kpromo: CLI that promotes container images from staging to prod registries for Kubernetes releases—signs, mirrors, attests provenance.

Does the kpromo rewrite affect my Kubernetes cluster?

Indirectly yes—faster, reliable image pulls from registry.k8s.io. No user changes needed.

Is kpromo open source?

Yep, in kubernetes-sigs/promo-tools. Grab v4.4.0+ for the new pipeline.
