Dependency Proxy (PREMIUM)

Introduced in GitLab Premium 11.11.

NOTE: Note: This is the user guide. In order to use the dependency proxy, an administrator must first configure it.

For many organizations, it is desirable to have a local proxy for frequently used upstream images/packages. In the case of CI/CD, the proxy is responsible for receiving a request and returning the upstream image from a registry, acting as a pull-through cache.

The dependency proxy is available in the group level. To access it, navigate to a group's Overview > Dependency Proxy.

Using the Docker dependency proxy

With the Docker dependency proxy, you can use GitLab as a source for a Docker image. To get a Docker image into the dependency proxy:

  1. Find the proxy URL on your group's page under Overview > Dependency Proxy, for example

  2. Trigger GitLab to pull the Docker image you want (e.g., alpine:latest or linuxserver/nextcloud:latest) and store it in the proxy storage by using one of the following ways:

    • Manually pulling the Docker image:

      docker pull
    • From a Dockerfile:

    • In .gitlab-ci.yml:


GitLab will then pull the Docker image from Docker Hub and will cache the blobs on the GitLab server. The next time you pull the same image, it will get the latest information about the image from Docker Hub but will serve the existing blobs from GitLab.

The blobs are kept forever, and there is no hard limit on how much data can be stored.


The following limitations apply:

  • Only public groups are supported (authentication is not supported yet).
  • Only Docker Hub is supported.
  • This feature requires Docker Hub being available.
