Complete CI/CD with Jenkins and ArgoCD

Introduction

Welcome to my project that exemplifies the implementation of Continuous Integration and Continuous Deployment (CI/CD) practices. In this project, I have leveraged the power of Jenkins and ArgoCD to automate and streamline the entire software delivery/deployment pipeline.

With CI/CD, it eliminates the manual steps and enabled the automatic build, test, and deployment of our applications. This ensures faster release cycles, higher quality code, and improved collaboration among team members.

To ensure code quality, I have integrated SonarQube in pipeline. It performs static code analysis and provides valuable insights into potential issues, bugs, and vulnerabilities. By addressing these concerns early in the development process, we can deliver more robust and secure applications.

Furthermore, this project embraces containerization using Kubernetes for deployment. Kubernetes allows us to efficiently manage and scale our application containers, ensuring high availability and seamless updates.

By combining the power of Jenkins, ArgoCD, SonarQube, and Kubernetes, I have created an end-to-end CI/CD solution that significantly enhances the development process, accelerates delivery, and improves the overall quality of our software.

Features

• A configured CI/CD pipeline for automated building, testing, and deployment
• Jenkins is used for automating the build and deployment process.
• Static Code Analysis using SonarQube
• GitOps enabled - Utilizes Argo CD for Kubernetes-based deployment
• Dockerized application for easy deployment and scalability

Prerequisites

Before getting started with this project, ensure you have the following dependencies installed:

• Docker
• Kubernetes Cluster (either local or on Cloud)
• SonarQube server up and running
  • Refer the documentation to configure SonarQube
• Ngrok (Running SonarQube in Docker on local machine)
• Argo CD installed

Getting Started

Setup the Project

To get started with this project, follow these steps:

Clone the repository:

• Application source code and CI part:

git clone https://github.com/sushank3/CI_CD-portfolio.git

• Kubernetes manifests file.

    git clone https://gitlab.com/sushank3/ci_cd-portfolio.git

1. Move to project home directory:

   mvn clean package
   or
   mvn clean install
   

   Java version >= 17

2. Run the application:

   • Option 1: Run locally

     ./mvnw spring-boot:run
     

   • Option 2: Run with Docker

     1. Build the image locally:

        docker build . -t <image tag>
        

     2. Run the docker container:

        docker run -d -p 8085:8080 <image>
        

• You can now access the app at: http://localhost:8085

  

Overview of CI/CD Workflow

Jenkins CI - Continuous Integration

Refer the Jenkinsfile for the full configuration.

Prerequisites

• Setup the following environment variables:
  • gitlab-token - Gitlab access token
  • docker_hub - DockerHub access token
  • sonarqube - SonarQube token
  • slack-jenkins - Slack token

The CI pipeline consists of 5 stages: stage('Build and Test') stage("Static Code Analysis") stage("Build docker file and push") stage('Update Deployment File')

1. Build - Builds the springboot application.
2. test - Static code analysis using SonarQube
3. Build docker file and push - Builds a new docker image and push to DockerHub
4. Update_k8s_manifests - Updates the latest image tag in Kubernetes manifests

📍NOTE:

The CI pipeline is configured to be triggered "on push" to the project. There are two conditions defined:

Steps to run SonarQube Locally (Linux)

apt install unzip

adduser sonarqube

wget https://binaries.sonarsource.com/Distribution/sonarqube/sonarqube-9.4.0.54424.zip

unzip *

chmod -R 755 /home/sonarqube/sonarqube-9.4.0.54424

chown -R sonarqube:sonarqube /home/sonarqube/sonarqube-9.4.0.54424

cd sonarqube-9.4.0.54424/bin/linux-x86-64/

./sonar.sh start

You can access the SonarQube Server on http://<ip-address>:9000

If you are using SonarQube in Docker:

You need to expose the Sonar Server using a tool like Ngrok, for GitLab to communicate with it.

Steps to run SonarQube on Docker:

docker run -d --name sonarqube -p 9000:9000 sonarqube

Setup ngrok for port mapping of sonarqube docker container:

ngrok http 9000

Refer the documentation for more information.

Refer the guide to know more about using Ngrok and Docker together.

Argo CD - Continuous Deployment

Refer the argCD.yaml for full application configuration for Argo CD.

A few important points for configuring Argo CD:

1. Argo CD will automatically sync the application and deploy it based on the configuration defined:

   syncPolicy:
       automated: {}
   
   

2. Monitor the deployment status and access the application once it's successfully deployed.

   

📍 To learn more about Argo CD and configure it in your cluster, refer the documentation.
