Cilium Fundamentals for Kubernetes Networking

Navigating Kubernetes networking can be complex, often becoming a bottleneck for deploying robust and secure applications. This course introduces you to Cilium, a powerful Container Network Interface (CNI) that leverages eBPF to revolutionize how you manage network connectivity, security, and observability in your clusters. By completing this course, you will gain the practical knowledge to confidently deploy, configure, and manage Cilium in your Kubernetes environments. You'll be equipped to secure your applications with advanced network policies, troubleshoot network issues with deep visibility, and prepare your infrastructure for scalable, multi-cluster deployments. What you'll learn: * Understand the foundational role of eBPF in modern networking and Cilium's architecture. * Deploy and configure Cilium as the Container Network Interface (CNI) for Kubernetes clusters. * Implement granular network policies to secure application communication within and across namespaces. * Leverage Hubble for real-time network observability, traffic visualization, and troubleshooting. * Explore advanced Cilium features like transparent encryption and DNS-aware policies. * Apply GitOps principles for managing Cilium network policies declaratively. * Configure multi-cluster connectivity and shared services using Cilium. This course begins with core networking concepts and foundational eBPF principles before guiding you through practical Cilium installation, configuration, and advanced feature implementation. You will progress from basic network policies to comprehensive observability and multi-cluster strategies. This course is for beginners in cloud-native technologies, developers, and operations professionals who want to master Kubernetes networking with Cilium. No prior experience with Cilium or eBPF is required. Start building a more secure and observable Kubernetes network today.
