Why this matters
- This topic directly affects how reliably BookStore reaches production — compose runs bookstore api with postgres and redis locally with one command and health-aware startup order..
- Interviewers connect hands-on commands and manifests to real delivery stories, not buzzwords.
- Later modules assume you can explain both the why and the concrete file or command involved.
- Platform maturity shows up when teams automate this instead of relying on tribal knowledge.
Multi-service stack
API + Postgres + Redis: BookStore engineers treat this as part of the standard path from laptop to docker compose local dev readiness. Document decisions in the team runbook so on-call knows which knobs exist.
Key ideas
- Multi-service stack — primary idea for docker-compose-local-dev
- BookStore context — catalog API, checkout, and inventory services share the same pattern
- Automation — prefer pipeline jobs over manual SSH steps
- Verification — staging must prove the change before prod traffic
Health-aware depends_on
Local parity with staging: When staging matches production architecture, BookStore catches misconfigurations early. Pair this section's practice with observability dashboards to confirm behavior under load.
Key ideas
- Health-aware depends_on — operational detail
- Rollback — know how to revert without rebuilding artefacts
- Security — least privilege for deploy roles
- Documentation — link runbooks from the service README
Production checklist
Before promoting BookStore changes tied to this topic, run automated tests, inspect artefact immutability (image digest or JAR checksum), execute a staging smoke test on /actuator/health, and watch error-rate dashboards for thirty minutes after prod rollout.
Key ideas
- Staging soak — validate under synthetic load
- Change ticket — attach pipeline URL and artefact digest
- On-call — page owner stays on dashboards during rollout
- Post-deploy — record metrics baseline for comparison

Quick recall
Everything you need if you only revisit this box.
- BookStore uses docker compose local dev as a standard delivery practice.
- Prefer automation and versioned config over manual server changes.
- Staging proves changes before customer-facing promotion.
- Observability confirms success — do not rely on silence alone.
- Rollback plans must be tested, not invented during an outage.
- Security and least privilege apply to every pipeline and cluster role.
