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 none
      steps {
        git(url: '代码地址', credentialsId: 'git-code-auth', branch: 'pro', changelog: true, poll: false)
      }
    }

    stage('构建代码') {
      agent none
      steps {
        container('nodejs') {
          sh '''ls
npm install --force
npm run build:k8sprod'''
        }

      }
    }

    stage('构建镜像') {
      agent none
      steps {
        container('nodejs') {
          sh 'ls'
          sh 'docker build -t tingyuan-cloud-service-web-admin:latest .'
        }

      }
    }

    stage('推送镜像') {
      agent none
      steps {
        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 none
      steps {
        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
