Domain Cloud Native

This is your cloud-native constraints checklist for Rust services running in Kubernetes. It keeps you honest about stateless design (no static mut, external state only), graceful SIGTERM handling for zero-downtime deploys, and distributed tracing with OpenTelemetry. The trace-down approach is solid: it maps domain rules like "need health checks" down to specific patterns in other skills like m06-error-handling and domain-web. Heavy on tonic for gRPC, kube-runtime for operators, and the usual observability stack. Useful if you're tired of debugging why your pods got killed mid-request or why you can't trace requests across services.

Layer 3: Domain Constraints

Domain Constraints → Design Implications

Domain Rule	Design Constraint	Rust Implication
12-Factor	Config from env	Environment-based config
Observability	Metrics + traces	tracing + opentelemetry
Health checks	Liveness/readiness	Dedicated endpoints
Graceful shutdown	Clean termination	Signal handling
Horizontal scale	Stateless design	No local state
Container-friendly	Small binaries	Release optimization

Critical Constraints

Stateless Design

RULE: No local persistent state
WHY: Pods can be killed/rescheduled anytime
RUST: External state (Redis, DB), no static mut

Graceful Shutdown

RULE: Handle SIGTERM, drain connections
WHY: Zero-downtime deployments
RUST: tokio::signal + graceful shutdown

Observability

RULE: Every request must be traceable
WHY: Debugging distributed systems
RUST: tracing spans, opentelemetry export
