+## Extended Docker configuration options
+
+> **Note:**

+
+When configuring the `image` or `services` entries, you can use a string or a map as

+
+- when using a string as an option, it must be the full name of the image to use
+  (including the Registry part if you want to download the image from a Registry
+  other than Docker Hub)
+- when using a map as an option, then it must contain at least the `name`
+  option, which is the same name of the image as used for the string setting
+
+For example, the following two definitions are equal:
+
+1. Using a string as an option to `image` and `services`:

+    image: "registry.example.com/my/image:latest"
+
+    services:
+    - postgresql:9.4
+    - redis:latest
+    ```
+
+1. Using a map as an option to `image` and `services`. The use of `image:name` is
+   required:
+
+    ```yaml
+    image:
+      name: "registry.example.com/my/image:latest"

+
+### Starting multiple services from the same image
+
+Before the new extended Docker configuration options, the following configuration
+would not work properly:
+
+```yaml
+services:
+- mysql:latest
+- mysql:latest
+```
+
+The Runner would start two containers using the `mysql:latest` image, but both
+of them would be added to the job's container with the `mysql` alias based on
+the [default hostname naming](#accessing-the-services). This would end with one
+of the services not being accessible.
+
+After the new extended Docker configuration options, the above example would
+look like:
+
+```yaml
+services:
+- name: mysql:latest
+  alias: mysql-1
+- name: mysql:latest
+  alias: mysql-2
+```
+
+The Runner will still start two containers using the `mysql:latest` image,
+but now each of them will also be accessible with the alias configured
+in `.gitlab-ci.yml` file.
+
+### Setting a command for the service
+
+Let's assume you have a `super/sql:latest` image with some SQL database
+inside it and you would like to use it as a service for your job. Let's also
+assume that this image doesn't start the database process while starting
+the container and the user needs to manually use `/usr/bin/super-sql run` as
+a command to start the database.
+
+Before the new extended Docker configuration options, you would need to create
+your own image based on the `super/sql:latest` image, add the default command,
+and then use it in job's configuration, like:
+
+```Dockerfile
+# my-super-sql:latest image's Dockerfile
+
+FROM super/sql:latest
+CMD ["/usr/bin/super-sql", "run"]
+```
+
+```yaml
+# .gitlab-ci.yml
+
+services:
+- my-super-sql:latest
+```
+
+After the new extended Docker configuration options, you can now simply
+set a `command` in `.gitlab-ci.yml`, like:
+
+```yaml
+# .gitlab-ci.yml
+
+services:
+- name: super/sql:latest
+  command: ["/usr/bin/super-sql", "run"]
+```
+
+As you can see, the syntax of `command` is similar to [Dockerfile's `CMD`][cmd].
+
+### Overriding the entrypoint of an image
+
+Let's assume you have a `super/sql:experimental` image with some SQL database
+inside it and you would like to use it as a base image for your job because you
+want to execute some tests with this database binary. Let's also assume that
+this image is configured with `/usr/bin/super-sql run` as an entrypoint. That
+means, that when starting the container without additional options, it will run
+the database's process, while Runner expects that the image will have no
+entrypoint or at least will start with a shell as its entrypoint.
+
+Previously we would need to create our own image based on the
+`super/sql:experimental` image, set the entrypoint to a shell, and then use
+it in job's configuration, e.g.:
+
+Before the new extended Docker configuration options, you would need to create
+your own image based on the `super/sql:experimental` image, set the entrypoint
+to a shell and then use it in job's configuration, like:
+
+```Dockerfile
+# my-super-sql:experimental image's Dockerfile
+
+FROM super/sql:experimental
+ENTRYPOINT ["/bin/sh"]
+```
+
+```yaml
+# .gitlab-ci.yml
+
+image: my-super-sql:experimental
+```
+
+After the new extended Docker configuration options, you can now simply
+set an `entrypoint` in `.gitlab-ci.yml`, like:
+
+```yaml
+# .gitlab-ci.yml
+
+image:
+  name: super/sql:experimental
+  entrypoint: ["/bin/sh"]
+```
+
+As you can see the syntax of `entrypoint` is similar to
+[Dockerfile's `ENTRYPOINT`][entrypoint].
