GKE rollout sequencing with custom stages reaches GA
Google Cloud announced the General Availability (GA) release of GKE rollout sequencing with custom stages, a feature that lets platform teams declaratively control the order of Kubernetes cluster upgrades across fleets, environments, and organizations. The RolloutSequence resource defines ordered stages, supports CEL label selectors for granular targeting (e.g., canaries), and provides runtime controls such as pause/resume, force-complete-stage, and cancellation. Operational limits include up to 15 stages per sequence, fleet cluster limits (250 clusters, or up to 2,000 with lightweight memberships and quota increase), per-stage soak durations up to 30 days, and total soak duration up to 90 days. The feature also enforces forced soak when a stage would stall for more than 30 days.
GA technical release from a major cloud provider (Google Cloud) introduces finer-grained, business-aligned control for large-scale Kubernetes lifecycle management, improving operational safety and reliability for organizations that run critical infrastructure (including AdTech platforms).

Key Takeaways & Evidence Grounding
- Google Cloud released GKE rollout sequencing with custom stages as Generally Available (GA).
- The feature introduces a RolloutSequence resource to define ordered upgrade stages across fleets, environments, and organizations.
- Custom stages support CEL label selectors to target subsets of clusters and require a final catch-all stage when selectors are used.
- Operational controls include pause/resume, force-complete-stage, and rollout cancellation; forced soak is triggered if a stage exceeds 30 days.
- Limits: up to 15 stages per rollout sequence; fleets support up to 250 clusters (or up to 2,000 with lightweight memberships and an approved quota increase); total soak duration up to 90 days; per-stage soak up to 30 days.

GKE launches Public Preview of VPA decision logs
Google Cloud's GKE team launched a Public Preview of Vertical Pod Autoscaler (VPA) decision logs that stream structured autoscaler events into Cloud Logging. Available on GKE clusters running version 1.36.0-gke.1601000 or newer, the feature emits persistent, structured JSON control-plane logs (KCP_VPA) from the vpa-controller, capturing recommendation updates, evictions, apply-in-place and apply-on-eviction operations with state, reason, and confidence metadata. Operators can enable KCP_VPA via gcloud CLI and query events in Logs Explorer to troubleshoot autoscaling actions, audit decisions, and enable intent-based autonomous workload management.
