部署流程

创建DevOps工程

填写流水线信息

创建流水线

1 我们编写JenkinsFile

流水线的部署流程如下图

部署应用所需脚本

jenkinsfile

因为所有服务都写出来实在太长也不方便观看,故以gateway,admin 两个模块为例,增加其他模块也是亦是相同,复制粘贴即可

pipeline {agent {node {label 'jdk11'}}stages {stage('拉取代码') {agent nonesteps {container('maven') {git(url: '你的代码地址', credentialsId: 'git-code-auth', branch: '代码分支', changelog: true, poll: false)sh 'ls'}}}stage('编译代码') {agent nonesteps {container('maven') {sh '''lspwdjava -version'''sh 'mvn clean install -Dmaven.test.skip=true'}}}stage('default-2') {parallel {stage('构建镜像gateway') {agent nonesteps {container('maven') {sh 'ls $GATEWAY/target'sh 'docker build -t $GATEWAY:latest -f $GATEWAY/Dockerfile ./$GATEWAY/'}}}stage('构建镜像tingyuan-cloud-api-admin') {agent nonesteps {container('maven') {sh 'ls $BASE_PATH/$ADMIN/target'sh 'docker build -t $ADMIN:latest -f $BASE_PATH/$ADMIN/Dockerfile ./$BASE_PATH/$ADMIN/'}}}}}stage('default-3') {parallel {stage('推送镜像gateway') {agent nonesteps {container('maven') {withCredentials([usernamePassword(credentialsId: 'aliyun-docker', passwordVariable: 'DOCKER_PASSWORD_VAR', usernameVariable: 'DOCKER_USER_VAR',)]) {sh 'echo "$DOCKER_PASSWORD_VAR" | docker login $REGISTRY -u "$DOCKER_USER_VAR" --password-stdin'sh 'docker tag $GATEWAY:latest $REGISTRY/$DOCKERHUB_NAMESPACE/$GATEWAY:SNAPSHOT-$BUILD_NUMBER'sh 'docker push$REGISTRY/$DOCKERHUB_NAMESPACE/$GATEWAY:SNAPSHOT-$BUILD_NUMBER'}}}}stage('推送镜像admin') {agent nonesteps {container('maven') {withCredentials([usernamePassword(credentialsId: 'aliyun-docker', passwordVariable: 'DOCKER_PASSWORD_VAR', usernameVariable: 'DOCKER_USER_VAR',)]) {sh 'echo "$DOCKER_PASSWORD_VAR" | docker login $REGISTRY -u "$DOCKER_USER_VAR" --password-stdin'sh 'docker tag $ADMIN:latest $REGISTRY/$DOCKERHUB_NAMESPACE/$ADMIN:SNAPSHOT-$BUILD_NUMBER'sh 'docker push$REGISTRY/$DOCKERHUB_NAMESPACE/$ADMIN:SNAPSHOT-$BUILD_NUMBER'}}}}}}stage('default-4') {parallel {stage('deploy gateway to pro') {agent nonesteps {kubernetesDeploy(configs: '文件所在路径/deploy/**', enableConfigSubstitution: true, kubeconfigId: "$KUBECONFIG_CREDENTIAL_ID")}}stage('deploy admin to pro') {agent nonesteps {kubernetesDeploy(configs: '文件所在路径/deploy/**', enableConfigSubstitution: true, kubeconfigId: "$KUBECONFIG_CREDENTIAL_ID")}}}}}environment {DOCKER_CREDENTIAL_ID = 'dockerhub-id'GITHUB_CREDENTIAL_ID = 'github-id'KUBECONFIG_CREDENTIAL_ID = 'demo-kubeconfig'REGISTRY = '镜像仓库地址'DOCKERHUB_NAMESPACE = '镜像创库nameSpace'GITHUB_ACCOUNT = 'kubesphere'BASE_PATH = 'api'GATEWAY = 'gateway'APP = 'app'ADMIN = 'admin'GUILD = 'guild'LANDPAGE = 'landpage'SCHEDULE = 'schedule'WS = 'ws'DB = 'db'SERVICE = 'service'FILE = 'file'}parameters {string(name: 'TAG_NAME', defaultValue: '', description: '')}}

Dockerfile

打包镜像文件
