# Docker 101

## Description

This repository documents my understanding of Docker and my attempt to build a Docker image for DGTD (Discontinuous Galerkin Time Domain) code. Docker allows us to package applications and their dependencies into isolated containers, ensuring consistency across different environments.

## Building the Docker Image

To build the Docker image for DGTD code, follow these steps:

### Command Line Interface (CLI)

Use the following CLI commands to build the Docker image:

```bash
docker build -t sample-image .
```

Replace `sample-image` with your preferred image name.

### Platform Compatibility

The Docker image can be built on both UNIX and Windows platforms. Here’s how I set it up:

- **UNIX:** Use Docker Engine.
- **Windows:** Install Docker Desktop.

## Testing the Docker Image

After building the Docker image, test its functionality on both UNIX and Windows environments:

- **UNIX:** Run tests using Docker Engine.
- **Windows:** Run tests using Docker Desktop.

The image should maintain consistency and reproducibility across platforms, demonstrating Docker's versatility in managing application dependencies.

## Usage

This repository serves as a guide for packaging DGTD code and other applications in Docker containers in the future. Adjust Dockerfile configurations and testing procedures as necessary for specific application requirements.
