I didn't even really realize it was a SPOF in my deploy chain. I figured at least most of it would be cached locally. Nope, can't deploy.

I don't work on mission-critical software (nor do I have anyone to answer to) so it's not the end of the world, but has me wondering what my alternate deployment routes are. Is there a mirror registry with all the same basic images? (node/alpine)

I suppose the fact that I didn't notice before says wonderful things about its reliability.

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.

This is the way tho this can lead to fun moments like I was just setting up a new cluster and couldn't figure out why I was having problems pulling images when the other clusters were pulling just fine.

Took me a while to think of checking the docker hub status page.

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.
