  • Context at https://phabricator.wikimedia.org/T373526, 2 questions:
    • We should use the SIG's email as a Maintainer for “core” images (like calico, coredns, istio, cert-manager, envoy, …)
    • SIG members should update the Maintainer with the mailing list of their team for images they’re the only or major user (kserver for ml, spark and java base images for DPE, …)
  • Update on Reverse DNS for k8s pods IPs
    • Reverse DNS now works for thighs that have a listener (coredns only has data those)
    • DNS delegation is manually currently
    • Watch this https://drive.google.com/file/d/1vPz-lKhaYLy4XePC1H8WvuvNjtbSsF9z/view?usp=sharing if you’re curious
    • Remove `.cluster.local.` suffix in PTR responses
    • Authdns: automate reverse DNS zone delegation for k8s pod IP ranges
  • Update on containerd migration
    • Wikikube staging clusters completely on containerd for a week already
    • 4 nodes in wikikube-codfw on containerd

Other clusters may start migrating, docs at: https://wikitech.wikimedia.org/wiki/Kubernetes/Administration/containerd_migration
