A simple Node.js application demonstrating containerization with Docker.

This project shows how to dockerize a Node.js application, making it easy to develop, deploy, and run consistently across different environments.

• Docker installed on your machine
• Node.js (for local development without Docker)

1. Clone the repository

   git clone https://github.com/TPVinnie/docker-node-app.git
   cd docker-node-app

2. Build the Docker image

   docker build -t docker-node-app .

3. Run the container

   docker run -p 3000:3000 docker-node-app

4. Access the application Open your browser and navigate to http://localhost:3000

1. Install dependencies

   npm install

2. Start the application

   npm start

docker build -t docker-node-app .

docker run -p 3000:3000 docker-node-app

docker run -d -p 3000:3000 docker-node-app

docker stop <container-id>

docker ps

docker ps -a

To make changes to the application:

1. Edit files in the src/ directory
2. Rebuild the Docker image
3. Run the updated container

For faster development, you can use volume mounting to sync local changes:

docker run -p 3000:3000 -v $(pwd)/src:/app/src docker-node-app

See getting-started-example.md for more detailed instructions.
