39. • Declarative Pipeline
• “script” Scripted
Pipeline

40. Declarative Pipeline
Examples

41. Build in Container
// simple
agent {
docker “ubuntu:16.04”
}
// specify label & args
agent {
docker {
image “ubuntu:16.04”
label “docker-nodes”
args “-v /tmp:/tmp -p 8000:8000”
}
}

42. Credentials

43. Credentials
environment {
// type: secret text
// SECRET_TEXT is defined
SECRET_TEXT = credentials(‘SECRET_TEXT')
// type: username and password
// SECRET_AUTH_USR and SECRET_AUTH_PSW are defined
SECRET_AUTH = credentials('SECRET_AUTH')
}

44. Options
pipeline {
options {
// 7
buildDiscarder(logRotator(daysToKeepStr: '7'))
}
}

45. Triggers
pipeline {
triggers {
cron('* * * * *')
}
}

46. Parallel
stage("Commit") {
steps {
parallel(
unitTest: {
…
},
staticAnalysis: {
…
},
package: {
…
}
)
}
}

47. Conditions
stage("Production") {
when {
branch "master"
}
steps {
// deploy to production
}
}

48. Stash
stage("Archive") {
agent {
docker “java:8”
}
steps {
sh “gradle jar”
stash name: “jar”, includes: “build/libs/*.jar”
}
}
stage(“Deployment”) {
agent {
docker …
}
steps {
unstash “jar”
// jar
}
}

49. User Input
stage("Production") {
steps {
input “Ready to deploy?”
}
}

52. Shared Libraries

• subtree or submodule…?
Jenkins 1.0

54. Shared Libraries
• GitHub
• Groovy
• https://jenkins.io/doc/book/pipeline/shared-
libraries/
Jenkins 2.0

55. Example: without Library
pipeline {
…
post {
failure {
// echo ‘failure!’ with red color
ansiColor('xterm') {
echo '033[0;31mFailure!033[0m'
}
}
}
…
}

56. vars/echoErr.groovy
#!/usr/bin/env groovy
def call(String text) {
ansiColor('xterm') {
echo “033[0;31m${text}033[0m"
}
}

58. (repository root)
+- vars
- +- echoErr.groovy

59. Example: with Library
@Library('miyata-shared-libraries') _
pipeline {
…
post {
failure {
echoErr ‘Failure!’
}
}
…
}
