 An example project using this approach can be found here: https://gitlab.com/gitlab-examples/docker.
 
+## 3. Bind Docker socket
+
+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.
+
+In order to do that follow the steps:
+
+1. Install [GitLab Runner](https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/#installation).
+
+1. Register GitLab Runner from the command line to use `docker` and `privileged`
+   mode:
+
+    ```bash
+    sudo gitlab-runner register -n \
+      --url https://gitlab.com/ci \
+      --token RUNNER_TOKEN \
+      --executor docker \
+      --description "My Docker Runner" \
+      --docker-image "docker:latest" \
+      --docker-volumes /var/run/docker.sock:/var/run/docker.sock
+    ```
+
+    The above command will register a new Runner to use the special
+    `docker:latest` image which is provided by Docker. **Notice that it's using
+    the Docker daemon of the runner itself, and any containers spawned by docker commands will be siblings of the runner rather than children of the runner.** This may have complications and limitations that are unsuitable for your workflow.
+
+    The above command will create a `config.toml` entry similar to this:
+
+    ```
+    [[runners]]
+      url = "https://gitlab.com/ci"
+      token = TOKEN
+      executor = "docker"
+      [runners.docker]
+        tls_verify = false
+        image = "docker:latest"
+        privileged = false
+        disable_cache = false
+        volumes = ["/usr/local/bin/docker:/usr/bin/docker", "/cache"]
+      [runners.cache]
+        Insecure = false
+    ```
+
+1. You can now use `docker` from build script (note that you don't need to include the `docker:dind` service as in the option above):
+
+    ```yaml
+    image: docker:latest
+
+    before_script:
+    - docker info
+
+    build:
+      stage: build
+      script:
+      - docker build -t my-docker-image .
+      - docker run my-docker-image /script/to/run/tests
+    ```
+
+1. However, by sharing the docker daemon, you are effectively disabling all
+   the security mechanisms of containers and exposing your host to privilege
+   escalation which can lead to container breakout.
