Kubernetes Networking Deep Dive
Kubernetes Networking
Course Introduction
Welcome to the Kubernetes Networking course! I’m Weston Bassler, your instructor for this hands-on journey into container networking. Unlike traditional tutorials, this course features instant, browser-based labs so you can apply new concepts the moment you learn them.
Note
All labs spin up directly in your browser—no local installation needed. Just log in and start practicing!
Browser-Based Hands-On Labs
We believe in learning by doing. After each lesson, you’ll work through real-world scenarios that reinforce key concepts and tools.
What You’ll Learn
By the end of this course, you’ll have a thorough understanding of Kubernetes networking—from basic pod connectivity to advanced security policies and multi-cluster topologies.
| Module | Topics Covered |
|---|---|
| 1. Kubernetes Networking Architecture | Host-only vs. Pod-to-Pod communication, Overlay networks, CoreDNS, Network Policies |
| 2. Container Network Interfaces (CNIs) | Installing and configuring Calico, Flannel, Weave; deep dive into Cilium features and eBPF |
| 3. Kubernetes Services | ClusterIP, NodePort, LoadBalancer, ExternalName; Endpoints & EndpointSlices; DNS-based service discovery |
| 4. Ingress Controllers & Resources | Deploying Traefik Ingress; ExternalDNS integration; Intro to Service Mesh and multi-cluster routing |
| 5. Network Security | mTLS encryption & authentication; cert-manager with Let’s Encrypt; Cilium Network Policies; Hubble CLI troubleshooting |
Why This Course Stands Out
- Instant browser labs—no VM setup or cluster installation required.
- Real-world challenges—solve common networking issues yourself.
- Deep dives into Cilium and eBPF—stay ahead with cutting-edge CNI technology.
- Community support—join the discussion on the KodeKloud Forum.
