Epic 8: Deployment Configuration#96
Conversation
…cutting Epic 6: Cross-Cutting Concerns (DI, Logging, Telemetry, Error Handling)
- Dockerfile: multi-stage build (temurin:21-jdk build, temurin:21-jre-alpine run) with non-root user, health check, and layer caching optimization - .dockerignore: excludes build artifacts, IDE files, docs - docker-compose.yml: app service with SQL Server dependency - azure-pipelines.yml: Build & Test, Docker Build & Push, Deploy to Staging, Health Check, Deploy to Production stages - K8s manifests: Deployment (2 replicas, resource limits, health probes), Service (ClusterIP 80->8080), Ingress (nginx, TLS), ConfigMap, Secret, NetworkPolicy - CUTOVER.md: pre-cutover checklist, data migration steps, canary/DNS cutover procedure, rollback plan, monitoring checklist, success criteria Implements: NM-167, NM-168, NM-169, NM-170
Use actual schema table names (Catalog, CatalogBrand, CatalogType) matching V1__create_schema.sql and JPA entity annotations.
- Multi-stage Dockerfile: build with eclipse-temurin:21-jdk, runtime with eclipse-temurin:21-jre-alpine - Build stage runs mvn package -DskipTests with dependency caching - Runtime stage copies JAR, exposes port 8080, runs as non-root user - Health check configured with curl against /actuator/health - Install curl in alpine runtime for health check support - .dockerignore excludes build output, IDE files, docs, CI/CD configs
- Trigger on push to main and migration/complete-java-migration branches - Build & test job: JDK 21 setup, Maven cache, ./mvnw clean verify, Spotless check - Test results published via dorny/test-reporter - Docker build & push job: builds image and pushes to GHCR - Staging deploy job: SSH into staging VM via appleboy/ssh-action - Health check job: verifies /actuator/health returns UP on staging - Production deploy job: SSH-based deployment with GitHub Environment protection - Required secrets documented: STAGING_VM_HOST, PROD_VM_HOST, VM_USERNAME, VM_SSH_KEY, STAGING_URL, PROD_URL
- DEPLOYMENT.md: full deployment architecture docs (pipeline flow, GitHub Environments/Secrets, Azure VM prerequisites, env var config, DNS guidance) - scripts/setup-vm.sh: idempotent VM setup (Docker install, app dirs, env template) - docker-compose.yml: updated health check to use curl consistently with Dockerfile - .dockerignore already updated in NM-167 to exclude scripts/ and .github/
- Rewrite CUTOVER.md for Azure VM deployment (replaces K8s-focused version) - Rollback plan: steps to revert to .NET application - Cutover checklist: DNS switch, database migration verification, smoke tests - Database rollback strategy: Flyway undo migrations or backup/restore - Traffic switching: single-VM and blue-green (two VMs) approaches - Monitoring checklist: Actuator health, Micrometer/Prometheus metrics - Communication plan: stakeholder notifications before/during/after cutover - Fix: deploy.yml Docker image tag mismatch (use full SHA for GHCR tags)
Addresses Devin Review feedback on PR #91: script was hardcoded to create production.env but is documented to run on both staging and production VMs. Now accepts an argument to generate the correct env file. Updated DEPLOYMENT.md with per-environment usage examples.

Sorry, something went wrong.
- Add docker login to GHCR on remote VMs before docker pull (staging and production deploy jobs) using GITHUB_TOKEN via appleboy/ssh-action envs parameter - Fix DEPLOYMENT.md: docker compose with SQL Server requires SPRING_PROFILES_ACTIVE=prod to override mock profile defaults

🔴 Ingress rewrite-target annotation rewrites all request paths to /, breaking all application routes
The rewrite-target: / annotation in k8s/ingress.yml:10 combined with path: / and pathType: Prefix causes the nginx ingress controller to rewrite ALL incoming request paths to just / before forwarding to the backend. This means requests to /catalog/details/1, /api/brands, /actuator/health, and every other application endpoint will all arrive at the backend as GET /, effectively breaking all routing except the root page.
The application has many routes (/catalog/create, /catalog/edit/{id}, /catalog/delete/{id}, /items/{catalogItemId}/pic, /api/brands, /api/files, /actuator/health, etc. as seen in the controller mappings). None of these would be reachable through the ingress.

This k8s/ingress.yml file is pre-existing — it was added by a prior session's commit (9c28176) that's already in the branch history before Epic 8 work began. Epic 8 replaced the K8s-focused deployment approach with Azure VM SSH-based deployment. The K8s manifests are legacy artifacts from that prior approach and were not modified in this epic.
That said, the observation about rewrite-target: / is correct — if these K8s manifests were ever used, the annotation would break routing. Worth addressing if K8s deployment is revisited in the future.

Summary
Implements all 4 tickets for Epic 8: Deployment Configuration for the eShopLegacyMVC .NET to Java migration. All artifacts are code-only — no actual Azure resources are provisioned or deployed.
