Caching Docker images to reduce the number of calls to DockerHub

Caching Docker images to reduce the number of calls to DockerHub

Caching Docker images to reduce the number of calls to DockerHub from your CI/CD infrastructure. Docker announced it will be rate-limiting the number of pull requests to the service in its free plan.

On Aug. 24, 2020, Docker announced changes to its subscription model and a move to consumption-based limits. These rate limits for Docker pulls of container images go into effect on Nov. 1, 2020. For pull requests by anonymous users, this limit is now 100 pull requests per six hours; authenticated users have a limit of 200 pull requests per six hours.

As members of the global DevOps community, we have all come to rely on Docker as an integral part of CI/CD processes. So it is with no surprise that at GitLab, we have heard from several community members and customers seeking guidance on how the Docker rate limit change may affect their production CI/CD workflows.

Use a registry mirror

You can use the Registry Mirror feature to the number of image pull requests generated against DockerHub. When the mirror is configured and GitLab Runner instructs Docker to pull images, Docker will check the mirror first; if it's the first time the image is being pulled, a connection will be made to DockerHub. Subsequent pulls of that image will then use your mirror instead of connecting to DockerHub. More details on how it works can be found here.
