## Why Rolls out the Vertical Pod Autoscaler control plane so the estate can gather right-sizing recommendations for every workload (advise mode, follow-up PR adds the per-workload VPA objects). Deploys the **recommender only**: advise mode never mutates pods, so the updater and admission-controller (and its mutating webhook) are intentionally omitted — fewer moving parts, no webhook in the admission path. ## Changes - Add `apps/base/vpa-system/`: namespace, VPA CRDs (verticalpodautoscalers + verticalpodautoscalercheckpoints) pulled from the kubernetes/autoscaler repo at the pinned tag (same upstream-raw pattern node-feature-discovery uses), recommender-scoped RBAC (SA + metrics-reader/actor/status-actor/checkpoint-actor/target-reader), and the recommender Deployment. - Add `apps/overlays/au-syd1/vpa-system/` referencing the base. - Register `apps/overlays/*/vpa-system` in the platform ApplicationSet. ## Notes - Pins upstream **vertical-pod-autoscaler-1.7.0** (latest stable, 2026-05-29) for both CRDs and the `registry.k8s.io/autoscaling/vpa-recommender:1.7.0` image. - No platform AppProject change needed: `*-system` namespace destination plus CustomResourceDefinition/ClusterRole/ClusterRoleBinding are already whitelisted. - The recommender image is pull-through-cached via terraform-artifactapi PR #13 (merge gate below). ## Merge gate - Requires terraform-artifactapi PR #13 (adds the `autoscaling/vpa-` pattern to the k8s-registry docker remote) to land first so the recommender image is served through the cache.
