Based on recurring real-world scenarios, we will dive into troubleshooting and mitigations of issues such as IP address allocation delays, registry pull queries per second (QPS), disk throttling. These pose significant impacts on the performance, scalability and stability of Kubernetes clusters. Our discussion will revolve around practical strategies aimed at mitigating such challenges, leveraging multiple block storage volumes, adjusting instance types, tuning registryPullQPS settings, and exploring the benefits of prefix mode for faster IP address allocation. Additionally, we'll examine the role of warm IP pools, and the implications of WARM_ENI_TARGET settings on CNI performance, providing attendees with a comprehensive understanding on how to optimize CNI and Kubelet performance effectively.
