Flags

Name Environment Variable Default Description
--app-id, -a APP_ID The id for your application, used for service discovery. Cannot contain dots.
--app-max-concurrency unlimited 应用程序的并发级别；默认为无限制
--app-port, -p APP_PORT 应用程序正在侦听的端口
--app-protocol, -P http Dapr 用于与应用程序通信的协议。 Valid values are: http, grpc, https (HTTP with TLS), grpcs (gRPC with TLS), h2c (HTTP/2 Cleartext)
--resources-path, -d Linux/Mac: $HOME/.dapr/components
Windows: %USERPROFILE%\.dapr\components		 The path for resources directory. If you’ve organized your resources into multiple folders (for example, components in one folder, resiliency policies in another), you can define multiple resource paths. See example below.
--app-channel-address 127.0.0.1 The network address the application listens on
--runtime-path Dapr 运行时安装路径
--config, -c Linux/Mac: $HOME/.dapr/config.yaml
Windows: %USERPROFILE%\.dapr\config.yaml		 Dapr configuration file
--dapr-grpc-port, -G DAPR_GRPC_PORT 50001 The gRPC port for Dapr to listen on
--dapr-internal-grpc-port, -I 50002 The gRPC port for the Dapr internal API to listen on. Set during development for apps experiencing temporary errors with service invocation failures due to mDNS caching, or configuring Dapr sidecars behind firewall. Can be any value greater than 1024 and must be different for each app.
--dapr-http-port, -H DAPR_HTTP_PORT 3500 The HTTP port for Dapr to listen on
--enable-profiling false Enable “pprof” profiling via an HTTP endpoint
--help, -h Print the help message
--run-file, -f Linux/MacOS: $HOME/.dapr/dapr.yaml Run multiple applications at once using a Multi-App Run template file. Currently in alpha and only available in Linux/MacOS
--image Use a custom Docker image. Format is repository/image for Docker Hub, or example.com/repository/image for a custom registry.
--log-level info 日志详细程度。 Valid values are: debug, info, warn, error, fatal, or panic
--enable-api-logging false 启用从应用程序到 Dapr 的所有 API 调用的日志记录
--metrics-port DAPR_METRICS_PORT 9090 Dapr 将 metrics 信息发送到的端口
--profile-port 7777 要监听的性能检测服务的端口
--enable-app-health-check false Enable health checks for the application using the protocol defined with app-protocol
--app-health-check-path Path used for health checks; HTTP only
--app-health-probe-interval 以秒为单位探测应用程序健康状态的间隔
--app-health-probe-timeout 应用健康探测的超时时间（以毫秒为单位）
--app-health-threshold 应用被视为不健康之前的最大连续失败次数
--unix-domain-socket, -u Unix domain socket 目录挂载的路径。 如果指定了，与 Dapr sidecar 的通信将使用 unix domain sockets，与使用 TCP 端口相比，具有更低的延迟和更大的吞吐量。 在 Windows 操作系统上不可用。
--dapr-http-max-request-size 4 请求正文的最大尺寸，单位为MB。
--dapr-http-read-buffer-size 4 Http 请求头读取缓冲区的最大大小，单位为KB。 这也限制了 HTTP 标头的最大大小。 默认是4KB。
--kubernetes, -k Running Dapr on Kubernetes, and used for Multi-App Run template files on Kubernetes.
--components-path, -d Linux/Mac: $HOME/.dapr/components
Windows: %USERPROFILE%\.dapr\components		 Deprecated in favor of --resources-path
