potiuk opened a new pull request #14819:
URL: https://github.com/apache/airflow/pull/14819


   Docker introduced rate limits for image pulls:
   
   https://www.docker.com/increase-rate-limits
   
   We are using a number of images which we do not have to build
   ourselves and used them from official images such as mongo or
   rabbit or cassndra, postgres, mysql, but we started to hit the limits
   where a lot of builds are run in quick succession (with #14531 it will
   become even worse because our builds will run faster).
   
   Therefore we pushed the images to apache/airflow-* prefixed
   images - apache/* images are exempted from pull rate limit.
   
   Example failed build:

   Pulling postgres (postgres:13)...
