As Kubernetes and container technologies evolve, shifting from cgroup v1 to cgroup v2 has become a pivotal development. With cgroup v2 available in Kubernetes since v1.25, we're at a crossroads where many users and organizations must decide when and how to transition fully to this new system. Despite the benefits of cgroup v2, including better resource management and enhanced capabilities, users frequently encounter unexpected challenges signaling a gap in readiness and understanding.
This talk will address the practical implications of moving to cgroup v2, discuss the coordinated efforts to deprecate cgroup v1, and propose actionable strategies to bridge the gap between the Kubernetes community, system administrators, and developers. By focusing on real-world experiences and providing clear guidance, this session aims to equip you with the knowledge and tools to navigate this significant change confidently.
