Overview

Welcome to the Java Docker Project. In this series of tutorials, we will build a complete CI/CD pipeline for a Java application, starting from the basics and progressively adding advanced features.

Project Goal

The goal of this project is to take a simple "Hello World" Java application and automate its entire lifecycle: 1. Build: Compile the code using Maven. 2. Containerize: Package the application as a Docker container. 3. Manage Artifacts: Store and version Docker images in JFrog Artifactory. 4. Deploy: Deploy the application to Dev, QA, and Prod environments. 5. Secure: Scan the code (SonarQube) and the container (Anchore) for vulnerabilities. 6. Orchestrate: Deploy the application to a Kubernetes cluster. 7. Optimize: Use Jenkins Shared Libraries to keep code DRY.

Prerequisites

Before starting, ensure you have: - A Jenkins instance running. - Docker installed and configured on your Jenkins agent. - Access to a JFrog Artifactory instance. - Access to a SonarQube server. - Access to a Kubernetes cluster (for later stages). - Basic knowledge of Git, Java, and Jenkins pipelines.

Project Stages

1. Build & Push to JFrog
2. Deploy to Environments
3. Trigger Downstream Jobs
4. Deploy from Multiple Repos
5. Using JFrog CLI
6. Artifact Promotion
7. SonarQube Integration
8. Anchore Security Scanning
9. Deploy to Kubernetes
10. Shared Libraries
