This project demonstrates a simple Java application built and deployed using modern DevOps tools and practices, including Jenkins, Ansible, AWS, Git, and Docker Hub.
The project is a basic Java "Hello World" application.
The main goal is to automate the building, testing, containerizing, and deployment of the app using CI/CD pipelines.
- Git: Source code version control, hosting the code on GitHub.
- Jenkins: CI/CD automation server to build, test, and deploy the app automatically on each code change.
- Maven: Java build tool used to compile and package the application.
- Docker: Containerizing the Java application for consistent deployment.
- Docker Hub: Hosting Docker images to be pulled during deployment.
- Ansible: Automating deployment steps on remote servers (e.g., AWS EC2 instances).
- AWS EC2: Hosting the deployed application on cloud virtual machines.
-
Code is pushed to GitHub repository.
-
Jenkins Pipeline is triggered automatically:
- Jenkins clones the GitHub repo.
- Runs Maven commands to build and test the Java app (
mvn clean packageandmvn test). - Builds a Docker image containing the Java app.
- Pushes the Docker image to Docker Hub.
-
Ansible Playbook runs from Jenkins:
- Connects to AWS EC2 instances.
- Pulls the latest Docker image from Docker Hub.
- Stops any running containers of the app.
- Starts new containers with the updated app.
- AWS account and EC2 instance(s) running Linux
- Jenkins installed and configured with Git, Maven, Docker, and Ansible plugins
- Docker Hub account with credentials saved in Jenkins
- SSH access configured for Ansible to manage EC2 servers
- Push your Java code changes to GitHub.
- Jenkins pipeline automatically builds, tests, and pushes Docker images.
- Ansible deploys the updated Docker container to the AWS EC2 server.
