The daemon is available with # a network connection instead of the default /var/run/docker.sock socket. Image : docker:20.10.16 variables : # When using dind service, you must instruct docker to talk with the # daemon started inside of the service. Sometimes you might have legitimate reasons to disable TLS.įor example, you have no control over the GitLab Runner configurationĪssuming that the runner’s config.toml is similar to: docker run my-docker-image /script/to/run/tests Docker-in-Docker with TLS disabled in the Docker executor Docker # creates them automatically on boot, and creates # `/certs/client` to share between the service and job # container, thanks to volume mount from config.toml DOCKER_TLS_CERTDIR : " /certs" services : - docker:20.10.16-dind before_script : - docker info build : stage : build script : - docker build -t my-docker-image. # Specify to Docker where to create the certificates. Docker 19.03 does this automatically # by setting the DOCKER_HOST in # The 'docker' hostname is the alias of the service container as described at #. The daemon is available # with a network connection instead of the default # /var/run/docker.sock socket. Image : docker:20.10.16 variables : # When you use the dind service, you must instruct Docker to talk with # the daemon started inside of the service. Docker-in-Docker with TLS enabled in the Docker executor You can use the Docker executor to run jobs in a Docker container. Use the Docker executor with Docker-in-Docker Unpredictable behavior can result, especially when new versions are released. If you use a tag like docker:stable, you have no control over which version is used. You should always specify a specific version of the image, like docker:20.10.16. We recommend you use Docker-in-Docker with TLS enabled, The job script in context of the image in privileged mode. The Docker image has all of the docker tools installed and can run The executor uses a container image of Docker, provided.Your registered runner uses the Docker executor or the Kubernetes executor.When you add gitlab-runner to the docker group, you are effectively granting gitlab-runner full root permissions.įor more information, see the security of the docker group. You can now use docker commands (and install docker-compose if needed). docker run my-docker-image /script/to/run/tests The Docker commands, but needs permission to do so.īefore_script : - docker info build_image : script : - docker build -t my-docker-image. In this configuration, the gitlab-runner user runs To include Docker commands in your CI/CD jobs, you can configure your runner to Docker socket binding Use the shell executor.To enable Docker commands for your CI/CD jobs, you can use: Enable Docker commands in your CI/CD jobs If you want to build Docker images without enabling privileged mode on the runner, GitLab Runner to support docker commands. To run Docker commands in your CI/CD jobs, you must configure Test it, and publish it to a container registry. You can use GitLab CI/CD with Docker to create Docker images.įor example, you can create a Docker image of your application,
