Declarative Groovy Pipeline

 

-- A Sample Declarative Pipeline - Build, test and , build docker image , update GitOps repository

pipeline {
    agent any
    
    environment {
        DOCKER_REGISTRY = "your-docker-registry-url"
        GITOPS_REPO = "your-gitops-repo-url"
        GITOPS_BRANCH = "main"
    }
    
    stages {
        stage('Build and Test') {
            steps {
                // Checkout your source code from version control
                checkout scm
                
                // Run tests, build binaries, etc.
                sh 'make test'
            }
        }
        
        stage('Build Docker Image') {
            steps {
                script {
                    def dockerImageTag = "test-${env.BUILD_NUMBER}"
                    
                    // Build Docker image
                    sh "docker build -t ${DOCKER_REGISTRY}/your-image-name:${dockerImageTag} ."
                    
                    // Push Docker image to the registry
                    sh "docker push ${DOCKER_REGISTRY}/your-image-name:${dockerImageTag}"
                    
                    // Save the image tag for deployment
                    env.DOCKER_IMAGE_TAG = dockerImageTag
                }
            }
        }
        
        stage('Update GitOps Repository') {
            steps {
                script {
                    // Clone the GitOps repository
                    sh "git clone ${GITOPS_REPO} gitops-repo"
                    dir("gitops-repo") {
                        // Update the deployment file with the new image tag
                        sh "sed -i 's#image: your-image-name:.*#image: ${DOCKER_REGISTRY}/your-image-name:${env.DOCKER_IMAGE_TAG}#' deployment.yaml"
                        
                        // Commit and push changes
                        sh "git add deployment.yaml"
                        sh "git commit -m 'Update deployment with new image tag'"
                        sh "git push origin ${GITOPS_BRANCH}"
                    }
                }
            }
        }
    }
    
    post {
        always {
            // Cleanup Docker images and containers
            sh 'docker system prune -af'
        }
    }
}

Remember to replace placeholders like your-docker-registry-url, your-gitops-repo-url, your-image-name, and update the steps based on your build and deployment process. This pipeline assumes you have the necessary Docker and Git credentials configured in your Jenkins instance. Additionally, make sure to adjust error handling, security, and other considerations to meet your specific requirements.
