I already wrote an example Jenkinsfile to checkout and build and deploy a signal project. Is there a way to do all these for multiple project in different git repo the same time just using one Jenkinsfile ? I know I can set up these projects as independent jobs and use a Jenkinsfile to call them,but I'm wondering if I can do this without independent jobs.
Thanks.
You can make use of Job DSL Plugin to achieve this.
Jenkins Job DSL API will help you to write DSL scripts. You can find all the built-in DSL methods that will be needed to construct jobs.
Example pipeline script:
pipeline {
agent any
stages {
stage('Job1') {
steps {
//Pipeline Job
jobDsl scriptText: '''pipelineJob(\"$job1\") {
definition {
cpsScm {
scm {
git {
remote{
name('origin')
url('https://github.com/satta19/user-node.git')
credentials('git2-cred')
}
branch ('master')
}
}
scriptPath('Jenkinsfile')
}
}
}'''
}
}
stage('Job2') {
steps {
//Freestyle job
jobDsl scriptText: '''job(\"$job2\") {
steps {
shell(\'echo Hello World!\')
}
}'''
}
}
}
}
Note: I have taken the jobs name as string parameter i.e. $job1 and $job2 in the above example pipeline script.
Beginner in Jenkins. I have set up Jenkins on Linux server and creating a pipeline. I see in a Pipeline Tab, where it asks pipeline script or pipeline script from SCM. i m not using any SCM. i have written the sample pipeline script
pipeline {
agent {
node {
label ''
}
}
stages {
stage ('check script')
{
steps
{
script
{
println " Checking the bounce scripts of application"
}
}
}
stage ('Bounce Application')
{
steps
{
script
{
println " Bouncing the application"
}
}
}
}
}
i wanted to put the above pipeline script in a file on a Jenkins server and use/ call it here. Do we have feasibility of this?
Thanks for your help in advance.
I am building a test system with Jenkins with multiple slave nodes. I have multiple test cases where each of them take at more than 15 minutes to run.
I want to make the system in a way that when I start tests Jenkins running each test case in a node which is free and at the end collects and summarizes the test results.
I have opened a Jenkins job which is general test-case job and it is parametrized where the parameter is the "test name". But I see that Jenkins is executing the jobs sequentially.
How can I configure Jenkins to run builds for the same job (with different parameters) in parallel?
simple syntax for parallel:
pipeline {
stages {
stage('Run Tests In Parallel') {
parallel {
stage('Projects Test 1') {
agent {
node { label "your jenkins label" }
}
steps{
script {
your test 1
}
}
post{
always {
script {
echo ' always'
}
}
}
}
stage('Projects Test 2') {
agent {
node { label "your jenkins label" }
}
steps{
script {
your test 2
}
}
post{
always {
script {
echo ' always'
}
}
}
}
}
}
}
}
Hi you can use parallel stages in jenkins which runs parallely. also use agent any at each stage so it will use any free node.
Check Parallel Stages document for more info
I want to run Jenkins scripted pipeline job at the specified slave at the moment when no other job is running on it.
After my job will be started, no other jobs should be performed on this slave, they will have to wait for my job ending running
All the tutorials that I found allowed me to run job on the node when it is free but did not protect me from launching other jobs on this node
Could you tell me how can I do this?
Because Pipeline has two Syntax, there are two ways to achieve that. For scripted pipeline please check the second one.
Declarative
pipeline {
agent none
stages {
stage('Build') {
agent { label 'slave-node' }
steps {
echo 'Building..'
sh '''
'''
}
}
}
post {
success {
echo 'This will run only if successful'
}
}
}
Scripted
node('your-node') {
try {
stage 'Build'
node('build-run-on-this-node') {
sh ""
}
} catch(Exception e) {
throw e
}
}
I'm building jobs that will be using Jenkins piplines extensively. Our nodes are designated per project by their tags, but unlike regular jobs the pipeline build does not seem to have the "Restrict where this project can be run" checkbox. How can I specify on which node the pipeline will run the way I do for regular jobs?
You specify the desired node or tag when you do the node step:
node('specialSlave') {
// Will run on the slave with name or tag specialSlave
}
See https://jenkins.io/doc/pipeline/steps/workflow-durable-task-step/#node-allocate-node for an extended explanation of the arguments to node.
Edit 2019: This answer (and question) was made back in 2017, back then there only was one flavor of Jenkins pipeline, scripted pipeline, since then declarative pipeline has been added. So above answer is true for scripted pipeline, for answers regarding declarative pipeline please see other answers below.
Choosing a node which has the label X in a declarative pipeline with json format:
pipeline {
agent { label 'X' }
...
...
}
You also can apply multiple labels with or (||) or with and (&&) operator.
Running the job on any of the nodes which has label X or label Y:
agent { label 'X || Y' }
Running the job only on nodes which have both label:
agent { label 'X && Y' }
More in the Jenkins Pipeline reference guide.
ps: if you are reading this you probably have just started using Jenkins pipeline and you are not sure if you should use declarative or scripted pipeline. Short answer: it's better to start with declarative. From jenkins.io:
Declarative and Scripted Pipelines are constructed fundamentally
differently. Declarative Pipeline is a more recent feature of Jenkins
Pipeline which:
provides richer syntactical features over Scripted Pipeline syntax, and
is designed to make writing and reading Pipeline code easier.
To be clear, because Pipeline has two Syntax, there are two ways to achieve that.
Declarative
pipeline {
agent none
stages {
stage('Build') {
agent { label 'slave-node' }
steps {
echo 'Building..'
sh '''
'''
}
}
}
post {
success {
echo 'This will run only if successful'
}
}
}
Scripted
node('your-node') {
try {
stage 'Build'
node('build-run-on-this-node') {
sh ""
}
} catch(Exception e) {
throw e
}
}
Agent or Node where we should not execute the jenkins job :
This is the negation of the problem statment i.e. node where not to run
It was most weird solution to me but issue has been already raised to jenkins community
agent { label '!build-agent-name' }
If you need to run entire jenkins pipeline to run on single node, use the following format
pipeline {
agent {
label 'test1'
}
stages {
stage('Build') {
steps {
echo 'Building..'
}
}
stage('Test') {
steps {
echo 'Testing..'
}
}
stage('Deploy') {
steps {
echo 'Deploying....'
}
}
}
}
if you need to execute each stage in different nodes, use the below format,
pipeline {
agent any
stages {
stage('Build') {
steps {
echo 'Building..'
}
}
stage('Test') {
steps {
node("test1"){
echo 'Testing..'
}
}
}
stage('Deploy') {
steps {
echo 'Deploying....'
}
}
}
}
