如何启用数据集成功能

数据集成是 HAP 系统中的扩展模块，用户可自主选择是否启用，启用之前请确保 Docker 版本在 20.10.16 及以上，服务器空余物理内存 8G+。

单机部署模式快速安装可参考如下：（集群部署模式下相对复杂，可联系 HAP 团队协助完成）

1. 下载镜像（离线包下载）

   docker pull registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-flink:1.17.1.530

2. 修改 docker-compose.yaml（默认路径为：/data/mingdao/script/docker-compose.yaml），主要涉及2部分调整

   1. 添加 flink 服务

      flink:
        image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-flink:1.17.1.530
        entrypoint: ["/bin/bash"]
        command: ["/run.sh"]
        volumes:
          - ./volume/data/:/data/

      注意：如果 docker logs $(docker ps | grep '\-sc' | awk '{print $1}') | grep minio 有输出结果，则需要在 flink 服务增加 ENV_FLINK_S3_ENDPOINT 环境变量

      flink:
        image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-flink:1.17.1.530
        entrypoint: ["/bin/bash"]
        command: ["/run.sh"]
        environment: 
          ENV_FLINK_S3_ENDPOINT: "sc:9010"
        volumes:
          - ./volume/data/:/data/

   2. app 服务添加 ENV_FLINK_URL 环境变量

      app:
        environment:
          ENV_FLINK_URL: "http://flink:8081"
      示例

      version: '3'
      
      services:
        app:
          image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-community:5.4.0
          environment: &app-environment
            ENV_ADDRESS_MAIN: "https://hap.domain.com"
            ENV_APP_VERSION: "5.4.0"
            ENV_API_TOKEN: "******"
            ENV_FLINK_URL: "http://flink:8081" #新增
          ports:
            - 8880:8880
          volumes:
            - ./volume/data/:/data/
            - ../data:/data/mingdao/data
      
        sc:
          image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-sc:2.0.1
          environment:
            <<: *app-environment
          volumes:
            - ./volume/data/:/data/
      
        command:
          image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-command:node1018-python36
          environment:
            <<: *app-environment
      
        doc:
          image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-doc:1.2.0
          environment:
            ENV_FILE_INNER_URI: "app:8880"
      
        # 新增
        flink:
          image: registry.cn-hangzhou.aliyuncs.com/mdpublic/mingdaoyun-flink:1.17.1.530
          entrypoint: ["/bin/bash"]
          command: ["/run.sh"]
          environment: 
            ENV_FLINK_S3_ENDPOINT: "sc:9010"
          volumes:
            - ./volume/data/:/data/
