默认启动参数/device-bacnet-ip/device-bacnet-c\-cpkeeper://127.0.0.1:59890\--registry\--confdir/res七、配置优先级配置合并顺序高优先级覆盖低优先级C SDK 代码默认值config.c→edgex_common_config_defaultsedgex_private_config_defaults本项目main.c中 Driver 默认值BBMD_ADDRESS、BBMD_PORT、DefaultDevicePathconfiguration.yaml文件环境变量覆盖格式key 中/替换为_全大写。如Service/Host→SERVICE_HOSTClients 专用环境变量CLIENTS_CORE_METADATA_HOST等注册中心配置--registry时configuration.yaml仅作为 fallback八、Docker Host 网络模式最小配置Writable:LogLevel:INFOService:Host:127.0.0.1Port:59980Device:ProfilesDir:./res/profilesDevicesDir:./res/devicesClients:core-metadata:Host:127.0.0.1Port:59881core-command:Host:127.0.0.1Port:59882MessageBus:Type:mqttProtocol:tcpHost:127.0.0.1Port:1883Optional:ClientId:device-bacnetDriver:{}
