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gitlabjenkinsharbork8s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.comharbor_auth a1e2c627-dc62-4599-a035-8e98d74665abproject nginxapp_name k8s-qdnamespace k8s-qdk8s_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: git10.1.60.114:gitlab-instance-c484dcfc/nodejs.git]]])sh git branchecho Current branch: ${env.gitlabBranch}script {commit_id sh(returnStdout: true, script: git log -n 1 --prettyformat:%h).trim()tag BUILD_TAG - commit_id}}}stage (jenkins scm) {when {expression { params.status deploy env.gitlabBranch null }}steps {checkout([$class: GitSCM, branches: [[name: ${branch}]], extensions: [], userRemoteConfigs: [[credentialsId: gitlab_auth, url: git10.1.60.114:gitlab-instance-c484dcfc/nodejs.git]]])sh git branchecho Current branch: ${branch}script {commit_id sh(returnStdout: true, script: git log -n 1 --prettyformat:%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 --registryhttps://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 ${namespace} }}}} }}
} 制作基础镜像
vi dockerfile
FROM alpine:latest #使用alpine系统作为基础镜像
ENV TZAsia/Shanghai #配置变量
RUN sed -i s/dl-cdn.alpinelinux.org/repo.huaweicloud.com/g /etc/apk/repositories \apk add --upgrade --no-cache nginx tzdata ttf-dejavu fontconfig \ #安装nginx和一些软件cp /usr/share/zoneinfo/${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

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 --namespacek8s-qd --docker-serverharbor.apex.com --docker-usernameadmin --docker-passwordHarbor12345 新建前端服务的yaml文件

启动该yaml服务
kubectl apply -f k8s-qd.yaml 4.发布展示
手动构建 可以看到手动构建的时候git parameter选框会自动去拉取gitlab项目中的所有分支默认是没有选择的需要手动选择status是默认选择deploy为发布 也可以看到第一次构建是失败的这是因为没有手动配置parameter的原因在第一次执行时会根据pipeline脚本中的配置自动生成parameter 再次进入配置也可以看到配置构建流程的时候是没有配置这些参数的这些都配置在pipeline脚本中第一次构建的时候会自动生成但是相应的第一次构建也会执行失败
自动化构建
我在gitlab配置了过滤只有推分支合并master的时候才触发构建现在来合并一下master触发构建 点击批准合并后查看jenkins是否触发构建 可以看到通过自动触发的构建也是成功完成了发布的
也可以通过blue ocean功能更直观的看到构建流程blue ocean需要安装插件 至此配置完成
