How can I scale a Node.js application using Docker?

You can scale a Node.js application in Docker by using Docker Compose or Kubernetes to manage multiple containers.

What are the benefits of using Docker for scaling?

Docker allows for easy deployment, isolation of services, and efficient resource management, making scaling simpler.

Can you give me an example of a Docker Compose file for scaling?

Sure! Here's a simple example:

version: '3'
services:
  app:
    image: my-node-app
    deploy:
      replicas: 3
    ports:
      - '3000:3000'

What should I consider when scaling my application?

Consider load balancing, database connections, and resource limits to ensure optimal performance.
