dapr run [flags] [command]

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 The concurrency level of the application; default is unlimited
--app-port, -p APP_PORT The port your application is listening on
--app-protocol, -P http The protocol Dapr uses to talk to the application. 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 runtime install path
--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 The log verbosity. Valid values are: debug, info, warn, error, fatal, or panic
--enable-api-logging false Enable the logging of all API calls from application to Dapr
--metrics-port DAPR_METRICS_PORT 9090 The port that Dapr sends its metrics information to
--profile-port 7777 The port for the profile server to listen on
--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 Interval to probe for the health of the app in seconds
--app-health-probe-timeout Timeout for app health probes in milliseconds
--app-health-threshold Number of consecutive failures for the app to be considered unhealthy
--unix-domain-socket, -u Path to a unix domain socket dir mount. If specified, communication with the Dapr sidecar uses unix domain sockets for lower latency and greater throughput when compared to using TCP ports. Not available on Windows.
--dapr-http-max-request-size 4 Max size of the request body in MB.
--dapr-http-read-buffer-size 4 Max size of the HTTP read buffer in KB. This also limits the maximum size of HTTP headers. The default 4 KB
--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

Examples

# Run a .NET application
dapr run --app-id myapp --app-port 5000 -- dotnet run

# Run a .Net application with unix domain sockets
dapr run --app-id myapp --app-port 5000 --unix-domain-socket /tmp -- dotnet run

# Run a Java application
dapr run --app-id myapp -- java -jar myapp.jar

# Run a NodeJs application that listens to port 3000
dapr run --app-id myapp --app-port 3000 -- node myapp.js

# Run a Python application
dapr run --app-id myapp -- python myapp.py

# Run sidecar only
dapr run --app-id myapp

# Run a gRPC application written in Go (listening on port 3000)
dapr run --app-id myapp --app-port 5000 --app-protocol grpc -- go run main.go

# Run a NodeJs application that listens to port 3000 with API logging enabled
dapr run --app-id myapp --app-port 3000 --enable-api-logging  -- node myapp.js

# Pass multiple resource paths
dapr run --app-id myapp --resources-path path1 --resources-path path2

# Run the multi-app run template file
dapr run -f dapr.yaml

# Run the multi-app run template file on Kubernetes
dapr run -k -f dapr.yaml
