# Dockerized Node.js Hello World
A simple Hello World Node.js CLI application containerized with Docker.
## Installation
1. Clone this repository:
```bash
git clone
cd dockerize-node
```
2. Install dependencies (if any):
```bash
npm install
```
## Development Setup
### Prerequisites
- Node.js 24.9.1 or compatible version
- npm 10.1.0 or higher (comes with Node.js 24.9.1)
- Docker (for container deployment)
### Engine Requirements
```json
"engines": {
"node": ">=24.9.1",
"npm": ">=10.1.0"
}
```
The project uses:
- Base image: `node:24.9.1-alpine` (minimal Node.js image)
- Type: ES Modules (`"type": "module"` in package.json)
### Local Development
To run the application locally without Docker:
```bash
node index.js
```
## Docker Commands
### Build the Docker Image
Node.js environment is set to production by default.
```bash
docker build -t dockerize-node .
```
If you want to set the Node.js environment to development:
```bash
docker build -t --build-arg NODE_ENV=development .
```
### Run the Container
```bash
docker run -it dockerize-node
```
This will run the Hello World script inside the container and output the result.
The `-it` parameter is important, or else the coloring won't work.
### View Previous Container Logs
```bash
docker logs $(docker ps -a -q --filter ancestor=dockerize-node --latest)
```
## Development
1. Make changes to the code
2. Build the Docker image: `docker build -t dockerize-node .`
3. Run the container: `docker run -it dockerize-node`
4. Test your changes
## Notes
Since this is a simple CLI application that runs and exits, there's no need for port mapping or long-running container management. Each `docker run` command will:
1. Create a new container
2. Execute the Hello World script
3. Output the result
4. Exit automatically
