I'm using kubernetes plugin in jenkins. I'm trying to use it with Pipeline and Freestyle jobs. The jobs are running, but only in container with name jnlp-slave:3.35-5-alpine which I did't define anywhere.
Even if define the image in the pipeline nothing happanig and still running in this jnlp-slave:3.35-5-alpine image. Here is example of my pipeline:
pipeline {
agent none
stages {
stage ('Stage as dsl') {
agent {
kubernetes {
cloud 'kubernetes'
label 'jnlp-slave'
containerTemplate {
name 'jnlp-slave'
image 'jnlp-slave'
}
}
}
steps {
sh '''
pwd; \
whoami; \
uname -a
'''
}
}
}
}
Where is my mistake?
The solution that I find is to NOT define any label for the cluster.
In my jenkinsfile example I'm testing to use diffrend docker images like this:
Working Solution
def podTemplate = """
apiVersion: v1
kind: Pod
spec:
containers:
- name: java-slave
image: myrepo/java-slave:latest
command:
- sleep
args:
- infinity
- name: jenkins-slave-dind
image: myrepo/jenkins-slave-dind:latest
command:
- sleep
args:
- infinity
volumeMounts:
- name: dockersock
mountPath: /var/run/docker.sock
volumes:
- name: dockersock
hostPath:
path: /var/run/docker.sock
"""
pipeline {
agent {
kubernetes {
yaml podTemplate
defaultContainer 'java-slave'
}
}
stages {
stage('Main') {
steps {
sh 'curl google.com'
}
}
stage ('Stage as dsl 4'){
steps {
container('jenkins-slave-dind') {
sh '''
docker ps -a
'''
}
}
}
}
}
