Dapr state management

In this quickstarts, you'll create a microservice to demonstrate Dapr's state management API. The service generates messages to store data in a state store.

Visit the Dapr documentation on State Management for more information.

Note: This example leverages the Dapr Client SDK. You can find an example using plain HTTP in the http folder.

This quickstart includes one service: Go client service order-processor

Run multiple apps with multi-app run template file

This section shows how to run applications at once using multi-app run template files with dapr run -f .. This enables to you test the interactions between multiple applications.

Open a new terminal window and run order-processor using the multi app run template defined in dapr.yaml:

1. Run the Go service app with Dapr:

  dapr run -f  .

2. Stop and cleanup application process

dapr stop -f .

Run a single app at a time with Dapr (Optional)

An alternative to running all or multiple applications at once is to run single apps one-at-a-time using multiple dapr run .. -- go run commands. This next section covers how to do this.

1. Run the Go service app with Dapr:

cd ./order-processor
dapr run --app-id order-processor --resources-path ../../../resources/ -- go run .

The Terminal console output should look similar to this:

You're up and running! Both Dapr and your app logs will appear here.

    == APP - order-processor == Saved Order: {"orderId":1}
		== APP - order-processor == Retrieved Order: {"orderId":1}
		== APP - order-processor == Deleted Order: {"orderId":1}
		== APP - order-processor == Saved Order: {"orderId":2}
		== APP - order-processor == Retrieved Order: {"orderId":2}
		== APP - order-processor == Deleted Order: {"orderId":2}

2. Stop and clean up application processes dapr stop --app-id order-processor
