Cgroups V2: Before You Jump In

Adobe jumped into upgrading to cgroups v2 head-first and hit rocks beneath the surface. Our telemetry broke, HPA ceased to function, and then we started to notice some issues with our java apps. We ended up having to drag ourselves back to shore. However, that doesn’t mean you shouldn’t take the plunge! In this talk, we will give a background on what cgroups are (and why you should care) and how this impacts cloud-native architecture. We’ll also be touching on new cgroupv2 features in development for Kubernetes, such as tools to better manage resource utilization and an intelligent OOM killer for multi-container pods. At last spring’s KubeCon + CloudNativeCon Europe, SIG-Node shared their roadmap for Cgroups and Kubernetes, letting the community know where support for v1 and v2 is heading. This talk will help guide you in your transition and provide valuable feedback as you make the jump. Learn from our bumps and bruises, the water’s great!
