kube-image-keeper kuik, https://github.com/enix/kube-image-keeper makes sure that your workloads keep starting even when the upstream registry is down, Docker Hub rate-limits you, or an image tag gets deleted. It’s an open-source Kubernetes image resiliency solution that provides transparent image routing across multiple registries, as well as selective caching and replication of the images used by your workloads into local or external registries. On 100+ production clusters it has saved us countless incidents during registry outages and rate-limit storms, and made node autoscaling actually reliable. The talk covers the concrete usecases it solves, what we got wrong in v1, why we rewrote it as v2, and the edge cases that bit us along the way: mutating webhooks, garbage collection, and keeping the cache honest at scale.
