This post focuses on installing Cilium as the CNI in a K3s cluster. While K3s includes its own default networking stack, Cilium provides an alternative that leverages eBPF for networking, security, and observability. This setup can be useful for scenarios requiring more granular network policies, improved performance, or deeper insights into cluster traffic.</p> <p>This guide specifically targets installing Cilium in kube-proxy replacement mode, which eliminates the need for the standard kube-proxy component and allows Cilium to handle all service routing more efficiently using eBPF.</p> https://apurv.me/posts/kubernetes-routing-external-traffic-to-local-cluster/ Fri, 28 Feb 2025 01:55:15 +0530 https://apurv.me/posts/kubernetes-routing-external-traffic-to-local-cluster/ <hr> <p>This post is part of our ongoing DevOps series focused on Kubernetes and GitOps practices. So far, we&rsquo;ve explored various aspects of DevOps with FluxCD, and our upcoming posts will cover application deployment strategies in Kubernetes.</p> <p>A significant challenge when working with a local Kubernetes environment (like our K3s setup) is the lack of public network access, which is automatically handled in managed Kubernetes offerings from cloud providers. For locally hosted clusters, establishing secure public connectivity is essential for many real-world scenarios.</p>
