Running SonarQube Scanner on a Jenkins remote slave - jenkins

Question

I have a Docker container running Jenkins (2.150.1) and another Docker container running SonarQube (7.4). Jenkins is using the SonarQube Scanner for Jenkins plugin and the scanning is done on the Jenkins container. The Jenkinsfile for the project looks like this:
pipeline {
agent any
stages {
stage('Build') {
steps {
echo 'building...'
}
}
stage('Test') {
steps {
echo 'testing...'
withSonarQubeEnv ('SonarQube') {
sh '/var/jenkins_home/sonar-scanner/sonar-scanner-3.2.0.1227-linux/bin/sonar-scanner'
}
echo 'really finished testing2'
}
}
stage("Quality Gate") {
steps {
timeout(time: 1, unit: 'MINUTES') {
waitForQualityGate abortPipeline: true
}
}
}
stage('Deployment') {
steps {
echo 'deploying...'
}
}
}
}
To get the scanning to work as part of a Jenkins pipeline job, I manually installed sonar-scanner on the Jenkins container by downloading the zip file and unzipping it to: /var/jenkins_home/sonar-scanner/sonar-scanner-3.2.0.1227-linux
This is working well, but I want to improve it by:
taking out the harcoded path to sonar-scanner from my Jenkinsfile
specify a non local location of sonar-scanner because I now need to run the scan on another VM/container instead of on the Jenkins container
I tried using Manage Jenkins > Global Tool Configuration > SonarQube Scanner and updated my Jenkinsfile to use SONAR_RUNNER_HOME instead of the hard coded path, but that didn't work and I got an error that sonar-scanner can't be found.

Answer 1

In Manage Jenkins > Global Tool Configuration > SonarQube Scanner check install automatically.
Then go to Manage Jenkins > Configure System and add the following
The Name should be the same as the parameter in the line in your Jenkinsfile: withSonarQubeEnv('SonarQube')
