Jenkins Declarative Pipeline. Stages, agents, post actions.

Jenkinsfile¶

pipeline {
    agent any
    stages {
        stage('Test') { steps { sh 'npm ci && npm test' } }
        stage('Build') { steps { sh 'docker build -t myapp:${BUILD_NUMBER} .' } }
        stage('Deploy') {
            when { branch 'main' }
            steps { sh 'kubectl set image deploy/app app=myapp:${BUILD_NUMBER}' }
        }
    }
    post { failure { slackSend channel: '#ci', message: 'Build failed!' } }
}

Summary¶

Jenkins is flexible but requires maintenance. For new projects, consider GitHub Actions or GitLab CI.
