1.前言

前端的打包流程和后端的流程是一样的，只是打包的环境和制作的镜像有所不同，前端需要使用nodejs环境打包，镜像也是使用nginx镜像，因为用的是k8s的pod运行镜像，还需要使用configmap挂载nginx的配置，一套流程还是gitlab+jenkins+harbor+k8s的架构

2.基础环境配置

我们这里就引用之前后端的环境配置，在额外部署一些环境即可

参考：devops(后端)_Apex Predator的博客-CSDN博客

jenkins主机配置

安装nodejs环境

参考：nodejs环境部署_Apex Predator的博客-CSDN博客

gitlab配置

创建前端项目仓库上传代码，我这边是创建了一个nodejs的项目仓库

并且上传了前端的代码，需要做实验的可以到以下连接下载项目代码

项目代码:Release v4.9.2 · Meedu/frontend-v3 · GitHub

harbor配置

创建项目镜像仓库

我这里是创建了一个名为nginx的仓库存放前端的镜像，基础镜像依然是存放在之前创建的base_image仓库中

3.配置项目发布

jenkins配置

创建前端pipeline项目

配置构建流程

这里我们就不配置参数化选择，在执行pipeline的时候让它自动生成，不过这样就会导致在第一次执行的时候会出现报错

构建脚本如下

pipeline {          #该pipeline和后端发布的pipeline并没有太大区别，只是打包命令和项目的参数改变了agent anyenvironment {        #配置环境变量参数registry = "harbor.apex.com"harbor_auth = "a1e2c627-dc62-4599-a035-8e98d74665ab"project = "nginx"app_name = "k8s-qd"namespace = "k8s-qd"k8s_auth = "k8s-kubeconfig"}parameters {         #配置手动执行时选取的ParametergitParameter(branch: '', branchFilter: '.*', defaultValue: '', description: 'Branch for build and deploy', name: 'branch', quickFilterEnabled: false, selectedValue: 'NONE', sortMode: 'NONE', tagFilter: '*', type: 'PT_BRANCH')choice(choices: ['deploy','rollback'], description: '''deploy ---部署  rollback  ---回滚''', name: 'status')}stages {stage ('checkout code') {parallel {stage ('webhook tigger') {when {expression { params.status == 'deploy' && env.gitlabBranch != null }}steps {checkout([$class: 'GitSCM', branches: [[name: '${env.gitlabBranch}']], extensions: [], userRemoteConfigs: [[credentialsId: 'gitlab_auth', url: 'git@10.1.60.114:gitlab-instance-c484dcfc/nodejs.git']]])sh "git branch"echo "Current branch: ${env.gitlabBranch}"script {commit_id = sh(returnStdout: true, script: "git log -n 1 --pretty=format:'%h'").trim()tag = BUILD_TAG + '-' + commit_id}}}stage ('jenkins scm') {when {expression { params.status == 'deploy' && env.gitlabBranch == null }}steps {checkout([$class: 'GitSCM', branches: [[name: '${branch}']], extensions: [], userRemoteConfigs: [[credentialsId: 'gitlab_auth', url: 'git@10.1.60.114:gitlab-instance-c484dcfc/nodejs.git']]])sh "git branch"echo "Current branch: ${branch}"script {commit_id = sh(returnStdout: true, script: "git log -n 1 --pretty=format:'%h'").trim()tag = BUILD_TAG + '-' + commit_id}}}}}stage ('build dist') {when {expression { params.status == 'deploy' }}steps {         #使用nodejs的打包命令编译前端代码sh """npm install --registry=https://registry.npm.taobao.org   #拉取依赖，并指定源npm run build        #编译构建ls dist          #编译后的前端静态文件都在dist目录下"""}}stage ('docker image build and push') {when {expression { params.status == 'deploy' }}steps {withCredentials([usernamePassword(credentialsId: "${harbor_auth}", passwordVariable: 'password', usernameVariable: 'username')]) {sh """docker build -t ${registry}/${project}/${app_name}:${tag} .docker push ${registry}/${project}/${app_name}:${tag}"""}}}stage ('k8s update image version') {parallel {stage ('to master') {when {expression { params.status == 'deploy' && (env.gitlabBranch == 'master' || params.branch == 'master') }}steps {withCredentials([file(credentialsId: "${k8s_auth}", variable: 'KUBECONFIG')]) {sh "kubectl --kubeconfig ${KUBECONFIG} set image deployment ${app_name} ${app_name}=${registry}/${project}/${app_name}:${tag} -n ${namespace} --record"}}}  stage ('to qd_apex') {when {expression { params.status == 'deploy' && (env.gitlabBranch == 'qd_apex' || params.branch == 'qd_apex')}}steps {withCredentials([file(credentialsId: "${k8s_auth}", variable: 'KUBECONFIG')]) {sh "kubectl --kubeconfig ${KUBECONFIG} set image deployment ${app_name} ${app_name}=${registry}/${project}/${app_name}:${tag} -n ${namespace} --record"}}}}}stage ('rollback version') {parallel {stage ('to  master') {when {expression { params.status == 'rollback' && params.branch == 'master' }}steps {withCredentials([file(credentialsId: "${k8s_auth}", variable: 'KUBECONFIG')]) {sh "kubectl --kubeconfig ${KUBECONFIG} rollout undo deployment ${app_name} -n ${namespace}" }}}stage ('to  qd_apex') {when {expression { params.status == 'rollback' && params.branch == 'qd_apex' }}steps {withCredentials([file(credentialsId: "${k8s_auth}", variable: 'KUBECONFIG')]) {sh "kubectl --kubeconfig ${KUBECONFIG} rollout undo deployment ${app_name} -n ${namespace}" }}}}    }}
}

制作基础镜像

vi dockerfile

FROM alpine:latest   #使用alpine系统作为基础镜像
ENV TZ="Asia/Shanghai"    #配置变量
RUN sed -i 's/dl-cdn.alpinelinux.org/repo.huaweicloud.com/g' /etc/apk/repositories \
&& apk add --upgrade --no-cache nginx tzdata ttf-dejavu fontconfig \  #安装nginx和一些软件
&& cp /usr/share/zoneinfo/${TZ} /etc/localtime \
&& echo ${TZ} > /etc/timezone

使用dockefile生成镜像

docker build -t harbor.apex.com/base_image/nginx:latest .

推送镜像到harbor仓库

docker push harbor.apex.com/base_image/nginx:latest

gitlab配置

在创建的前端代码仓库中配置webhook

参考：gitlab配置webhook_Apex Predator的博客-CSDN博客

在项目中新建dockerfile文件用于制作每次前端发版的新版本镜像

dockerfile内容如下

FROM harbor.apex.com/base_image/nginx:latest  #从harbor仓库获取nginx基础镜像
RUN mkdir -p /opt/web    #新建静态文件目录
WORKDIR /opt/web     #设置该目录为工作目录，即相当于cd进入该目录下
COPY ./dist/ ./      #讲编译构建好的静态文件拷贝到该工作目录下
EXPOSE 80           #暴露端口为80
ENTRYPOINT /usr/sbin/nginx -g "daemon off;"   
#启动nginx服务，nginx默认是后台启动的，但是容器是必须要在前台运行服务，不然就视为没有服务在容器中运行，就会导致容器自动关闭，所以使用-g参数使nginx服务在前台运行

k8s集群配置

在master节点上执行

新建命名空间

kubectl create namespace k8s-qd

拷贝nginx配置文件过来，也可以在我这个配置中修改，用于创建configmap服务

vi nginx.conf

#            location = /50x.html {

#    }}

根据以上的nginx配置创建configmap

kubectl create configmap qd-nginx --from-file=/root/nginx.conf -n k8s-qd

kubectl describe configmap qd-nginx -n k8s-qd

可以看到configmap是挂载了nginx配置的

创建secret，用于拉取harbor仓库镜像验证

kubectl create secret docker-registry qd-harbor-secret --namespace=k8s-qd --docker-server=harbor.apex.com --docker-username=admin --docker-password=Harbor12345

新建前端服务的yaml文件

vi k8s-qd.yaml
