Environment:
Jenkins - Version 2.235.5 (LTS)
Kubernetes Jenkins Plugin - 1.27.7
K8s-Master & Worker Server Details:-
OS - CentOS Linux release 7.9.2009 (Core) & Kernal - 3.10.0-1160.6.1.el7.x86_64
Docker Version - 19.03.12
Client Version: v1.19.0
Server Version: v1.19.0
我正试图登上一座
hostPathVolume
通过Jenkins Kubernetes插件
podTemplate
当吊舱通过Jenkins启动时,掌握我的K8s工作人员没有安装在K8s吊舱上的路径(Jenkins代理)。
我有下面的脚本管道。
podTemplate(label: 'mypod', containers: [
containerTemplate(name: 'git', image: 'ubuntu/16.04', ttyEnabled: true, command: 'cat'),
containerTemplate(name: 'maven', image: 'ubuntu/16.04', command: 'cat', ttyEnabled: true)
],
volumes: [
hostPathVolume(mountPath: '/var/run/docker.sock', hostPath: '/var/run/docker.sock'),
]
) {
node('mypod') {
stage('Check running containers') {
container('docker') {
// example to show you can run docker commands when you mount the socket
sh 'hostname'
sh 'hostname -i'
sh 'docker ps'
}
}
..... further stages....

安装在(
Jenkins master, K8s Master and K8s-Worker
)系统也重新启动了所有三个系统,但仍然没有成功。
我希望这个音量能安装在我的播客里,我已经试过了
K8s v1.19.4
和
Kubernetes Jenkins Plugin - 1.27.0
.不确定是什么原因导致
CentOS-7.9
.而同样的方法在
CentOS - 8.2.2004 (Core) & 4.18.0-193.14.2.el8_2.x86_64
K8s主机本机操作系统的内核。
