学习尚硅谷老师的课程，在此记录一下，感谢尚硅谷老师！！！

1. 创建
   

2. 基本信息的配置后，点击下一步，点击创建
   

3. 配置流水线， 点击取消
   

4. 点击 编辑 jenkinsfile , 开始配置流水线
   

5. Jenkinsfile 文件方式， Jenkinsfile文件为：

pipeline {
  agent {
    node {
      label 'maven'
    }

  }
  stages {
    stage('拉取代码') {
      steps {
        git(url: 'https://gitee.com/qinenqi/gulimall.git', credentialsId: 'gitee-id', branch: 'master', changelog: true, poll: false)
        sh 'echo 正在构建 $PROJECT_NAME  版本号：$PROJECT_VERSION 将会提交给 $REGISTRY 镜像仓库'
        container('maven') {
          sh 'mvn clean install -Dmaven.test.skip=true -gs `pwd`/mvn-settings.xml'
        }

      }
    }


    stage('构建镜像-推送镜像') {
      steps {
        container('maven') {
          sh 'mvn -Dmaven.test.skip=true -gs `pwd`/mvn-settings.xml clean package'
          sh 'cd $PROJECT_NAME && docker build -f Dockerfile -t $REGISTRY/$DOCKERHUB_NAMESPACE/$PROJECT_NAME:SNAPSHOT-$BRANCH_NAME-$BUILD_NUMBER .'
          withCredentials([usernamePassword(passwordVariable : 'DOCKER_PASSWORD' ,usernameVariable : 'DOCKER_USERNAME' ,credentialsId : "$DOCKER_CREDENTIAL_ID" ,)]) {
            sh 'echo "$DOCKER_PASSWORD" | docker login $REGISTRY -u "$DOCKER_USERNAME" --password-stdin'
            sh 'docker tag  $REGISTRY/$DOCKERHUB_NAMESPACE/$PROJECT_NAME:SNAPSHOT-$BRANCH_NAME-$BUILD_NUMBER $REGISTRY/$DOCKERHUB_NAMESPACE/$PROJECT_NAME:latest '
            sh 'docker push  $REGISTRY/$DOCKERHUB_NAMESPACE/$PROJECT_NAME:latest '
          }

        }

      }
    }


    stage('部署到k8s') {
      steps {
        input(id: "deploy-to-dev-$PROJECT_NAME", message: "是否将 $PROJECT_NAME 部署到集群中?")
        kubernetesDeploy(configs: "$PROJECT_NAME/deploy/**", enableConfigSubstitution: true, kubeconfigId: "$KUBECONFIG_CREDENTIAL_ID")
      }
    }
    stage('发布版本'){

      steps {
          container ('maven') {
            input(id: 'release-image-with-tag', message: '发布当前版本镜像吗?')
            sh 'docker tag  $REGISTRY/$DOCKERHUB_NAMESPACE/$PROJECT_NAME:SNAPSHOT-$BRANCH_NAME-$BUILD_NUMBER $REGISTRY/$DOCKERHUB_NAMESPACE/$PROJECT_NAME:$PROJECT_VERSION '
            sh 'docker push  $REGISTRY/$DOCKERHUB_NAMESPACE/$PROJECT_NAME:$PROJECT_VERSION '
            withCredentials([usernamePassword(credentialsId: "$GITEE_CREDENTIAL_ID", passwordVariable: 'GIT_PASSWORD', usernameVariable: 'GIT_USERNAME')]) {
                sh 'git config --global user.email "534096094@qq.com" '
                sh 'git config --global user.name "leifengyang" '
                sh 'git tag -a $PROJECT_NAME-$PROJECT_VERSION -m "$PROJECT_VERSION" '
                sh 'git push http://$GIT_USERNAME:$GIT_PASSWORD@gitee.com/$GITEE_ACCOUNT/gulimall.git --tags --ipv4'
            }

        }
      }
    }

  }

    environment {
      DOCKER_CREDENTIAL_ID = 'dockerhub-id'
      GITEE_CREDENTIAL_ID = 'gitee-id'
      KUBECONFIG_CREDENTIAL_ID = 'demo-kubeconfig'
      REGISTRY = 'docker.io'
      DOCKERHUB_NAMESPACE = 'qinenqi'
      GITEE_ACCOUNT = 'qinenqi'
      SONAR_CREDENTIAL_ID = 'sonar-qube'
      BRANCH_NAME = 'master'
    }
  parameters {
    string(name: 'PROJECT_VERSION', defaultValue: 'v0.0Beta', description: '项目版本')
    string(name: 'PROJECT_NAME', defaultValue: 'gulimall-gateway', description: '构建模块')
  }
}

6. 点击确定

7. 开始运行流水线，打包 gulimall-gateway 项目，进行测试


点击确定
等待大约十来分钟，部署完成

https://hub.docker.com/ 项目也推送了

服务也已经部署到了k8s中了

8. 测试服务是否可用

测试成功

1. 执行流水线，服务没有被替换，原因是 imagePullPolicy: IfNotPresent 这个配置项，替换为：imagePullPolicy: Always 即可
