp/git-data:/git \
    registry/git-sync:tag \

# run an nginx container to serve the content
docker run -d \
    -p 8080:80 \
    -v /tmp/git-data:/usr/share/nginx/html \
