[bug_fix] Missing resource from OpenShift Routes prevents them to be deployed in OpenShift clusters

[iblancasa]

After #1206 , OpenShift routes are supported by the OpenTelemetry Collector Operator.

In upstream, this works because we're installing the OpenShift Routes CRD in the Kubernetes cluster. But, for OpenShift, the creation of routes don't work.

How to reproduce

When this manifest is deployed:

apiVersion: opentelemetry.io/v1alpha1
kind: OpenTelemetryCollector
metadata:
  name: simplest
spec:
  mode: "deployment"
  ingress:
    type: route
    hostname: "example.com"
    annotations:
      something.com: "true"
    route:
      termination: "insecure"

  config: |
    receivers:
      otlp:
        protocols:
          grpc:

    exporters:
      logging:

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

This error is logged in the OTEL Collector Operator:

{"level":"error","ts":"2022-12-21T16:32:48.213626Z","msg":"Reconciler error","controller":"opentelemetrycollector","controllerGroup":"opentelemetry.io","controllerKind":"OpenTelemetryCollector","OpenTelemetryCollector":{"name":"simplest","namespace":"israel"},"namespace":"israel","name":"simplest","reconcileID":"83890790-0c84-49de-ace1-9c0c305e8d51","error":"failed to reconcile the expected routes: failed to create: Route.route.openshift.io \"otlp-grpc-simplest-route\" is invalid: spec.host: Forbidden: you do not have permission to set the host field of the route","stacktrace":"sigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).reconcileHandler\n\t/go/pkg/mod/sigs.k8s.io/controller-runtime@v0.13.1/pkg/internal/controller/controller.go:326\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).processNextWorkItem\n\t/go/pkg/mod/sigs.k8s.io/controller-runtime@v0.13.1/pkg/internal/controller/controller.go:273\nsigs.k8s.io/controller-runtime/pkg/internal/controller.(*Controller).Start.func2.2\n\t/go/pkg/mod/sigs.k8s.io/controller-runtime@v0.13.1/pkg/internal/controller/controller.go:234"}

And the Collector nor the Route are created.

thanks @iblancasa , but a changelog is missing. Please run chlog-new and fill the created file. [adding a changelog entry]

@iblancasa could you please paste here one links/docs for routes/custom-host resource?

[iblancasa]

@pavolloffay I was not able to find documentation about this in the OpenShift documentation. When I tried to deploy the CR, the pods were not created. This is all the information I was able to collect from the Internet:

• Route's new admission routes/custom-host doesn't work for legacy API openshift/origin#14904
• Red Hat BugZilla - Bug 1524707 - Once a route is given TLS, the TLS section becomes immutable
• OpenShift Documentation for 3.11. Reference to the permission in the table
