It seems like pulling image from DockerHub is not possible right now. I'm greeted by a 500. It's not officially acknowledged but sites like https://statusgator.com/services/docker have already detected it.
A lot of people are complaining in <a href="https://isdown.app/status/docker/docker-hub-registry" rel="nofollow">https://isdown.app/status/docker/docker-hub-registry</a> as well.
This is likely related to the Cloudflare R2 outage: <a href="https://news.ycombinator.com/item?id=42960265">https://news.ycombinator.com/item?id=42960265</a>
