持续集成交付CICD：Jenkins使用GitLab共享库实现前端项目镜像构建

一、实验

1. GitLab修改项目文件与Harbor环境确认

2.Jenkins使用GitLab共享库实现前端项目镜像构建

3.优化CI流水线封装Harbor账户密码

4.Jenkins再次使用GitLab共享库实现前端项目镜像构建

一、实验

1. GitLab修改项目文件与Harbor环境确认

（1）GitLab共享库新建k8sci.jenkinsfile

(2) 查看目录

（3）修改k8sci.jenkinsfile

@Library("mylib@master") _
import org.devops.*def checkout = new Checkout()
def build = new Build()
def unittest = new UnitTest()
def sonar = new Sonar()pipeline {agent { label "build"}options {skipDefaultCheckout true}stages{stage("Checkout"){steps{script {println("GetCode")checkout.GetCode("${env.srcUrl}","${env.branchName}")}}}stage("build"){steps{script{println("Build")build.CodeBuild("${env.buildTool}")}}}stage("UnitTest"){steps{script{println("Test")unittest.CodeTest("${env.buildTool}")}}}stage("SonarScan"){steps {script {groupName = "${JOB_NAME}".split("/")[0]projectName ="${JOB_NAME}".split("/")[-1].split("_")[0]sonar.CodeSonar("${env.buildTool}",projectName,groupName)}}}stage("PushImage"){steps {script {repoName = "${JOB_NAME}".split("/")[0]projectName ="${JOB_NAME}".split("/")[-1].split("_")[0]env.registry = "192.168.204.15"env.imageName = "${env.registry}/${repoName}/${projectName}:${env.branchName}"sh """#重写HTML首页echo "${env.imageName}" > dist/index.html #构建镜像docker build -t ${env.imageName} .#登录镜像仓库docker login -u admin -p Harbor12345 ${env.registry}#上传镜像docker push  ${env.imageName}#删除镜像sleep 2docker rmi ${env.imageName}"""}}}}}

（4）前端项目新增Dockerfile


FROM nginx:1.17.7COPY dist/ /usr/share/nginx/html

（5）Harbor确认devops03项目

2.Jenkins使用GitLab共享库实现前端项目镜像构建

（1）Jenkins新建流水线

（2）取消构建触发器

（3）修改SCM脚本路径

（4）手动构建前端项目流水线

（5）成功

（6）查看Blue Ocean

(7)Harbor已上传前端项目镜像

（8）本地拉取镜像测试

docker pull 192.168.204.15/devops03/devops03-devops-ui:masterdocker run -itd --name devops03demo1 -p 8092:80 192.168.204.15/devops03/devops03-devops-ui:mastercurl http://127.0.0.1:8092

（9）删除容器

docker rm devops03demo1 -f

3.优化CI流水线封装Harbor账户密码

（1）Jenkins新建凭据

（2）生成流水线脚本

（3）Jenkins新建视图

（4）列表添加流水线项目

（5）GitLab共享库修改k8sci.jenkinsfile
