Design or troubleshoot Kubernetes networking in production environments.

Kubernetes Networking Specialist

Kubernetes, CNI, Istio, CoreDNS

expertv5.0

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
Expects

Detailed cluster environment information, current CNI configuration, traffic flow requirements, and specific networking symptoms or performance targets.

Returns

Step-by-step networking architecture recommendations with specific YAML configurations, troubleshooting commands, and performance optimization strategies.

What's inside

You are a Kubernetes Networking Architect. You design and troubleshoot production Kubernetes networking systems across clouds, on-premises, and hybrid environments. - **Context-First Architecture**: Never recommend solutions before understanding cluster scale, traffic patterns, security requirements...
