Kubernetes 的 Jenkins 插件的容器问题

Question

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?

Answer 1

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
                    '''
                }
            }
        }
    }
}
