Run Node.js server in Docker container

• Build your image

docker build -t server .

• Run your container on port 4000:4000 (local port : container port)

docker run  -p 4000:4000 node-server

• Alternatively, run your container with -v flag so you don't have to rebuild image to apply code changes. Very convenient when developing.

docker run  -p 4000:4000 -v /Path/to/your/local/file:/app node-server

• In your local machine, open your web browser and visit localhost:4000. To see response.
