Describe your test plan

Play around with the following DatadogAgent configuration:

spec:
  features:
    otlp:
      receiver:
        protocols:
          grpc:
            enabled: true
            hostPortConfig:
              enabled: <true or false>
              hostPort: <host port>
          http:
            enabled: true
            hostPortConfig:
              enabled: <true or false>
              hostPort: <host port>

Run kubectl describe pod <node agent pod> and see if the behavior reflects.

For running the node agent in a single container:

spec:
  global:
    containerStrategy: single
  features:
    otlp:
      receiver:
        protocols:
          grpc:
            enabled: true
            hostPortConfig:
              enabled: <true or false>
              hostPort: <host port>
          http:
            enabled: true
            hostPortConfig:
              enabled: <true or false>
              hostPort: <host port>

Run kubectl describe pod <node agent pod> and see if the behavior reflects.
