What is kuik?

Section titled “What is kuik?”

✅ Its primary objective is to maximize the availability of Pod images strictly within the Kubernetes cluster it runs on.

✅ Its secondary goal is to ensure bulletproof reliability by keeping the manipulation of Kubernetes primitives to an absolute minimum.

Under the hood

Section titled “Under the hood”

It relies on three core mechanisms:

  • Image routing: rewrites Pod image paths on the fly during their creation to redirect them to a functional registry.
  • Image copy: mirror images used by the local cluster accross registries, building a virtual, highly available registry.
  • Image monitoring: continuously tracks the availability of Pod images used within the local cluster across various registries.

Note : image routing is performed at Pod creation by a lightweight MutatingWebhook that automatically rewrites the image path whenever the source registry becomes unavailable.

Developed by Enix, kube-image-keeper is a battle-tested solution currently running in production across multiple Kubernetes clusters.
