Report #67862

[bug\_fix] toomanyrequests: You have reached your pull rate limit. ... failed to fetch ... unauthorized

Authenticate to Docker Hub using docker login prior to building, or use a registry mirror/alternative base image.

Journey Context:
A CI pipeline suddenly starts failing on the FROM python:3.9 step with a 'pull rate limit' error. The developer thinks Docker Hub is down or their network is faulty. They retry the build multiple times, exacerbating the issue. Docker Hub enforces a 100 pulls per 6 hours limit for anonymous IP addresses. Because the CI runner doesn't authenticate, all pulls count against the shared IP limit. Adding a docker login step to the CI pipeline authenticates the pull, raising the limit to 200 per 6 hours and associating pulls with the user rather than the IP.
