我正在尝试在 Mac 中启动 Thingsboard Docker 映像。我正在关注 Mac 中 Docker 的 Thingsboard 安装。我在本地将单节点 cassandra 实例作为 docker 映像运行，并且 cassandra 实例已启动并正在运行。

admin@C02P111XG3QDMBP b2b-order-service (migration) $ cqlsh Connected to Test Cluster at 127.0.0.1:9042. [cqlsh 5.0.1 | Cassandra 3.11.2 | CQL spec 3.4.4 | Native protocol v4] Use HELP for help. cqlsh>

当我启动 Thingsboard Docker 映像时，ThingsBoard 应用程序无法启动，因为它无法连接到 cassandra。以下是 ThingsBoard 的 docker 容器日志。

admin@C02P111XG3QDMBP installation $ docker logs 8f11b6e0605a Selecting previously unselected package thingsboard. (Reading database ... 25169 files and directories currently installed.) Preparing to unpack /thingsboard.deb ... Adding group `thingsboard' (GID 102) ... Done. Unpacking thingsboard (1.4.0-1) ... Setting up thingsboard (1.4.0-1) ... Wait for cassandra db to start...

请帮我解决这个问题，因为这将有助于开始使用 ThingsBoard。

docker-compose.yml 的内容如下所述。

version: '2'

services:
  tb:
    image: "thingsboard/application:1.4.0"
    ports:
      - "8080:8080"
      - "1883:1883"
      - "5683:5683/udp"
    env_file:
      - tb.env
    environment:
      - ADD_SCHEMA_AND_SYSTEM_DATA=${ADD_SCHEMA_AND_SYSTEM_DATA}
      - ADD_DEMO_DATA=${ADD_DEMO_DATA}
    volumes:
      - "${HSQLDB_DATA_DIR}:/usr/share/thingsboard/data/sql"
    entrypoint: /run-application.sh
  cassandra:
    image: "cassandra:3.11.2"
    ports:
      - "9042"
      - "9160"
    volumes:
      - "${CASSANDRA_DATA_DIR}:/var/lib/cassandra"
  zk:
    image: "zookeeper:3.4.10"
    ports:
      - "2181"
    restart: always
  postgres:
    image: "postgres:9.6"
    ports:
    - "5432"
    environment:
      - POSTGRES_DB=${POSTGRES_DB}
    volumes:
      - "${POSTGRES_DATA_DIR}:/var/lib/postgresql/data"

Cassandra 实例在 MAC 主机上运行，​​而 thingsboard 的 docker 容器在同一 MAC 主机上运行。

似乎 Docker 容器无法解析 MAC VM 主机的本地主机。所以我替换了 CASSANDRA_HOST=host.docker.internal 并且它能够连接到在主机 MAC VM 上的 localhost 上运行的 cassandra。
