Jenkins ver. 2.150.1
Kubernetes Plugin: 1.13.2
Problem Statement
The build hangs when using inheritFrom in a declarative pipeline (have not tested in a script pipeline) and you either
- set an identical label to the one defined in the Pod Template
- omit the label tag meaning the inherited label is used (i.e. also identical)
The problem is, however, that there is no information that something is wrong. The build just hangs.
To Reproduce
Use the following (uncomment label to make it work):
pipeline {
agent {
kubernetes {
inheritFrom 'nodejs'
// THIS WOULD FAIL --> label 'jenkins-nodejs'
// THIS WOULD BE OK --> label 'my-agent'
containerTemplate {
name 'nodejs'
image 'jenkinsxio/builder-nodejs8x:0.1.187'
}
defaultContainer 'nodejs'
}
}
stages {
stage('Npm Check') {
steps {
sh 'npm -v'
}
}
}
post {
always {
cleanWs()
}
}
}
