Description:

Summary:

The ObservabilityInstaller CRD allows creation of resources with tracing.enabled: true but without storage configuration, which causes guaranteed reconciliation failures when the controller attempts to create a TempoStack instance.

Steps to Reproduce:

  1. Create an ObservabilityInstaller with minimal configuration:

  apiVersion: observability.openshift.io/v1alpha1
  kind: ObservabilityInstaller
  metadata:
    name: test-minimal
  spec:
    capabilities:
      tracing:
        enabled: true

  2. Apply the resource to the cluster

  3. Check the operator logs

Expected Behavior:

Resource creation should fail with a validation error indicating that storage configuration is required when tracing is enabled.

Actual Behavior:

  - Resource is created successfully

  - Controller reconciliation fails with error: TempoStack.tempo.grafana.com "test-minimal" is invalid:

  spec.storage.secret.type: Unsupported value: "": supported values: "azure", "gcs", "s3"

  - User gets runtime error instead of clear validation failure

Root Cause:{}

The toTempoStorageType() function in tempo_components.go:288 returns an empty string when no storage backend is configured, but TempoStack CRD validation only accepts "azure", "gcs", or "s3".
