pipeline {

    }
    stages {

            steps {
                container('nodejs') {

                    sh 'ls'
                }

            }
        }

        stage('构建镜像') {
            agent none
            steps {
                container('nodejs') {
                    sh 'ls'
                    sh 'docker build -t cyy-admin:latest -f Dockerfile  .'
                }

            }
        }

        stage('推送镜像') {
            agent none
            steps {
                container('nodejs') {
                    withCredentials([usernamePassword(credentialsId : 'aliyun-docker-image' ,usernameVariable : 'DOCKER_USERNAME_VAR' ,passwordVariable : 'DOCKER_PASSWORD_VAR' ,)]) {
                        sh 'echo "$DOCKER_PASSWORD_VAR" | docker login $REGISTRY -u "$DOCKER_USERNAME_VAR" --password-stdin'
                        sh 'docker tag cyy-admin:latest $REGISTRY/$DOCKERHUB_NAMESPACE/cyy-admin:SNAPSHOT-$BUILD_NUMBER'
                        sh 'docker push  $REGISTRY/$DOCKERHUB_NAMESPACE/cyy-admin:SNAPSHOT-$BUILD_NUMBER'
                    }

                }

            }
        }

        // stage('部署到dev环境') {
        //     agent none
        //     steps {
        //         kubernetesDeploy(configs: 'deploy/**', enableConfigSubstitution: true, kubeconfigId: "$KUBECONFIG_CREDENTIAL_ID")
        //     }
        // }

         stage('部署到dev环境') {
              steps {
                  container ('nodejs') {
                       withCredentials([
                           kubeconfigFile(
                           credentialsId: env.KUBECONFIG_CREDENTIAL_ID,
                           variable: 'KUBECONFIG')
                           ]) {
                           sh 'envsubst < deploy/deploy.yml | kubectl apply -f -'
                       }
                  }
              }
         }

        //1、配置全系统的邮件：                   全系统的监控
        //2、修改ks-jenkins的配置，里面的邮件；   流水线发邮件
        stage('发送确认邮件') {
            agent none
            steps {
                mail(to: '[e-mail]', subject: 'cyy-admin构建结果', body: "构建成功了  $BUILD_NUMBER")
            }
        }

    }
    environment {
        DOCKER_CREDENTIAL_ID = 'dockerhub-id'
        GITHUB_CREDENTIAL_ID = 'github-id'
        KUBECONFIG_CREDENTIAL_ID = 'demo-kubeconfig'
        REGISTRY = 'registry.cn-chengdu.aliyuncs.com'
        DOCKERHUB_NAMESPACE = 'ayu-edu'
        GITHUB_ACCOUNT = 'kubesphere'
        APP_NAME = 'devops-java-sample'
    }
}

2、修改请求地址为网关地址

4、修改index.html

• 当初引入富文本的时候使用了变量 BASE_URL 这个变量在HTML-WEBPACK-PLUGIN中需要声明,但是在开发环境使用BASE_URL 打包的时候必须改成 htmlWebpackPlugin.options.url 而且二者只能存在其一 注视也会报错

5、使用git的方式自动生成流水线

部署成功：

    }

        GITHUB_ACCOUNT = 'kubesphere'
        APP_NAME = 'devops-java-sample'
    }
}

2、修改请求地址为后台网关地址

3、修改nuxt监听端口(这个框架默认只监听localhost端口改成0.0.0.0)

4、部署结果

（网关服务active=prod就会调用不到其他服务，不知道什么原因）

5、补充

1、之前springgateway一直读取不到配置中心的配置，后面我尝试更换nacos的版本和项目依赖的nacos版本一致，然后就能读取到配置了，或者重启nacos服务；服务器内存小的朋友不要限制每个服务的内存大小，可能是设置的内存不够，kubesphere提示无法调度的问题，但是不设置内存会把服务器卡死，可以先设置好内存限制，然后出现无法调度的时候手动打开内存限制，但是多了也会卡死。

2、nuxt打包过后，aliyunplayer 引入不成成功，要写在nuxt.config.js里面才行
