Updating the OpenTelemetry demo application

For this chapter, we have prepared an updated version of OTEL-Collector.yaml, which will add additional labels to metrics for you to explore. Full details on this process are available from the Git repository in the README.md file. This process will apply the new version of the collector configuration to your demo application:

1. Using Helm, we will apply the updated configuration file to our Kubernetes cluster:

   $ helm upgrade --version '0.73.1' --values chapter5/OTEL-Collector.yaml --values OTEL-Creds.yaml owg open-telemetry/opentelemetry-collector
   NAME: owg-otel-collector
   LAST DEPLOYED: Sun Mon 19 12:42:36 2023
   NAMESPACE: default
   STATUS: deployed
   REVISION: 2
   …

2. Validate upgrade was successful:

   $ kubectl get pods --selector=component=standalone-collector
   NAME  READY   STATUS    RESTARTS   AGE
