Fixes #1765

This PR adds support for allowNamespaces and denyNamespaces fields in the targetAllocator.prometheusCR configuration for the opentelemetry-kube-stack Helm chart. These fields allow users to control which namespaces should be included or excluded from being scraped by the collector via the Target Allocator.

Changes

  • Added allowNamespaces and denyNamespaces fields to the OpenTelemetryTargetAllocatorPrometheusCR schema in values.schema.json
  • Updated values.yaml to include examples of the new fields

Example Usage

collectors:
  scraper:
    targetAllocator:
      prometheusCR:
        allowNamespaces:
          - namespace-1
          - namespace-2
        denyNamespaces:
          - namespace-3
          - namespace-4

Testing Done

  • Verified schema validation works for the new fields
  • Verified the collector template properly passes through TargetAllocator configuration
