Jenkins CI/CD Server Deployment using Docker

Overview

This project demonstrates the deployment of Jenkins, a widely used continuous integration and continuous delivery (CI/CD) automation server, using Docker. The setup provides a reproducible, isolated, and persistent environment for running Jenkins locally.

Architecture

• Jenkins container running inside Docker
• Named Docker volume for persistent storage
• Port mapping for web interface and agent communication

Tools and Technologies

• Docker Engine
• Docker Compose
• Jenkins LTS

Setup Instructions

View Logs

docker logs jenkins-server

Observations

• Jenkins container deployed successfully
• Accessible via browser
• Persistent data storage implemented
• Plugins installed and user configured

Conclusion

This setup demonstrates containerized Jenkins deployment using Docker and forms a base for CI/CD pipeline implementation.
