===== Jenkinsfiles =====
==== Basic one ====
pipeline {
agent any
stages {
stage ('Initialize') {
steps {
echo 'Place'
echo 'holder'
}
}
}
}
=== Correr una pipeline en contenedor ===
Simplemente has de seleccionar el agente docker:
pipeline {
agent {
docker { image 'node:14-alpine' }
}
stages {
stage('Test') {
steps {
sh 'node --version'
}
}
}
}
=== Correr pipeline en varios contenedores ===
pipeline {
agent none
stages {
stage('Back-end') {
agent {
docker { image 'maven:3-alpine' }
}
steps {
sh 'mvn --version'
}
}
stage('Front-end') {
agent {
docker { image 'node:14-alpine' }
}
steps {
sh 'node --version'
}
}
}
}
=== Los últimos pasos con post ===
pipeline {
agent any
stages {
stage('Test') {
steps {
sh 'echo "Fail!"; exit 1'
}
}
}
post {
always {
echo '[*] This will always run'
}
success {
echo '[*] This will run only if successful'
}
failure {
echo '[*] This will run only if failed'
}
unstable {
echo '[*] This will run only if the run was marked as unstable'
}
changed {
echo '[*] This will run only if the state of the Pipeline has changed'
echo '[*] For example, if the Pipeline was previously failing but is now successful'
}
}
}

* ''checkout scm'' para obtener el código del SCM.
* ''sh'' para ejecutar un comando shell.

* ''echo'' para escribir.
=== Definir variables ===
def docker_registry = 'https://118864902010.dkr.ecr.us-east-1.amazonaws.com';
=== String format ===
def docker_registry = 'https://118864902010.dkr.ecr.us-east-1.amazonaws.com';
def docker_registry_credential = 'ecr:us-east-1:AWSJenkins';
pipeline {
agent any
environment {
PYPI_CREDS = credentials('pip_jenkins')
}
stages {
stage('Clone') {
steps {
echo docker_registry
echo "a: ${docker_registry}" // Importarte las dobles comillas
}
}
}
}
=== Definir funciones ===
...
post {
failure {
notifyBuild(currentBuild.result);
}
}
...
def notifyBuild(String buildStatus = 'STARTED') {
// build status of null means successful
buildStatus = buildStatus ?: 'SUCCESSFUL'
// Default values
def recipientProviders = [[$class: 'DevelopersRecipientProvider']]
def colorName = 'RED'
def colorCode = '#FF0000'
def subject = "${buildStatus}: ${env.JOB_NAME} #${env.BUILD_NUMBER}"
def summary = "${subject} (${env.BUILD_URL})"
def details = """STARTED: Job '${env.JOB_NAME} [${env.BUILD_NUMBER}]':
Check console output at "${env.JOB_NAME} [${env.BUILD_NUMBER}]"
"""
// Override default values based on build status
if (buildStatus == 'STARTED') {
color = 'YELLOW'
colorCode = '#FFFF00'
} else if (buildStatus == 'SUCCESSFUL') {
color = 'GREEN'
colorCode = '#00FF00'
} else {
color = 'RED'
colorCode = '#FF0000'
recipientProviders = [[$class: 'CulpritsRecipientProvider'], [$class: 'RequesterRecipientProvider']]
}
// Send notifications
slackSend(color: colorCode, message: summary)
emailext(
subject: "[Jenkins] ${subject}",
mimeType: 'text/html',
body: '''${JELLY_SCRIPT,template="html"}''',
recipientProviders: recipientProviders
)
}
===== Gotchas =====
==== Jenkins runner ====
There is a Visual Studio Code extension called Jenkins runner: https://marketplace.visualstudio.com/items?itemName=dave-hagedorn.jenkins-runner
Thanks to that extension we will be able to directly run local code into a Jenkins task. However, you will need to previously configure the extension. For that, lets imagine an existent Jenkins pipeline called `testpipeline`. You would open your Visual Studio Code settings file and add the next configuration:
"jenkins-runner.hostConfigs": {
"local": {
"url": "http://127.0.0.1:8080",
"user": "your-jenkins-user",
"password": "your-password"
}
},
"jenkins-runner.jobs": {
"job-testpipeline": {
"isDefault": true,
"runWith": "local",
"name": "testpipeline",
},
}
Locally you would create a Jenkinsfile like this example:
pipeline {
agent any
stages {
stage ('Initialize') {
steps {
echo 'Hello Jenkins!'
}
}
}
}
If we do ''ctrl+shift+p'' there will appear a menu where we can select ''Jenkins runner: Run pipeline script on a default job''. Doing that you should see what Jenkins says in the same Visual Studio Code output window.
