Service Invocation

In this quickstart, you'll create a checkout service and an order-processor service to demonstrate how to use the service invocation API. The checkout service uses Dapr's HTTP proxying capability to invoke a method on the order processing service.

Check out the documentation about service invocation for more details.

This quickstart includes one checkout service: Go client service checkout

And one order processor service: Go order-processor service order-processor

Run Go order-processor with Dapr

1. Run the order-processor app with Dapr in the order-processor folder:

cd ./order-processor
dapr run \
  --app-port 6001 \
  --app-id order-processor \
  --app-protocol http \
  --dapr-http-port 3501 \
  -- go run .

Run Go checkout with Dapr

1. Open a new terminal window and navigate to checkout directory, then run the Go checkout app with Dapr:

cd ./checkout
dapr run \
  --app-id checkout \
  --dapr-http-port 3500 \
  -- go run .

To stop:

dapr stop --app-id checkout
dapr stop --app-id order-processor

Start all apps with multi app run template file:

1. Run the multi app run template:

sleep 10
dapr run -f .

dapr stop -f .
