Cgroupv2 - Coming Soon to Kubernetes Clusters

Explore the upcoming transition to cgroupv2 in Kubernetes clusters through this informative conference talk by David Porter from Google and Mrunal Patel from RedHat. Gain insights into the new kernel APIs for resource management, understand what cluster administrators need to be aware of during the transition, and discover the new features that cgroupv2 will unlock in Kubernetes. Learn about memory throttling, disk latency targets, and pressure monitoring. Delve into active KEPs in Kubernetes that leverage these new capabilities and future developments in this space. Understand how cgroups underlie resource management in Kubernetes, focusing on reserving, allocating, and isolating finite resources on nodes such as CPU, memory, disk, and network. Get clarity on the controversial topic of CPU limits and their potential for unintended throttling. Discover how kubelet utilizes the underlying Linux kernel cgroups for resource isolation and what changes to expect with cgroupv2.
