OpenTelemetry Operator for Kubernetes

The OpenTelemetry Operator is an implementation of a Kubernetes Operator.

At this point, it has OpenTelemetry Service as the only managed component.

Getting started

To install the operator, run:

kubectl create -f https://raw.githubusercontent.com/jpkrohling/opentelemetry-operator/master/deploy/crds/opentelemetry_v1alpha1_opentelemetryservice_crd.yaml
kubectl create -f https://raw.githubusercontent.com/jpkrohling/opentelemetry-operator/master/deploy/service_account.yaml
kubectl create -f https://raw.githubusercontent.com/jpkrohling/opentelemetry-operator/master/deploy/role.yaml
kubectl create -f https://raw.githubusercontent.com/jpkrohling/opentelemetry-operator/master/deploy/role_binding.yaml
kubectl create -f https://raw.githubusercontent.com/jpkrohling/opentelemetry-operator/master/deploy/operator.yaml

Once the opentelemetry-operator deployment is ready, create an OpenTelemetry Service (otelsvc) instance, like:

kubectl apply -f - <<EOF
apiVersion: opentelemetry.io/v1alpha1
kind: OpenTelemetryService
metadata:
  name: simplest
spec:
  config: |
    receivers:
      jaeger:

    processors:
      queued-retry:

    exporters:
      logging:

    pipelines:
      traces:
        receivers: [jaeger]
        processors: [queued-retry]
        exporters: [logging]

This will create an OpenTelemetry Service instance named simplest, exposing a jaeger-grpc port to consume spans from your instrumented applications and exporting those spans via jaeger-grpc to a remote Jaeger collector.

The config node holds the YAML that should be passed down as-is to the underlying OpenTelemetry Service instances. Refer to the OpenTelemetry Service documentation for a reference of the possible entries.

At this point, the Operator does not validate the contents of the configuration file: if the configuration is invalid, the instance will still be created but the underlying OpenTelemetry Service might crash.
