These instructions assume you are running Linux and you have already installed Docker.

You can use the official Gitblit Docker image.

See the Docker Hub Readme for more detailed usage information.

sudo docker pull gitblit/gitblit:rpc
sudo docker run -d --name gitblit -p 8443:8443 -p 8080:8080 -p 9418:9418 -p 29418:29418 gitblit/gitblit:rpc

The followings commands should retrieve and execute the Gitblit image and launch Gitblit in a Docker container that serves the web UI on ports 8080 and 8443. Your repositories will also be accessible via ssh, http, https, and the git procotol. The RPC administration interface has also been enabled so that you may use the Gitblit Manager to configure settings, manage repositories, or manage users.

You should be able to browse to http://localhost:8080 or https://localhost:8443 and login as admin/admin.

You can shutdown your gitblit container with:

sudo docker exec -it gitblit gitblit-stop.sh

You can manually re-start your container with:

sudo docker start gitblit

The Gitblit image stores data under /var/opt/gitblit. A Docker volume is defined for this path, so that data is stored persistently and efficiently. The data is split into a subfolder for configuration data (etc/) and one for repository data (srv/).

The gitblit server is run under the user and group id 8117, assigned to the user gitblit.

You can build your own Gitblit image with the files in this repository.

git clone https://github.com/gitblit/gitblit-docker.git

cd gitblit-docker
sudo docker build -t my-gitblit .

sudo docker run -d --name gitblit -p 8443:8443 -p 8080:8080 -p 9418:9418 -p 29418:29418 my-gitblit

The directory layout for the Gitblit data was changed with the image for version 1.9.0. If you had previously used a Docker image of Gitblit with a volume mounted on /opt/gitblit-data, migration of the configuration data is advised. A script migrate-data is available in the new image for this. Run the script from a container with your volume mounted under /var/opt/gitblit.
