gitlab+jenkins+docker+kubernetes 实现容器自动化部署

1 环境准备

192.168.58.128k8s(master节点)
192.168.58.129k8s(node1节点)
192.168.58.130k8s(node2节点)
192.168.58.131jenkins-agent节点
192.168.58.132gitlab
192.168.58.133jenkins 节点

jenkins-agent 节点需要安装 jdk  maven git ，这台机器用于拉取代码  构建代码 

部署采用流水线的方式部署

jenkins 配置

配置从节点 

jenkins-agent节点  和master 节点进行免密登录

jenkins-agent节点

保存

新建流水线测试：

测试打印输出192.168.58.131 的hostname

保存  立即构建

控制台输出

拉取代码

片段生成器生成拉取git 代码的命令

  1. pipeline {
  2.     agent {
  3.   label 'jenkins-pipeline-k8s-131'
  4. }
  5.  
  6.  
  7.     stages {
  8.         stage('环境测试') {
  9.             steps {
  10.                sh '''java -version
  11.                 git version
  12.                 docker -v
  13.                 mvn -v'''
  14.             }
  15.         }
  16.         
  17.          stage('拉取代码') {
  18.             steps {
  19.               checkout scmGit(branches: [[name: '*/master']], extensions: [], gitTool: '', userRemoteConfigs: [[credentialsId: '698f26a1-7b10-4cef-8f06-ccf0bf7fd96c', url: 'ssh://git@192.168.58.132:222/root/jenkinsdemo.git']])
  20.             }
  21.         }
  22.     }
  23. }

保存立即构建

构建时有可能会报如下错误：

此错误是因为在192.168.58.131 上找不到git 命令，解决方法为在节点信息中添加git 的目录

重新构建

构建成功

代码存在工作目录下

构建代码

会在相应的目录生成target 文件

构建镜像

此处在工程里边引用了dockerfile插件直接推送的harbor仓库
