CI CD Pipeline Engineering

CI/CD Pipeline Engineering

Build pipelines that prove system behavior end-to-end, not just compile success.

Decision Criteria

• Every pipeline stage must map to a concrete failure class: correctness, security, compatibility, performance, release safety.
• Release gates are based on measurable checks (tests, coverage targets, infra verification, migration checks), not manual confidence.
• Pipeline changes must preserve reproducibility across local, CI, and release environments.
• Rollback path must be validated before rollout automation is approved.

Principal Practices

• Run backend unit/integration suite (go test ./... -v -race -cover) and containerized verification (make verify) in CI.
• Include schema migration forward/backward checks and seed safety checks for critical environments.
• Add contract checks for API envelope and key endpoint behaviors used by iOS.
• Require artifact traceability: commit SHA, migration version, and environment promotion metadata.

Failure Modes & Anti-Patterns

• Green pipelines that skip integration dependencies (PostgreSQL/Redis/LocalStack).
• Long-running flaky checks with no quarantine and no reliability owner.
• Deploying build artifacts that were not validated against migration state.
• Manual production deploy steps without auditable approval trail.

Project-Specific Examples

• Pipeline should validate make test plus at least one containerized end-to-end flow matching verifier expectations.
• Release candidate should prove queue-driven worker path and leaderboard fallback behavior before tag promotion.
