Run

To run this demo in Dapr, run:

dapr run \
    --app-id http-service-demo \
    --app-port 8080 \
    --app-protocol http \
    --dapr-http-port 3500 \
    --components-path ./config \
    go run main.go

Deploy

Deploy and wait for the pod to be ready

kubectl apply -f deployment.yaml
kubectl rollout status deployment/http-echo-service

If you have changed an existing component, make sure to reload the ingress and wait until the new version is ready

kubectl rollout restart deployment/nginx-ingress-nginx-controller
kubectl rollout status deployment/nginx-ingress-nginx-controller

Follow logs

kubectl logs -l app=http-echo-service -c service -f

In a separate terminal session export API token

export API_TOKEN=$(kubectl get secret dapr-api-token -o jsonpath="{.data.token}" | base64 --decode)

And invoke the service

curl -d '{ "message": "ping" }' \
     -H "Content-type: application/json" \
     -H "dapr-api-token: ${API_TOKEN}" \
     "https://api.cloudylabs.dev/v1.0/invoke/http-echo-service/method/echo"

The response should include the sent message

{ 
    "message": "ping" 
}

And the logs

Invocation (ContentType:application/json, Verb:POST, QueryString:map[], Data:{ "message": "ping" })
