Kubernetes 1.30 reached general availability this week, bringing improvements to pod scheduling and resource management.
The release includes 45 enhancements, with 10 graduating to stable status. Managed Kubernetes services typically adopt new versions within 60-90 days.
Key Changes
Pod scheduling now considers topology spread constraints more efficiently. Clusters with many nodes see improved scheduling latency.
The new PodReadinessGates feature allows external systems to gate pod readiness, useful for service mesh integration.
Resource Management
In-place resource resizing moves to beta. Applications can request more CPU or memory without restarting pods.
This change benefits stateful applications that previously required downtime for vertical scaling.
Security Updates
ServiceAccount token projection improvements enhance security for workload identity. Tokens now include audience restrictions by default.
The Pod Security admission controller adds new warning modes for policy violations.
Upgrade Path
Clusters running 1.28 or 1.29 can upgrade directly. Older versions require sequential upgrades.
Review the deprecation notices before upgrading. Several beta APIs reach end-of-life in this release.
