opentelemetry-operator.v0.103.0-27-gd58cf10b
Description of the problem:
When an endpoint and port is specified in the OTEL collector receiver config, invalid target port is used in the collector service.
receivers: otlp/blue: protocols: http: otlp/green: protocols: http: endpoint: 0.0.0.0:4319 oc get svc otlp-forward-connector-collector -o yaml ports: - appProtocol: http name: otlp-blue-http port: 4318 protocol: TCP targetPort: 4318 - appProtocol: http name: otlp-green-http port: 4319 protocol: TCP targetPort: 4318 -- Port should be 4319
Steps to reproduce the issue:
1. Install the OTEL operator built off the latest upstream branch.
2. Create the OTEL collector instance using following CR:
apiVersion: opentelemetry.io/v1alpha1 kind: OpenTelemetryCollector metadata: name: otlp-forward-connector spec: mode: deployment image: ghcr.io/open-telemetry/opentelemetry-collector-releases/opentelemetry-collector-contrib:0.103.1 config: | receivers: otlp/blue: protocols: http: otlp/green: protocols: http: endpoint: 0.0.0.0:4319 processors: attributes/blue: actions: - key: otel_pipeline_tag value: "blue" action: insert attributes/green: actions: - key: otel_pipeline_tag value: "green" action: insert batch: exporters: debug: verbosity: detailed connectors: forward: service: pipelines: traces/blue: receivers: [otlp/blue] processors: [attributes/blue] exporters: [forward] traces/green: receivers: [otlp/green] processors: [attributes/green] exporters: [forward] traces: receivers: [forward] processors: [batch] exporters: [debug]
3. Check the service created for the collector instance. The target port for otlp-green-http must be 4319
