Installation

Prerequisite:

Step 1: Build the application with the docker

Change directory to the root directory of the node.js application

  cd /path-to-node.js-app/

Build and tag the application

  docker build -t bongu1302/demo:v2 .

Check whether the application is built or not:

  docker images

Step 2: Run the application

  docker run -d -p 8080:8080 bongu1302/demo:v1

Notes that -d is run docker in background, flag -p stands for port

Check container is running or not, When the app is built, it is called an image, when we run the image, it is called the container

  docker ps

  docker push bongu1302/demo:v1
