DDD DevOps Integration

DevOps for DDD projects — ArchUnit quality gates (P0 block / P1 warn / P2 report) in CI/CD, multi-module incremental builds, architecture-type-aware Dockerfiles, event-driven DB migration, domain event health monitoring.

Workflow

Step 1: Code & Build — Compile all modules. Domain must compile last (zero framework contamination).

Step 2: Unit Test — Per-module unit tests run independently.

Step 3: ArchUnit Validate — P0 (zero deps, layer compliance) blocks CI; P1 (cycle-free) warns; P2 (naming) reports.

Step 4: Integration Test — Cross-module interaction tests with event store and outbox.

Step 5: Containerize — Build Docker images (monolith fat JAR or split CQRS with tuned JVM args).

Step 6: Deploy — K8s deploy with per-BC namespace, DB migration init containers, health probes.

Step 7: Monitor — Domain metrics (event rate, outbox depth, aggregate load) → Prometheus alerts.

Quality gates run at build time, never against production. Violations block merge, not deployment.
