Github actions buildx also going down is a really unintended consequence. It would be great if we could mirror away from docker entirely at this point but I digress.

#72Anyone have recommendations for an image cache? Native kubernetes a plus. What would be really nice is a system with mutating admission webhooks for pods which kicks off a job to mirror the image to a local registry and then replaces the image reference with the mirrored location.

#73Well to be fair: this doesn't happen very often. It's quite a stable service in my experience.

#74This is one of the reasons I don't want to use docker on production machines and have started to use systemd again!!
Hard to see if this is /s or not. Nobody is forcing you to run images straight from dockerhub lol. Every host keeps the images already on it. Running a in-house registry is also a good idea.

There's a registry image for OCI containers that is pretty painless to set up and low maintenance, can use s3 as a storage backend.

Your git provider probably also has a container registry service built in.

I guess the best way would be to have a self-hosted pull-through registry with a cache. This way you'd have all required images ready even when dockerhub is offline. Unfortunately that does not help in an outage because you cannot fill the cache now.
In the case where you still have an image locally, trying to build will fail with an error complaining about not being able to load metadata for the image because a HEAD request failed. So, the real question is, why isn't there a way to disable the HEAD request for loading metadata for images? Perhaps there's a way and I don't know it.
Sure? --pull=missing should be the default.

I usually do upstream image mirroring as part of CI. Registries are built into GitLab, AWS (ECR), GitHub, etc

It _is_ pronounced "kway", and it _is_ a real word: https://www.merriam-webster.com/dictionary/quay !
It's pronounced keɪ (from your link - The spelling quay, first appearing in the sixteenth century, follows modern French. As noted by the Oxford English Dictionary, third edition, the expected outcome of Middle English keye would be /keɪ/ in Modern English ). Or key (with modern spelling).
We actually originally pronounced it as "kway" (the American pronunciation we had heard) but then had a saying we'd tell customers (when asked) of "pronounce it however you please, so long as you're happy using it!" :)

We do a local (well, internal) mirror for "all" these things. So, we're basically never stuck. It mirrors our CPAN, NPM, Composer, Docker and other of these web-repos. Helps on the CI tooling as well.
This is the way. At some point it’s way too expensive for a single repo in your supply chain to go down or even pull a package.

Or start a pronunciation revolution and say "kway". It's all made up anyway ;-)

Pronounced "key". The main ferry dock in Sydney is called Circular Quay.
