Configuring Kube Proxy

kube-proxy is an agent service that runs on each node in the cluster to create, update, and delete network rules on the nodes, usually through the use of Linux iptables. These network rules allow inter-pod and intra-pod communication inside and outside the Kubernetes cluster.

Irrespective of whether you use a self-managed Kubernetes cluster or a hosted one, you need to control the configuration options that you pass to kube-proxy. As we are using EKS, kube-proxy comes pre-deployed with the cluster, which leaves us without a full control over its configuration, and we need to change this.

During the cluster's lifetime, you need to control the periodic updates of kube-proxy and include them within the cluster's updates' pipeline. Also, you need to optimize its performance by controlling the runtime parameters, including --iptables-sync-period, --iptables-min-sync-period, and --proxy-mode.
