What's new in Kubernetes 1.13?

Kubernetes 1.13, released on December 3, 2018, introduces several new features and updates targeted at improving configuration management, core components, hardware support, storage, and cloud integration. Notable enhancements include the dynamic audit configuration, which allows audit events to be forwarded to remote APIs, and the support for webhook conversion for custom resources, enabling different schemas for different CRD versions. The API-server dry-run feature moves to beta, allowing users to simulate API requests without modifying the state, and the kubectl diff command provides a preview of changes before they are applied. Kubernetes cluster creation is simplified through improvements in kubeadm, while taint-based evictions and scheduler performance enhancements further optimize cluster operations. Additionally, Kubernetes 1.13 enhances hardware support with monitoring plugins for third-party devices and expands storage capabilities by making raw block devices available via persistent volumes and stabilizing the Container Storage Interface for third-party volume plugins. Cloud integration is strengthened with features like the AWS ALB ingress controller and the debut of the AWS cloud-controller-manager, along with upgrades to Azure availability zones and cross-resource group node support. This version also marks the deprecation of support for etcd2, reflecting ongoing efforts to streamline and modernize the platform.
