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
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
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
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:

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

如果同时设置,以 app-protocol 为准
