第一步，jenkins基础环境搭建

1，安装jenkins

docker run -d --name jenkins -p 80:8080 -p 50000:50000 -u root  \
   -v /opt/jenkins_home:/var/jenkins_home \
   -v /var/run/docker.sock:/var/run/docker.sock   \
   -v /usr/bin/docker:/usr/bin/docker \
   -v /usr/local/maven:/usr/local/maven \
   -v /usr/local/jdk:/usr/local/jdk \
   -v /etc/localtime:/etc/localtime \
   --name jenkins jenkins/jenkins:lts

2.选择插件安装，不安装任何插件，后面我们会替换源，推荐安装，经常出现安装错误，因为源是国外的

4，替换jenkins的配置文件的源

修改国内源：
cd /opt/jenkins_home/updates
sed -i 's/http:\/\/updates.jenkins-ci.org\/download/https:\/\/mirrors.tuna.tsinghua.edu.cn\/jenkins/g' default.json && \
sed -i 's/http:\/\/www.google.com/https:\/\/www.baidu.com/g' default.json
然后重启jenkins容器生效。

5，安装插件 Git  和 Pipeline

6.配置git和harbor 的凭证

 

二，创建一个golang的项目

2.1 传入pipeline的参数Branch函数，master分支，‘发布代码分支’注释

2.2，写pipeline脚本

 

#!/usr/bin/env groovy

def registry = "10.1.1.11"
def project = "datacenter"
def app_name = "zhiyuecms"
def image_name = "${registry}/${project}/${app_name}:${Branch}-${BUILD_NUMBER}"
def git_address = "http://10.1.1.11:9999/golang/zhiyuecms.git"
def docker_registry_auth = "e94b8182-3024-42be-945b-1c6e3616e337"
def git_auth = "be4bef32-d981-489b-bf5c-fc85fe5eff71"

pipeline {
    agent any
    stages {
        stage('拉取代码'){
            steps {
              checkout([$class: 'GitSCM', branches: [[name: '${Branch}']], userRemoteConfigs: [[credentialsId: "${git_auth}", url: "${git_address}"]]])
            }
        }



        stage('构建镜像'){
           steps {
                withCredentials([usernamePassword(credentialsId: "${docker_registry_auth}", passwordVariable: 'password', usernameVariable: 'username')]) {
                sh """
                  echo '
