Walkthrough

Documentation update to the NodeLocal DNSCache configuration guide clarifying that node-rebuild cluster upgrades discard kubelet configuration. Users are instructed to persist NodeLocal DNS settings by adding the --cluster-dns parameter to kubeletExtraArgs in three specified cluster-template locations.

NodeLocal DNS upgrade persistence guidance

Summary

NodeLocal DNS kubeletExtraArgs persistence guidance docs/en/networking/functions/configure_node_local_dns.mdx

Updated the "Important Notes" section to generalize the upgrade warning from "Alauda OS Cluster Upgrade" to "Cluster Upgrade via Rebuilding" and added guidance explaining that rebuilding-based upgrades discard kubelet configuration changes. Users are instructed to persist NodeLocal DNS configuration by adding --cluster-dns to kubeletExtraArgs in three template locations: KubeadmControlPlane init/join and KubeadmConfigTemplate join sections.

• alauda/acp-docs#836: Mirrors the same configure_node_local_dns.mdx update, generalizing the kubelet-delta/upgrade warning to "Cluster Upgrade via Rebuilding" and instructing persistence of NodeLocal DNS via kubeletExtraArgs --cluster-dns in three template locations.

Poem

🐰 A DNS path through nodes so fine,
When clusters rebuild and realign,
Add --cluster-dns to persist and keep,
Your NodeLocal magic, configured deep!
