Simple Java Docker Practice Project

This repository is part of my Docker learning journey. In this project, I practiced containerizing a simple Java application using Docker.

The goal of this project was to understand:

• How Docker works with Java applications
• How to write a Dockerfile
• How to build and run Docker images and containers

• Clone an existing Java application repository
• Write a Dockerfile for the Java application
• Build a Docker image
• Run the application inside a Docker container
• Understand the complete Docker workflow as a beginner

• Java
• Docker
• Git
• Linux (Ubuntu)

The Dockerfile is used to containerize the Java application.

1. Use a Java-based image
2. Copy application files into the container
3. Compile the Java program
4. Run the Java application inside the container

This helped me understand how Java applications run inside Docker containers.

git clone < repo-URL >
cd <project>

docker build -t simple-java-app .

docker run simple-java-app

After running the container, the Java application executes successfully inside Docker, confirming that the containerization was done correctly.

Through this project, I learned:

• How to write a basic Dockerfile
• How Docker images and containers work
• How to containerize a Java application
• Docker commands like build, run, and ps
• Practical hands-on experience with Docker

As a DevOps learner, this project helped me build strong fundamentals of Docker before moving to advanced topics like:

• Docker Compose
• Kubernetes
• CI/CD Pipelines
• Cloud Deployments (AWS / EKS)
