Jenkins Pipeline for Microservice Deployment

This Jenkins pipeline automates the deployment process of a microservice, including building a Docker image, pushing it to AWS ECR, performing SonarQube analysis for both .NET and PHP, and finally deploying the microservice using Kubernetes.

Prerequisites

• Jenkins installed and configured
• AWS ECR repository set up
• SonarQube server configured for the projects
• Kubernetes cluster configured and accessible

Jenkins Pipeline Stages

1. Build Docker Image

This stage builds the Docker image for the microservice.

• Agent: Any
• Environment Variables:
  • MICROSERVICE_NAME
  • IMAGE_REGISTRY
  • TAG

2. Push to AWS ECR

This stage pushes the Docker image to AWS ECR.

• Agent: Any
• Environment Variables:
  • AWS_REGION
  • AWS_ACCOUNT_ID

3. SonarQube Analysis for .NET

This stage performs SonarQube analysis for a .NET Core project.

• Agent: Any
• Environment Variables:
  • MICROSERVICE_NAME
  • SONARQUBE_URL
  • SONARQUBE_LOGIN

4. SonarQube Analysis for PHP

This stage performs SonarQube analysis for a PHP project using Composer.

• Agent: Any
• Environment Variables:
  • MICROSERVICE_NAME
  • SONARQUBE_URL
  • SONARQUBE_LOGIN

5. Deploy

This stage deploys the microservice to a Kubernetes cluster.

• Agent: Any
• Environment Variables:
  • MICROSERVICE_NAME
  • REPLICAS
  • IMAGE_REGISTRY
  • TAG
  • CONTAINER_PORT
  • SERVICE_PORT

Post-build Action

• Display SonarQube Results:
  • Displays the SonarQube analysis results in the Jenkins console.

How to Use

1. Configure the required environment variables in the Jenkins pipeline configuration.
2. Run the Jenkins pipeline.

Setting Up SonarQube for Code Analysis

1. Install and configure SonarQube on your server or use the SonarQube cloud service.
2. Follow the official SonarQube documentation for installation: SonarQube Installation Guide.
3. Create a new project in SonarQube and generate a token for authentication.
4. Set up SonarQube for .NET by installing the SonarScanner for .NET: SonarScanner for .NET Documentation.
5. Set up SonarQube for PHP by installing the SonarScanner for PHP: SonarScanner for PHP Documentation.
6. Configure your Jenkins pipeline with the SonarQube server URL and authentication token.

Deployment File Explanation

Deployment Section apiVersion: Specifies the Kubernetes API version for the resource.

kind: Defines the type of resource, in this case, a Deployment.

metadata: Contains metadata such as the name and labels for the Deployment.

spec: Describes the desired state for the Deployment, including the number of replicas and the pod template.

replicas: Specifies the desired number of replicas for the microservice.

selector: Defines how the Deployment identifies which pods to manage.

template: Defines the pod template, including labels and specifications for the containers.

containers: Contains information about the microservice container.

name: Specifies the name of the container. image: Specifies the Docker image for the microservice. ports: Specifies the container port to expose. livenessProbe: Configures the liveness probe for the container.

readinessProbe: Configures the readiness probe for the container.

Service Section kind: Defines the type of resource, in this case, a Service.

apiVersion: Specifies the Kubernetes API version for the resource.

metadata: Contains metadata such as the name for the Service.

spec: Describes the desired state for the Service.

selector: Specifies the pods that the Service should target. ports: Specifies the ports for the Service, including the protocol, port, and target port.
