Tracing

Most of the services contain different jaeger-client libraries to export traces that can be collected using e.g. Jaeger.

Enable tracing in services

By using the default deployment, either using Skaffold or Helm, tracing would be disabled for all services. To enable it, the corresponding environment variables has to be set. This can be done in two ways:

Note: Tracing is configured for Jaeger by default. If you want to use a different service the values have to be adopted.

  1. Using Skaffold with specifying the tracing profile during deployment: 
    skaffold run -p tracing
  2. Using Helm and passing the values file containing the necessary configuration with -f ./chart/tracing.yaml
    See in the Unguard Chart README

    1. Install the Jaeger-Operator 
       helm install jaeger-operator jaegertracing/jaeger-operator --version 2.22.0 --wait --namespace unguard --create-namespace
    2. Deploy the AllInOne image for local development 
       kubectl apply -f ./k8s-manifests/jaeger/jaeger.yaml
  2. For production
    1. Install Jaeger 
      helm install jaeger jaegertracing/jaeger -f ./chart/jaeger.yaml --wait --namespace unguard --create-namespace
