Jenkins - Pipeline

Card Puncher Data Processing


The pipeline step allows you to define your Pipelines in a more structured way.

Pipelines are a series of steps that allow you to orchestrate the work required to build, test and deploy applications. Pipelines are defined in a file called Jenkinsfile that is stored in the root of your project’s source repository.

Pipeline syntax validation (ie Linting) via HTTP POST using curl from Pipeline Dev tool

# curl (REST API)
# User

# Api key from "/me/configure" on my Jenkins instance
JENKINS_USER_KEY=--my secret, get your own--

# Url for my local Jenkins instance.

# JENKINS_CRUMB is needed if your Jenkins master has CRSF protection enabled (which it should)
JENKINS_CRUMB=`curl "$JENKINS_URL/crumbIssuer/api/xml?xpath=concat(//crumbRequestField,\":\",//crumb)"`
curl -X POST -H $JENKINS_CRUMB -F "jenkinsfile=<Jenkinsfile" $JENKINS_URL/pipeline-model-converter/validate

  • agent instructs Jenkins to allocate an executor (on any available agent/node in the Jenkins environment) and workspace for the entire Pipeline.
  • node effectively does the same as agent
  • echo writes simple string in the console output.

  agent { docker 'maven:3.3.3' }

      steps {
        sh 'mvn --version'
