git-sync

git-sync is a command that pull a git repository to a local directory.

It can be used to source a container volume with the content of a git repo.

In order to ensure that the git repository content is cloned and updated atomically, you cannot use a volume root directory as the directory for your local repository.

The local repository is created in a subdirectory of /git, with the subdirectory name specified by GIT_SYNC_DEST.

Usage

# build the container
docker build -t yourname/git-sync .
# or
make container

# run the git-sync container
docker run -d \
    -e GIT_SYNC_REPO=https://github.com/kubernetes/kubernetes \
    -e GIT_SYNC_DEST=/git \
    -e GIT_SYNC_BRANCH=gh-pages \
    -v /git-data:/git \
    git-sync
# run a nginx container to serve sync'ed content
docker run -d -p 8080:80 -v /git-data:/usr/share/nginx/html nginx
