docker-volumes /var/run/docker.sock:/var/run/docker.sock Register GitLab Runner from the command line to use docker and share /var/run/docker.sock: sudo gitlab-ci-multi-runner register -n \ The third approach is to bind-mount /var/run/docker.sock into the container so that docker is available in the context of that image. To use a different driver, see Using the overlayfs driver.Īn example project using this approach can be found here. By default, docker:dind uses -storage-driver vfs which is the slowest form offered.But this also means jobs can be slower because there's no caching of layers.

Concurrent jobs work fine because every build gets it's own instance of Docker engine so they won't conflict with each other. When using docker-in-docker, each job is in a clean environment without the past history.

For more information, check out the official Docker documentation on Runtime privilege and Linux capabilities.

By enabling -docker-privileged, you are effectively disabling all of the security mechanisms of containers and exposing your host to privilege escalation which can lead to container breakout.

ĭocker-in-Docker works well, and is the recommended configuration, but it is not without its own challenges: Script: - docker build -t my-docker-image.

HOW TO INSTALL GITLAB DOCKER DRIVER

# When using dind, it's wise to use the overlayfs driver for # improved performance. You can now use docker in the build script (note the inclusion of the docker:dind service): image: docker:latest The above command will create a config.toml entry similar to this: ] If you want to use docker-in-docker mode, you always have to use privileged = true in your Docker containers. Notice that it's using the privileged mode to start the build and service containers. The above command will register a new Runner to use the special docker:latest image which is provided by Docker. Register GitLab Runner from the command line to use docker and privileged mode: sudo gitlab-ci-multi-runner register -n \ The second approach is to use the special docker-in-docker (dind) Docker image with all tools installed ( docker and docker-compose) and run the job script in context of that image in privileged mode. For more information please read On Docker security: docker group considered harmful.

HOW TO INSTALL GITLAB DOCKER FULL

By adding gitlab-runner to the docker group you are effectively granting gitlab-runner full root permissions.

You can now use docker command and install docker-compose if needed. docker run my-docker-image /script/to/run/tests gitlab-ci.yml: before_script: - docker infoīuild_image: script: - docker build -t my-docker-image. You can now verify that everything works by adding docker info to. Verify that gitlab-runner has access to Docker: sudo -u gitlab-runner -H docker info

registration-token REGISTRATION_TOKEN \įor more information how to install Docker Engine on different systems checkout the Supported installations.Īdd gitlab-runner user to docker group: sudo usermod -aG docker gitlab-runner GitLab Runner then executes job scripts as the gitlab-runner user.ĭuring GitLab Runner installation select shell as method of executing job scripts or use command: sudo gitlab-ci-multi-runner register -n \ The simplest approach is to install GitLab Runner in shell execution mode. There are three methods to enable the use of docker build and docker run during jobs each with their own tradeoffs.

This requires special configuration of GitLab Runner to enable docker support during jobs. $ docker tag my-image my-registry:5000/my-image $ docker run my-docker-image /script/to/run/tests It's also useful when your application already has the Dockerfile that can be used to create and test an image: $ docker build -t my-image dockerfiles/

deploy to a server from the pushed image.

One of the new trends in Continuous Integration/Deployment is to: This also allows to you to use docker-compose and other docker-enabled tools. GitLab CI allows you to use Docker Engine to build and test docker-based projects.
