This project aims to optimize the software development lifecycle by leveraging Jenkins for continuous integration and continuous delivery (CI/CD) processes, integrated with Docker for containerization. By automating build, test, and deployment workflows, we enhance efficiency and productivity in software development.

1. Provision EC2 Instance:

   • Set up an Amazon EC2 instance to serve as the development environment.
   • Ensure the instance meets the requirements for running Java, Jenkins, and Docker.

2. Install Prerequisites:

   • Install Java:
     • Install the latest version of Java Development Kit (JDK) compatible with Jenkins.
   • Install Jenkins:
     • Follow the official installation guide to install Jenkins on the EC2 instance.
   • Install Docker:
     • Follow the Docker installation instructions for your operating system.

3. Configure Jenkins:

   • Access the Jenkins dashboard using the EC2 instance's public IP address and port.
   • Set up Jenkins using the initial setup wizard, configuring admin credentials and plugins.
   • Install required plugins:
     • Navigate to Jenkins > Manage Jenkins > Manage Plugins and install the Docker plugin.
   • Configure Jenkins for CI/CD:
     • Set up Jenkins credentials to access version control repositories.
     • Configure Jenkins to trigger builds automatically upon code commits.

4. Integrate Docker:

   • Install Docker plugin in Jenkins:
     • Navigate to Jenkins > Manage Jenkins > Manage Plugins and install the Docker plugin.
   • Grant necessary permissions:
     • Ensure Jenkins has the necessary permissions to interact with Docker by adding the Jenkins user to the Docker group.
     • Run the following command: sudo usermod -aG docker jenkins
   • Configure Docker Cloud in Jenkins:
     • Navigate to Jenkins > Manage Jenkins > Configure System and configure Docker Cloud using the Docker plugin.

1. Jenkins Pipeline:

   • Define CI/CD pipelines using Jenkinsfile:
     • Create a Jenkinsfile at the root of your project repository.
     • Define pipeline stages and steps using declarative or scripted syntax.
   • Customize pipeline stages:
     • Define stages for build, test, and deployment.
     • Use Docker containers within pipeline stages for isolated execution environments.

2. Docker Integration:

   • Utilize Docker containers:
     • Dockerize your applications and services to create lightweight, portable containers.
     • Use Docker images for packaging and distributing applications.
   • Orchestrate Docker commands in Jenkins:
     • Use Docker commands within Jenkins pipeline stages to build, tag, and push Docker images.

3. Automation:

   • Implement Jenkinsfile:
     • Define CI/CD pipelines as code using Jenkinsfile to automate the entire software delivery process.
   • Automate workflows:
     • Automate the execution of build, test, and deployment tasks within Jenkins pipelines.
     • Configure pipeline triggers to automatically start builds upon code changes.

The Jenkinsfile, located at Jenkinsfile, defines the CI/CD pipeline as code. This file orchestrates the entire build, test, and deployment process within Jenkins. Please refer to the Jenkinsfile for details on pipeline stages and steps.

• Explore further automation opportunities:
  • Implement advanced pipeline features such as parallel stages and error handling.
  • Integrate additional tools and services for enhanced CI/CD workflows.
• Continuous optimization:
  • Continuously refine CI/CD processes to improve efficiency and reliability.
  • Monitor pipeline performance and identify areas for optimization.
