Kubernetes IPVS forwarding mode is widely used for high-performance load balancing, but misconfigured readiness probes can lead to uneven traffic distribution across cluster nodes. This article delves into the interaction between readiness probes and IPVS, offering strategies to optimize packet forwarding paths. Key techniques include adjusting probe thresholds, aligning service endpoints with node topology, and leveraging external traffic policies for cross-cluster scenarios. These optimizations can significantly reduce latency and improve resource utilization in production environments. For SREs and platform engineers, understanding these nuances is critical for maintaining efficient, scalable Kubernetes networking.
