What happened?

The Ingress object created to expose the Collector outside the cluster is not created properly for the HTTP receiver.

Environment:

• Kind cluster: 1.24
• Ingress controller: v1.0.1

When I create this OpenTelemetry Collector instance:

apiVersion: opentelemetry.io/v1alpha1
kind: OpenTelemetryCollector
metadata:
  name: simplest
spec:
  mode: "deployment"
  ingress:
    type: ingress
  config: |
    receivers:
      otlp:
        protocols:
          grpc:
          http:
    exporters:
      debug:

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

This is the created Ingress instance:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  creationTimestamp: "2023-12-18T11:04:39Z"
  generation: 1
  labels:
    app.kubernetes.io/instance: demo.simplest

        path: /otlp-grpc

              name: otlp-http
        path: /otlp-http
        pathType: Prefix
status:
  loadBalancer: {}

If I run curl to the exposed URL:

$ curl http://localhost/otlp-http/v1/traces
404 page not found

If I try to send traces from a Python application, I can see this error message:

Failed to export batch code: 404, reason: 404 page not found

If I do port forwarding to the 4318 port, and run curl for the same subpath:

$ curl http://localhost:4318/v1/traces
405 method not allowed, supported: [POST]
