## Define an image from a private Docker registry
-Starting with GitLab Runner 0.6.0, you are able to define images located to
-private registries that could also require authentication.
-
-All you have to do is be explicit on the image definition in `.gitlab-ci.yml`.
-
-```yaml
-image: my.registry.tld:5000/namespace/image:tag
-```
-
-In the example above, GitLab Runner will look at `my.registry.tld:5000` for the
-image `namespace/image:tag`.
-
-If the repository is private you need to authenticate your GitLab Runner in the
-registry. Learn how to do that on
-[GitLab Runner's documentation][runner-priv-reg].
+> **Notes:**
+- This feature requires GitLab Runner **1.8** or higher
+- For GitLab Runner versions **>= 0.6, <1.8** there was a partial
+ support for using private registries, which required manual configuration
+ of credentials on runner's host. We recommend to upgrade your Runner to
+ at least version **1.8** if you want to use private registries.
+- If the repository is private you need to authenticate your GitLab Runner in the
+ registry. Learn more about how [GitLab Runner works in this case][runner-priv-reg].
+
+As an example, let's assume that you want to use the `registry.example.com/private/image:latest`
+image which is private and requires you to login into a private container registry.
+To configure access for `registry.example.com`, follow these steps:
+
+1. Do a `docker login` on your computer:
+
+ ```bash
+ docker login registry.example.com --username my_username --password my_password
+ ```
+
+1. Copy the content of `~/.docker/config.json`
+1. Create a [secret variable] `DOCKER_AUTH_CONFIG` with the content of the
+ Docker configuration file as the value:
+
+ ```json
+ {
+ "auths": {
+ "registry.example.com": {
+ "auth": "bXlfdXNlcm5hbWU6bXlfcGFzc3dvcmQ="
+ }
+ }
+ }
+ ```
+
+1. Do a `docker logout` on your computer if you don't need access to the
+ registry from it:
+
+ ```bash
+ docker logout registry.example.com
+ ```
+
+1. You can now use any private image from `registry.example.com` defined in
+ `image` and/or `services` in your [`.gitlab-ci.yml` file][yaml-priv-reg]:
+
+ ```yaml
+ image: my.registry.tld:5000/namespace/image:tag
+ ```
+
+ In the example above, GitLab Runner will look at `my.registry.tld:5000` for the
+ image `namespace/image:tag`.
+
+You can add configuration for as many registries as you want, adding more
+registries to the `"auths"` hash as described above.
