Orion 上下文代理不会“动态”创建租户数据库

Question

我在 docker 容器中创建并运行 fiware-iot-agent 以及 fiware-orion 上下文代理。我使用的 mongoDb 是一个具有 2 个分片且启用了身份验证的分片集群。我验证了 orion 正在连接到集群。 下面是我使用的 docker-compose.yml。

version: "3.8"
services:
  # Orion is the context broker
  orion:
    image: fiware/orion:${ORION_VERSION}
    hostname: orion
    container_name: fiware-orion-pms

    expose:
      - "${ORION_PORT}"
    ports:

    command: -dbhost 192.168.2.5:27030 -dbuser $DB_USER -dbpwd $DB_PWD -dbAuthDb admin  -db orion -logLevel DEBUG
    healthcheck:
      test: curl --fail -s http://orion:${ORION_PORT}/version || exit 1
      interval: 5s

我的问题是，当我使用端点

http://localhost:4041/iot/devices

将新设备添加到固件时，它会创建一个名为 iotagentul 的数据库，并在其中创建一个名为 devices 的集合。我添加的设备正在保存到该集合中。到目前为止，一切都很好。但我希望在添加新设备时创建另一个数据库。在 Orion 文档中这样说：

通常，Orion Context Broker 仅使用 MongoDB 级别的一个数据库（使用 -db 命令行选项指定的数据库，通常为“orion”）。但是，当使用多租户/多服务时，行为会有所不同，并且使用以下数据库（设为 -db 命令行选项的值）： 默认租户的数据库（通常为 orion） 数据库 - 用于服务/租户（例如，如果租户名为tenantA并且使用默认的-db，则数据库将为orion-tenantA。当涉及租户数据的第一个请求由Orion处理时，每个服务/租户数据库是“动态”创建的。 最后，对于每个服务/租户数据库，所有集合和管理过程（备份、恢复等）都与每个特定服务/租户数据库相关联。

因此，根据此，应该有其他数据库来保存设备的实体。但他们没有出现。我未经授权尝试使用 mongo 但它仍然是一样的。我怎么解决这个问题？如有任何帮助，我们将不胜感激。

编辑：我的请求正文如下所示：

    {
 "devices": [
   {
     "device_id": "PA_TALASLI1",
     "entity_name": "PA_TALASLI1",
     "entity_type": "power_analysis",
     "transport":   "HTTP",
     "timezone":    "Europe/Istanbul",
     "attributes": [
       { "object_id": "Voltage_UL1_N", "name":"Voltage_UL1_N", "type":"Double"},
       { "object_id": "Voltage_UL2_N", "name":"Voltage_UL2_N", "type":"Double"},
       { "object_id": "Voltage_UL3_N", "name":"Voltage_UL3_N", "type":"Double"},
       { "object_id": "Current_L1", "name":"Current_L1", "type":"Double"},
       { "object_id": "Current_L2", "name":"Current_L2", "type":"Double"},
       { "object_id": "Current_L3", "name":"Current_L3", "type":"Double"},
       { "object_id": "Total_Active_Power", "name":"Total_Active_Power", "type":"Double"},
       { "object_id": "Total_Reactive_Power", "name":"Total_Reactive_Power", "type":"Double"},
       { "object_id": "Total_Power_Factor", "name":"Total_Power_Factor", "type":"Double"},
       { "object_id": "Total_Active_Energy_IN_T1", "name":"Total_Active_Energy_IN_T1", "type":"Double"},
       { "object_id": "Total_Active_Energy_IN_T2", "name":"Total_Active_Energy_IN_T2", "type":"Double"},
       { "object_id": "Total_Active_Energy_EX_T1", "name":"Total_Active_Energy_EX_T1", "type":"Double"},
       { "object_id": "Total_Active_Energy_EX_T2", "name":"Total_Active_Energy_EX_T2", "type":"Double"}
      ],
      "lazy":[
        { "object_id": "Voltage_UL1_N", "name":"Voltage_UL1_N", "type":"Double"}
      ],
      "static_attributes": [
         {"name":"refStore", "type": "Relationship","value": "urn:ngsi-ld:pa_talasli1:001"}
      ]
   }
 ]
}

我尝试使用日志级别调试运行容器，但没有看到任何有关实体创建的信息。如果我向主体添加一个

lazy 属性，它会创建一个名为 registerations 的表，但没有实体表。我专门通过 /v2/entities/

 创建了一个实体，但我需要的是在将新设备添加到 

/iot/devices 后创建实体

Orion 默认不使用租户。您必须通过使用 CLI 参数

-multiservice

 来告诉它（至少前一段时间它是这样工作的）。
