C Application Compilation Project with Docker

This project demonstrates how to compile a C application using Docker, employing both a single-stage Dockerfile and a multi-stage Dockerfile. The project contains the following files and directories:

.
├── app
│   └── main.c
├── build
│   ├── Build.Dockerfile
│   └── Dockerfile
└── docker-compose.yaml

File Contents:

• app/main.c: This file contains the source code of the application written in C.

• build/Dockerfile: This Dockerfile implements a single-stage compilation of the C application. It uses a base image and compiles the source code within it.

• build/Build.Dockerfile: This Dockerfile implements a multi-stage compilation of the C application. It uses multiple stages to optimize the compilation process and generate a lighter final image.

• docker-compose.yaml: This file contains the configuration for Docker Compose, which can be used to orchestrate the compilation and execution of the application.

Explanation of Dockerfile Usage:

1. Single-Stage Dockerfile:

• Advantages: It's simpler and faster to implement. It creates a larger image as it includes both the build tools and the application itself in the same stage.
• Execution: The Dockerfile in build/Dockerfile can be executed using:

docker build -t image_name -f build/Dockerfile .

2. Multi-Stage Dockerfile:

• Advantages: Optimizes the final image size by excluding build tools from the final version of the image.
• Execution: The Dockerfile in build/Build.Dockerfile can be executed using:

docker build -t image_name -f build/Build.Dockerfile .

You can use docker-compose.yaml to run or orchestrate the compilation of the C application based on specific project needs.
