Rate Limiting by the Numbers

Category: Software, Docker, automation

As a critical part of Docker’s transition into sustainability, we’ve been gradually rolling out limits on docker pulls to the heaviest users of Docker Hub. We also shared that “roughly 30% of all downloads on Hub come from only 1% of our anonymous users,” illustrated in this chart: This shows the dramatic impact that a very small percentage of anonymous, free users have on all of Docker Hub.

Those developers rely upon us to save and share their own container images, as well as to pull images from Docker Verified Publishers and our own trusted library of Docker Official Images, amounting to more than 13.6 billion pulls per month.

We’ve put a few things in place to ease the transition for anyone affected: On Wednesday, November 18, we expect to complete our progressive rollout to the new limits of 100 pulls and 200 pulls per 6-hour window for anonymous and authenticated free users, respectively. At that point, anyone who has not yet encountered the limits can reasonably conclude that their current usage of docker pulls is in that 98.5% of unaffected Docker Hub users.
