Dockerlite System Documentation

This documentation explains how to use our custom Docker-like system with the base64 encoding/decoding service.

System Requirements

• Linux operating system
• Root privileges
• Basic tools: curl, bash, unshare, chroot

Directory Structure

.
├── dockerlite.sh          # Main container management script
├── app/
│   ├── Dockerfile          # Container definition for the base64 service
│   ├── package.json        # Node.js dependencies
│   └── server.js           # Express server implementation
└── containers/

Installation

• Clone or create the project structure:

git clone https://github.com/yashmakhija/docklite

• Navigate to the project directory:

cd docker-lite

Basic Commands

• List all available commands:

./docker-lite.sh

• Build an image:

sudo ./docker-lite.sh build app/Dockerfile

This will output an image ID - save it for the next step.

• List all images:

sudo ./docker-lite.sh images

• Run a container:

sudo ./docker-lite.sh run <image-id>

• List all containers:

sudo ./docker-lite.sh ps

• Remove a container:

sudo ./docker-lite.sh rm <container-id>

• Remove an image:

sudo ./docker-lite.sh rmi <image-id>

Limitations

Current implementation has the following limitations:

• Basic network isolation
• No volume mounting
• Limited Dockerfile instruction support
• Basic environment variable handling
• No port mapping (uses host network)
• Limited container lifecycle management

Example Workflow

Build the base64 service:

sudo ./docker-lite.sh build app/Dockerfile

Run the container:

sudo ./docker-lite.sh run <image-id>

Test the service:

curl -X POST -d '{"text": "Hello, World!"}' http://localhost:3000/encode

Clean up:

sudo ./docker-lite.sh rm <container-id>
sudo ./docker-lite.sh rmi <image-id>
