description	Principal/Senior-level NGINX Ingress playbook for traffic management, edge reliability, multi-tenant ingress governance, security controls, performance tuning, and production Kubernetes ingress operations. Use when: designing ingress topology, debugging traffic routing, tuning edge behavior, securing external access, or operating shared ingress platforms.

NGINX Ingress Mastery (Senior → Principal)

Operate

• Start from request flow, trust boundaries, tenant separation, and failure blast radius.
• Treat ingress as product-facing critical infrastructure.
• Prefer explicit routing, sane defaults, and clear ownership of TLS, auth, and rewrite behavior.
• Optimize for safe change rollout, debuggability, and predictable traffic behavior.

Default Standards

• Routing rules should be understandable by humans.
• Edge timeouts, retries, body limits, and buffering should match workload reality.
• Multi-tenant ingress needs policy before scale.
• Observability at the edge is mandatory.
• Controller upgrades and config changes should be reversible.
