How to Enable Data Integration Feature

tip
  • Data integration is an optional extension module of the HAP system, and users can decide whether to enable it based on actual needs.
  • Before enabling, please ensure Docker version is 20.10.16 or above, and the server has at least 8GB of available physical memory.
  • If the server deploying HAP has 32GB, please do not enable this module additionally, as it will worsen the memory shortage, affecting system availability. It is recommended to upgrade to 64GB before enabling.

For quick installation in standalone deployment mode, refer to the following: (cluster deployment mode is relatively complex and HAP team assistance is recommended)

  1. Download the image (Offline package download)

    docker pull nocoly/hap-flink:1.17.1.530

  2. Execute the following command to check if there is an output containing the keyword start minio in one line of content

    docker logs $(docker ps | grep hap-sc | awk '{print $1}') | grep minio

    1. Modify the docker-compose.yaml file (default path: /data/hap/script/docker-compose.yaml)

      1. Add flink service

          flink:
            image: nocoly/hap-flink:1.17.1.530
            entrypoint: ["/bin/bash"]
            command: ["/run.sh"]
            environment: 
              ENV_FLINK_S3_ENDPOINT: "sc:9010"
            volumes:
              - ./volume/data/:/data/

      2. Add the ENV_FLINK_URL environment variable to the app service

        app:
          environment:
            ENV_FLINK_URL: "http://flink:8081"
        Example
        version: '3'

        services:
          app:
            image: nocoly/hap-community:6.3.3
            environment: &app-environment
              ENV_ADDRESS_MAIN: "https://hap.domain.com"
              ENV_APP_VERSION: "6.3.3"
              ENV_API_TOKEN: "******"
              ENV_FLINK_URL: "http://flink:8081" #added content
            ports:
              - 8880:8880
            volumes:
              - ./volume/data/:/data/
              - ../data:/data/hap/data

          sc:
            image: nocoly/hap-sc:3.1.0
            environment:
              <<: *app-environment
            volumes:
              - ./volume/data/:/data/

          command:
            image: nocoly/hap-command:node2011-python312
            environment:
              <<: *app-environment

          doc:
            image: nocoly/hap-doc:2.0.0
            environment:
              ENV_FILE_INNER_URI: "app:8880"

          # following content is added
          flink:
            image: nocoly/hap-flink:1.17.1.530
            entrypoint: ["/bin/bash"]
            command: ["/run.sh"]
            environment: 
              ENV_FLINK_S3_ENDPOINT: "sc:9010"
            volumes:
              - ./volume/data/:/data/

    2. Restart HAP service
