Kubernetes 1.23 – What's new?

Kubernetes 1.23 introduces a range of enhancements, with 11 features reaching stable status, 15 existing features improved, and 19 new additions. Highlighted features include the kubectl events command, OpenAPI v3 support, and gRPC probes, while significant projects like CSI Drivers and Windows support continue to evolve. Major features graduating to General Availability (GA) include CronJobs, IPv4/IPv6 dual-stack support, ephemeral volumes, and the Horizontal Pod Autoscaler (HPA) API. This release also involves several deprecations and removals, alongside updates in API validation, improvements in job scheduling, and advancements in storage support, particularly with the migration of Container Storage Interface (CSI) drivers. The Kubernetes team shows a clear vision with ongoing modularity efforts, particularly in delegating features to CSI drivers and simplifying logging and configuration processes. Users are encouraged to be aware of deprecations and to consider upgrading their clusters to leverage these new capabilities fully.
