Synchronise git repository

Keep pulling a git directory for new changes. Intended use is for a containerized application, that is getting its config or content from a git repository. The frontend container shall have a shared volume with this git-sync container. The git-sync container will keep the git repository up to date.

Variables

All configuration is done via environment variables.

Variable	Default value	Description
GIT_SYNC_DIR		(Required) Destination directory inside the container where the repository is cloned to
GIT_SYNC_REPO		(Required) Repository that shall be cloned. If authentication is required, username and password can be included in the url (https://username:[email protected]/user/repo.git)
GIT_SYNC_SLEEP	1	Time in seconds to sleep between the pulls
GIT_SYNC_PULL_OPTS	-f	Options to pass to the git pull command
GIT_SYNC_BRANCH	origin/master	Branch to checkout
GIT_SYNC_NOTEMPTY	false	Per default git only clones into empty directories. If for whatever reason the directory is not empty, set this variable to true to still merge the git repository into the existing directory
GIT_SYNC_NOTEMPTY_OPTS	--mixed	Options to pass to the git reset command, in case there is already content in the directory

Example use

docker run -ti --rm 
    -e GIT_SYNC_DIR=/tmp/mygitdir
    -e GIT_SYNC_REPO=https://github.com/fgierlinger/docker-git-sync 
    git-sync:latest
