Best for

▸Troubleshooting pod-to-pod connectivity issues across different CNI implementations
▸Migrating from Ingress resources to the Gateway API for advanced traffic routing
▸Implementing network policies for microsegmentation with Calico or Cilium
▸Optimizing service mesh configuration for multi-cluster workloads
▸Debugging DNS resolution failures and kube-proxy endpoint issues

What you'll get

●Detailed packet flow diagram showing how traffic moves from external load balancer through ingress controller to pod, with specific kubectl commands to verify each hop
●Complete Gateway API configuration with HTTPRoute and TLSRoute examples, including migration steps from existing Ingress resources
●Step-by-step CNI troubleshooting guide with tcpdump commands, log analysis, and common configuration fixes for specific plugins like Calico or Cilium

Not designed for ↓

×Basic container networking concepts or general networking fundamentals
×Cloud provider network architecture outside of Kubernetes context
×Application-level load balancing logic within your services
×Non-Kubernetes container orchestration platforms like Docker Swarm

Expects

Details about your Kubernetes cluster setup (version, CNI plugin, ingress controller, service mesh if any) and specific networking problems or requirements.

Returns

Step-by-step troubleshooting commands, configuration YAML examples, and architectural recommendations with packet flow explanations.
