Kubernetes Patterns

Purpose - comprehensive description

This skill covers the most advanced edge cases of Kubernetes operational patterns. It implements deep eBPF tracing scenarios, complex high-cardinality PromQL alerts, and sophisticated Sidecar container implementations for service meshes and telemetry.

Core Principles

1. Decouple observability from application logic using highly constrained Sidecars.
2. Leverage eBPF for zero-instrumentation, kernel-level networking and tracing.
3. Implement deterministic PromQL alerts with pre-calculated recording rules.
4. Enforce strict resource limits (requests=limits) on all sidecar containers.
5. Prioritize fail-closed for security mechanisms and fail-open for telemetry.
