NestJS Deployment
Docker builds, Memory tuning, and Graceful shutdown.
Best use case
NestJS Deployment is best used when you need a repeatable AI agent workflow instead of a one-off prompt.
Docker builds, Memory tuning, and Graceful shutdown.
Teams using NestJS Deployment should expect a more consistent output, faster repeated execution, less prompt rewriting.
When to use this skill
- You want a reusable workflow that can be run more than once with consistent structure.
When not to use this skill
- You only need a quick one-off answer and do not need a reusable workflow.
- You cannot install or maintain the underlying files, dependencies, or repository context.

# Deployment & Ops Standards
## **Priority: P1 (OPERATIONAL)**
Docker optimization and production deployment standards for NestJS applications.
## Docker Optimization
- **Multi-Stage Builds**: Mandatory.
1. **Build Stage**: Install `devDependencies`, build NestJS (`nest build`).
2. **Run Stage**: Copy only `dist` and `node_modules` (pruned), use `node:alpine`.
- **Security**: Do not run as `root`.
- **Dockerfile**: `USER node`.
## Runtime Tuning (Node.js)
- **Memory Config**: Container memory != Node memory.
- **Rule**: Explicitly set Max Old Space.
- **Command**: `node --max-old-space-size=XXX dist/main`
- **Calculation**: Set to ~75-80% of Kubernetes Limit. (Limit: 1GB -> OldSpace: 800MB).
- **Graceful Shutdown**:
- **Signal**: Listen to `SIGTERM`.
- **NestJS**: `app.enableShutdownHooks()` is mandatory.
- **Sleep**: Add a "Pre-Stop" sleep in K8s (5-10s) to allow Load Balancer to drain connections before Node process stops accepting traffic.
## Init Patterns
- **Database Migrations**:
- **Anti-Pattern**: Running migration in `main.ts` on startup.
- **Pro Pattern**: Use an **Init Container** in Kubernetes that runs `npm run typeorm:migration:run` before the app container starts.
## Environment Variables & CI/CD
- **CI/CD Pipelines (GitHub, GitLab, Azure, etc.)**:
- If you modify `src/config/env.validation.ts` to add a new environment variable, you **MUST** map it explicitly in your deployment pipeline/infrastructure-as-code.
- **Platform Context**:
- **Cloud Run/ECS**: Variables must be explicitly passed in the service definition.
- **Kubernetes**: New variables must be added to the `Deployment` manifest or `ConfigMap`/`Secret`.
- **Lambda/Serverless**: Must be added to `serverless.yml` or provider console.
- **Fundamental Rule**: Application code configuration changes are "breaking changes" for the infrastructure layer. Never assume environment inheritance.Related Skills
