KOPS DROPS IN-TREE CLOUD CONFIG, AZURE SHIFTS TO SECRETS

kOps is gutting years of cloud configuration cruft, moving Azure cloud-config from per-node files to a cluster-managed Secret while deprecating the unused in-tree cloud provider flag that's been dead code since Kubernetes 1.31.

The kOps team completed a three-PR cleanout of the in-tree cloud-provider path [1][2][3]. Since kOps enforces --cloud-provider=external across all clouds and versions 1.31+, the entire --cloud-config flag and the azure.json file it pointed to have been no-ops. Meanwhile, the Azure cloud-controller-manager now reads configuration from a Kubernetes Secret instead [4], matching upstream Helm chart conventions and giving operators a single cluster-managed object rather than managing per-node files through nodeup. The related Azure nodeup config fields are being trimmed [5], reducing surface area. In parallel, the Cluster Autoscaler is making smarter resource decisions: it now respects per-group resource quotas during scale-up balancing [6], fixing a bug where groups could exceed their quota limits. The autoscaler also shipped memory optimizations by stripping managed fields from informer caches [7][8], a win for large clusters, and added observedGeneration to VPA status for standardized condition tracking [9]. The Scheduler fixed pod group preemption behavior to match preemptor eligibility rules [10], and kubeadm now warns users who've configured kube-proxy with the deprecated IPVS mode [11], pushing them toward nftables (GA since 1.33) or legacy iptables on older kernels.
