NOTE: The official documentation for this topic is updated at https://docs.gitlab.com/ee/ci/docker/using_docker_build.html#use-docker-in-docker-workflow-with-docker-executor. Consider taking a look there as well. --- I'm trying to get the docker in docker build to work. But every time I end up with `Cannot connect to the Docker daemon. Is the docker daemon running on this host?`. I did also try the gitlab/dind:latest. Do I miss anything? Thanks in advance. **config.toml** ``` oncurrent = 1 check_interval = 0 [[runners]] name = "##########" url = "##########" token = "##########" executor = "docker" [runners.docker] tls_verify = false image = "docker:latest" privileged = true disable_cache = false volumes = ["/cache"] [runners.cache] ``` **.gitlab-ci.yml** ``` image: docker:latest # When using dind, it's wise to use the overlayfs driver for # improved performance. variables: DOCKER_DRIVER: overlay services: - docker:dind before_script: - docker info build: script: - docker build -t bla/bla . - docker login -u $DOCKER_USER -p $DOCKER_PASSWORD - docker push ``` **Output:** ``` Running with gitlab-ci-multi-runner 1.8.1 (a2efdd4) Using Docker executor with image docker:latest ...
