KEP of the Week
KEP 4569: Move cgroup v1 support into maintenance mode
This (KEP) aims to move cgroup v1 support in Kubernetes to maintenance mode, aligning with the industry's transition to cgroup v2 as the default for Linux kernel resource management. With cgroup v2 offering better functionality, consistency, and scalability, and major Linux distributions and projects like systemd phasing out cgroup v1, Kubernetes must adapt to maintain compatibility and leverage these improvements. This shift reflects the broader ecosystem's move away from cgroup v1, making it necessary for Kubernetes to follow suit. Removing cgroup v1 support. Deprecation and removal will be addressed in a future KEP.
This KEP is tracked for stable release in v1.31.
