Jenkins Pipeline 流水线 - K8S kubectl 升级
- 使用代理节点
- Remote SSH 远程执行命令进行升级
Remote SSH 方式
安装插件
- SSH Pipeline Steps
Pipeline SSH 脚本
credentialsId: 'K8SMaster'
pipeline { agent any stages { stage('Remote SSH') { steps { script { def remote = [:] remote.name = 'Test' remote.host = '172.16.3.181' remote.allowAnyHosts = true withCredentials([usernamePassword(credentialsId: 'K8SMaster', passwordVariable: 'password', usernameVariable: 'username')]) { remote.user = "${username}" remote.password = "${password}" } sshCommand remote: remote, command: "kubectl version" } } } } }
Pipeline Remote SSH K8S 升级
pipeline { agent any stages { stage('Remote SSH') { steps { script { def remote = [:] remote.name = 'Test' remote.host = '172.16.3.181' remote.allowAnyHosts = true withCredentials([usernamePassword(credentialsId: 'K8SMaster', passwordVariable: 'password', usernameVariable: 'username')]) { remote.user = "${username}" remote.password = "${password}" } sshCommand remote: remote, command: "kubectl set image deployment/javademo1 vipsoft=registry.cn-shanghai.aliyuncs.com/vipsoft/vipsoft:4.0" } } } } }
代理方式
新增K8S节点
注意JDK

Pipeline Script
pipeline { agent none stages { stage('代理节点运行') { agent { label 'K8SAgent' } //这边使用节点名称或节点标签，都可以运行 steps { sh 'kubectl set image deployment/javademo1 vipsoft=registry.cn-shanghai.aliyuncs.com/vipsoft/vipsoft:4.0' echo '构建完成' } } } }
