dapr-apim-integration sample: echo-service and event-subscriber need a tracing config and fail to start

[clarenceb]

echo-service and event-subscriber have the annotation:

dapr.io/config: "tracing"

and fail to start as they can't find this config.

Fix:

• Create a tracing config in file k8s/tracing.config.yaml:

apiVersion: dapr.io/v1alpha1
kind: Configuration
metadata:
  name: tracing
  namespace: default
spec:
  tracing:
    samplingRate: "1"
    zipkin:
      endpointAddress: "http://zipkin.default.svc.cluster.local:9411/api/v2/spans"

kubectl apply -f k8s/tracing.config.yaml

Install Zipkin:

kubectl create deployment zipkin --image openzipkin/zipkin
kubectl expose deployment zipkin --type ClusterIP --port 9411

Redeploy echo-service and event-subscriber.

My environment:

• Dapr 1.5.1
• Kubernetes: v1.21.2
