Add Docker build verification and health-check timeout tuning to CI

[Jagadeeshftw]

Description

The CI pipeline does not build or test the Docker image, meaning a broken Dockerfile or misconfigured HEALTHCHECK directive can reach production undetected. Additionally, /health/ready and /health/live timeouts in src/config/health.ts (HealthCheckManager) are hardcoded rather than configurable. A Docker build-and-smoke-test CI step and environment-driven health-check timeouts must be added.

Requirements and context

• Add a docker-build job to .github/workflows/ci.yml that runs docker build, starts the container, and polls GET /health/live until healthy or times out
• Parameterise the HEALTHCHECK --timeout and --interval in Dockerfile via ARG build arguments defaulting to sensible values
• Add HEALTH_CHECK_TIMEOUT_MS and HEALTH_CHECK_INTERVAL_MS to src/config/env.ts and wire them into HealthCheckManager
• Must be secure, tested, and documented
• Should be efficient and easy to review

Suggested execution

Fork the repo and create a branch

git checkout -b feature/ci-docker-build-healthcheck

Implement changes

• Update/Write: .github/workflows/ci.yml — add docker-build job with smoke test
• Update/Write: Dockerfile — parameterise HEALTHCHECK timeout/interval via ARG
• Update/Write: src/config/env.ts — add health-check timeout env vars
• Update/Write: src/config/health.ts — read timeout from env in HealthCheckManager
• Write comprehensive tests: tests/config/health.test.ts
• Add documentation: docs/deployment.md — document Docker health-check tuning
• Include clear code comments and types
• Validate security assumptions

Test and commit

• Run tests: pnpm test (or pnpm test:coverage)
• Cover edge cases: container starts healthy, container starts unhealthy (smoke test fails CI), custom timeout env var respected, zero timeout rejected
• Include test output and security notes
