9. Tip #6 pipeline { agent { docker 'maven:3-alpine' } stages { stage('Example Build') { steps { sh 'mvn -B clean verify' } } } } node { stage('Example') { try { sh 'exit 1' } catch (exc) { echo 'Something failed, I should sound the klaxons!' throw exc } } } Declarative Pipeline Scripted Pipeline
10. Tip #7 Ask for user authorization on sensitive operations timeout(time:5, unit:'HOURS') { input message: ‘Deploy to production?', ok: 'Deploy!' } http://jenkins508.rssing.com/chan-25443405/all_p18.html
11. Tip #8 Integrate slack
12. Tip #9 Make the pipeline fast stage("Testing: phase a") { parallel 'JUnit': { stage("junit") { sh '...' } }, 'Deploy to simulator': { stage("Deploy to simulator") { sh '...' } } }
