OpenTelemetry Operator for Kubernetes (original) (raw)

An implementation of a Kubernetes Operator, that manages collectors and auto-instrumentation of the workload using OpenTelemetry instrumentation libraries.

Introduction

TheOpenTelemetry Operatoris an implementation of aKubernetes Operator.

The operator manages:

• OpenTelemetry Collector
• auto-instrumentation of the workloads using OpenTelemetry instrumentation libraries

Getting started

To install the operator in an existing cluster, make sure you havecert-manager installed and run:

kubectl apply -f https://github.com/open-telemetry/opentelemetry-operator/releases/latest/download/opentelemetry-operator.yaml

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

$ kubectl apply -f - <<EOF
apiVersion: opentelemetry.io/v1beta1
kind: OpenTelemetryCollector
metadata:
  name: simplest
spec:
  config:
    receivers:
      otlp:
        protocols:
          grpc:
            endpoint: 0.0.0.0:4317
          http:
            endpoint: 0.0.0.0:4318
    processors:
      memory_limiter:
        check_interval: 1s
        limit_percentage: 75
        spike_limit_percentage: 15

    exporters:
      # NOTE: Prior to v0.86.0 use `logging` instead of `debug`.
      debug: {}

    service:
      pipelines:
        traces:
          receivers: [otlp]
          processors: [memory_limiter]
          exporters: [debug]
EOF
