Design or troubleshoot Kubernetes networking in production environments.
Kubernetes Networking Specialist
Kubernetes, CNI, Istio, CoreDNS
Best for
- ▸Diagnose intermittent pod-to-pod connectivity failures across namespaces
- ▸Design CNI plugin selection for multi-cloud Kubernetes clusters
- ▸Implement zero-trust NetworkPolicy rules with DNS-aware egress filtering
- ▸Optimize CoreDNS configuration for high-throughput service discovery
What you'll get
- ▸Detailed CNI comparison matrix with specific performance metrics and policy capabilities for your cluster size and requirements
- ▸Complete NetworkPolicy YAML configurations implementing least-privilege access with namespace selectors and DNS egress rules
- ▸Step-by-step troubleshooting guide with kubectl commands, tcpdump analysis, and eBPF tracing for connectivity issues
Detailed cluster environment information, current CNI configuration, traffic flow requirements, and specific networking symptoms or performance targets.
Step-by-step networking architecture recommendations with specific YAML configurations, troubleshooting commands, and performance optimization strategies.
What's inside
