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

pipeline {agent {node {label 'nodejs'}}stages {stage('拉取代码') {agent nonesteps {git(url: '代码地址', credentialsId: 'git-code-auth', branch: 'pro', changelog: true, poll: false)}}stage('构建代码') {agent nonesteps {container('nodejs') {sh '''ls
npm install --force
npm run build:k8sprod'''}}}stage('构建镜像') {agent nonesteps {container('nodejs') {sh 'ls'sh 'docker build -t tingyuan-cloud-service-web-admin:latest .'}}}stage('推送镜像') {agent nonesteps {container('nodejs') {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 镜像仓库地址:SNAPSHOT-$BUILD_NUMBER'sh 'docker push 镜像仓库地址:SNAPSHOT-$BUILD_NUMBER'}}}}stage('发布应用') {agent nonesteps {kubernetesDeploy(configs: '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'GITHUB_ACCOUNT = 'kubesphere'DOCKERHUB_NAMESPACE = '镜像仓库命名空间'}parameters {string(name: 'TAG_NAME', defaultValue: '', description: '')}
}

🌔脚本一些参数如何设置说明

🌏deploy.yaml中的:imagePullSecrets:name属性

imagePullSecrets:- name: aliyun-docker  #提前在项目下配置访问阿里云的账号密码 

选择刚才添加的,添加凭证设置变量

🌏jenkinsfile中的kubeconfigId: “$KUBECONFIG_CREDENTIAL_ID”

🌏jenkinsfile中的git-code-auth属性
