Docker ​

Dockerfile ​

dockerfile
FROM node:22-alpine
WORKDIR /app
COPY package*.json ./
RUN npm ci --omit=dev
COPY dist ./dist
USER node
CMD ["node", "dist/index.js"]

docker-compose ​

yaml
services:
  app:
    build: .
    stop_grace_period: 45s

Docker sends SIGTERM on docker stop. lastcall handles it automatically.

Best practices ​

  1. Use STOPSIGNAL SIGTERM (Docker default)
  2. Set stop_grace_period > your shutdownTimeoutMs
  3. Register withHttpServer() for any HTTP service
  4. Use critical: true on database handlers

Health checks ​

During pre phase, mark your health endpoint unhealthy so the load balancer stops routing traffic before drain begins.
