title: Allow pulling of container images using personal access tokens

......@@ -104,12 +104,14 @@ Make sure that your GitLab Runner is configured to allow building Docker images
following the [Using Docker Build](../../ci/docker/using_docker_build.md)
and [Using the GitLab Container Registry documentation](../../ci/docker/using_docker_build.md#using-the-gitlab-container-registry).
## Limitations
## Using with private projects
In order to use a container image from your private project as an `image:` in
your `.gitlab-ci.yml`, you have to follow the
[Using a private Docker Registry][private-docker]
documentation. This workflow will be simplified in the future.
If a project is private, credentials will need to be provided for authorization.
The preferred way to do this, is by using personal access tokens, which can be
created under `/profile/personal_access_tokens`. The minimal scope needed is:
`read_registry`.
This feature was introduced in GitLab 9.3.
