Feedback

If I configure alloy.extraPorts according to the documentation as follows:

alloy:
  extraPorts:
    - targetPort: 4317
      hostPort: 4317
      name: otlp-grpc

I get this error from kubernetes after helm upgrade:

Error: UPGRADE FAILED: cannot patch "alloy" with kind Service: Service "alloy" is invalid: spec.ports[1].port: Invalid value: 0: must be between 1 and 65535, inclusive

This is because the generated manifest looks like this:

...
    ports:
      - name: http-metrics
         port: 12345
         targetPort: 12345
         protocol: "TCP"
      - name: otlp-grpc
        port: 
        targetPort: 4317
        protocol: TCP
.... 

So I changed configuration to the following:

alloy:
  extraPorts:
    - targetPort: 4317
      port: 4317
      name: otlp-grpc

...and it worked well!

This should be reflected to the documentation.
