Jenkins CD

Configure Jenkins Pipeline stages for application deployments. This skill covers deployment patterns, credential management, deployment targets, and strategies for safe production rollouts.

Quick Start

Basic Deployment Stage Pattern

pipeline {
  agent any
  stages {
    stage('Deploy to Staging') {
      steps {
        sh 'kubectl apply -f staging-deployment.yaml'
        sh 'kubectl rollout status deployment/app -n staging'
      }
    }
    stage('Approval Gate') {
      steps {
        input message: 'Approve production deployment?', ok: 'Deploy'
      }
    }
    stage('Deploy to Production') {
      steps {
        sh 'kubectl apply -f prod-deployment.yaml'
      }
    }
  }
}

Input Step for Approval

stage('Promote to Production') {
  steps {
    input(
      id: 'approve',
      message: 'Deploy to production?',
      ok: 'Deploy',
      submitter: 'admin-group'
    )
    echo 'Approved by: ${APPROVED_BY}'
  }
}

Lockable Resources Plugin

stage('Deploy Database') {
  steps {
    lock('prod-database') {
      sh 'flyway migrate -schemas=public -locations=filesystem:./migrations'
    }
  }
}

Credentials Binding

stage('Deploy') {
  steps {
    withCredentials([
      usernamePassword(credentialsId: 'docker-hub', usernameVariable: 'DOCKER_USER', passwordVariable: 'DOCKER_PASS'),
      string(credentialsId: 'slack-token', variable: 'SLACK_TOKEN')
    ]) {
      sh '''
        echo $DOCKER_PASS | docker login -u $DOCKER_USER --password-stdin
        docker push myapp:latest
      '''
    }
  }
}

Post-Deploy Health Check

stage('Verify Deployment') {
  steps {
    retry(3) {
      sh 'curl -f http://app-prod:8080/health || exit 1'
    }
  }
  post {
    failure {
      sh 'kubectl rollout undo deployment/app -n production'
    }
  }
}
