Docker 101

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.

The documentation is up here.

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:

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.
