Jenkins Distributed Build System on AWS A comprehensive Jenkins remoting setup demonstrating distributed builds across multiple specialized agents on AWS EC2 infrastructure.
🚀 Features
Multi-Agent Distribution: Specialized agents for different build types Security Hardened: SSH key authentication, disabled controller executors. Cross-Platform: Linux (Ubuntu) and Windows agent support Docker Integration: Container building and deployment Pipeline Automation: Complete CI/CD workflow AWS Cloud Ready: EC2 optimized configurations
📋 Prerequisites AWS Resources
AWS Account with EC2 access 4 EC2 instances (1 controller + 3 agents) Security groups configured SSH key pairs for EC2 access
Local Requirements
SSH client AWS CLI (optional) Text editor for configuration
🔧 Pipeline Workflow The included Jenkinsfile demonstrates a complete distributed build: Stage 1: Maven Build (agentmaven)
Clones Spring PetClinic from GitHub Compiles Java application with Maven Packages JAR artifact Stashes artifact for later stages
Stage 2: Windows Tasks (windows)
Executes Windows-specific commands Demonstrates batch and PowerShell execution Archives task outputs
Stage 3: Docker Build (agentdocker)
Retrieves Maven-built artifact Creates dynamic Dockerfile Builds Docker image Pushes to Docker Hub
Stage 4: Deployment (agentdocker)
Deploys container from latest image Performs health checks Provides deployment status
🔒 Security Features
SSH Key Authentication: ED25519 keys for agent connections Least Privilege: Dedicated jenkins user accounts Controller Isolation: Executors disabled on controller Network Segmentation: Security groups restrict access Credential Management: Jenkins credential store integration
📊 Monitoring Health Checks
Jenkins UI: Node status indicators System logs: /var/log/jenkins/jenkins.log Agent logs: Individual agent log directories Container health: Docker health checks
Performance Metrics
Build execution times Agent utilization Resource consumption Network connectivity
🔄 Maintenance Regular Tasks
Update Jenkins and plugins Rotate SSH keys periodically Monitor disk space on agents Review security group rules Update base system packages
Backup Strategy
Jenkins configuration (JENKINS_HOME) SSH keys and certificates Pipeline definitions Agent configurations
