GCE/GKE Resource Detection

This recipe demonstrates GKE and GCE resource detection in a collector config, deployed with the operator. These resource detectors add the following metadata:

GKE:

* cloud.provider ("gcp")
* cloud.platform ("gcp_gke")
* k8s.cluster.name (name of the GKE cluster)

GCE:

* cloud.platform ("gcp_compute_engine")
* cloud.account.id
* cloud.region
* cloud.availability_zone
* host.id
* host.image.id
* host.type

Prerequisites

• OpenTelemetry Operator installed in your cluster
• Running un-instrumented application (such as one of the sample apps).
• An Instrumentation object already created such as the one from the main README

Running

Apply the OpenTelemetryCollector object from collector-config.yaml:

kubectl apply -f collector-config.yaml

Checking the modified spans

To stream logs from the otel-collector, run:

kubectl logs deployment/otel-collector -f

In these, you should see resource attributes such as the following:

     -> cloud.provider: STRING(gcp)
     -> cloud.platform: STRING(gcp_kubernetes_engine)
     -> cloud.region: STRING(us-central1)
     -> k8s.cluster.name: STRING(autopilot-cluster-1)
