Dockerhub has painful rate limits, that necessitate the use of the registry mirror to use the image in production. They also have very dubious reliability.

They also have some dubious practices. For instance publishing images as "official" when they haven't been endorsed by package maintainers, with official meaning the image officially endorsed by dockerhub.

They even at one point planned to sunset their free team plan before backing out after community backlash: https://www.docker.com/blog/no-longer-sunsetting-the-free-team-plan/

This would have required open source projects to share passwords essentially, or else go through the burden of registering for docker's open source program with no guarantee of timely acceptance: https://www.docker.com/community/open-source/application/

Would recommend instead:

• Google Container Registry
• Github Container Reigstry
• Quay.io
