This course simplifies the complexities of Kubernetes networking, offering in-depth insights and hands-on experience with modern container networking. Immerse yourself in multiple hands-on labs designed to simulate real-world scenarios, putting you in the shoes of a recently hired SRE at Company X.
Section 1 - Networking Overview
Start with an introduction to Kubernetes networking, exploring its architecture and crucial role in container orchestration. Dive into Kubernetes Networking Models, comparing Host-Only, Overlay, and Network Policies, coupled with best practices to ensure robust and secure networking.
Section 2 - CNIs
Grasp the fundamentals of Container Networking Interfaces (CNI) like Calico, Flannel, and Weave, and learn to configure and manage Cilium as the selected CNI for this course. Enhance your understanding of network add-ons such as CoreDNS and kube-proxy. Master pod networking, intra-pod communication, and IP addressing along with network namespaces and policies to control and secure pod communications.
Section 3 - Services
Understand the intricacies of Kubernetes Services, including Cluster IP, NodePort, LoadBalancer, and ExternalName Services. Learn about Endpoints and Endpoint Slices, their creation, and practical examples. Explore DNS-based service discovery mechanisms that enable seamless service communication within the cluster. Finally, delve into common networking issues and their resolution, along with troubleshooting tools and techniques.
