Node Deployment

This lesson is part of Node.js · All levels

Summary

This lesson discusses modern application deployment strategies, from Docker containers, PaaS platforms such as Railway/Render, to Kubernetes orchestrators. You'll understand the concept of image vs container, health check, and blue-green/rolling updates to release without downtime. Good deployment is always accompanied by a quick rollback. (Node.js)

Key points

Use the multi-stage Dockerfile to make the image small and secure.
PaaS (Render, Railway, Fly.io) makes deployment easy without taking care of the server.
Kubernetes is suitable for large scale deployment, autoscaling, and rolling updates.
Provide a HEALTHCHECK or endpoint/healthz for monitoring the health of the service.
Run the process as a non-root user and use .dockerignore.
