内容纲要
| name | default value | 可选值 | 说明 |
|---|---|---|---|
| mode | standalone | standalone / kubernetes | Runtime mode for Dapr |
| dapr-http-port | 3500 | HTTP port for Dapr API to listen on | |
| dapr-grpc-port | 50001 | gRPC port for the Dapr API to listen on | |
| dapr-internal-grpc-port | "" | gRPC port for the Dapr Internal API to listen on 如果不指定，则dapr会自动获取一个随机可用的空闲端口 | |
| app-port | "" | The port the application is listening on 如果不设置，则不能建立dapr和应用之间的 app channel 也就意味着dapr 无法发送请求给应用了 同时dapr也无法从应用读取配置： http://localhost:<app_port>/dapr/config注意：app的地址在代码中写死 127.0.0.1 | |
| profile-port | 7777 | The port for the profile server | |
| app-protocol | http | http / grpc | Protocol for the application: grpc or http |
| components-path | "" | Path for components directory. If empty, components will not be loaded. Self-hosted mode only 仅在dapr mode为standalone时有效 | |
| config | "" | Path to config file, or name of a configuration object 被称为 global configuration 如果是kubernetes mode，读取k8s的配置 如果是standalone mode，读取配置文件 如果没有配置，则装载默认配置 | |
| app-id | "" | A unique ID for Dapr. Used for Service Discovery and state | |
| control-plane-address | "" | Address for a Dapr control plane 仅在dapr mode为kubernetes时有效 | |
| sentry-address | "" | Address for the Sentry CA service | |
| placement-host-address | "" | Address for the Dapr placement service | |
| allowed-origins | * | Allowed HTTP origins | |
| enable-profiling | false | True / false | Enable profiling |
| version | false | True / false | Prints the runtime version （然后dapr就会退出） |
| app-max-concurrency | -1 | Controls the concurrency level when forwarding requests to user code | |
| enable-mtls | false | True / false | Enables automatic mTLS for daprd to daprd communication channels |
1.0 之后被弃用的flag：
| name | 说明 |
|---|---|
| placement-address | 改为 placement-host-address 如果同时设置，以 placement-host-address 为准 |
| max-concurrency | 改为 app-max-concurrency 如果同时设置，以 app-max-concurrency 为准 |
| protocol | 改为 app-protocol 如果同时设置，以 app-protocol 为准 |
