Describe the issue you're reporting

Hi,

I'm trying to run the targetAllocator in namespace mode, but I encountered the following errors:

Config

  targetAllocator:
    allocationStrategy: consistent-hashing
    enabled: true
    filterStrategy: relabel-config
    observability:
      metrics: {}
    podSecurityContext:
      fsGroup: 1000700000
      seccompProfile:
        type: RuntimeDefault
    prometheusCR:
      enabled: true
      podMonitorSelector: {}
      scrapeInterval: 30s
      serviceMonitorSelector: {}

The collector is configured to run with a serviceAccount bound to a Role, limiting access to a namespace only.

the target allocator already has a servicemonitor and podmonitor namespace selectro, we just need to expose it in the operator here.

Hi @jaronoff97 I'd love to know if this is still being worked on?

jaronoff97 commented 1 month ago

@RichardChukwu I don't believe so... cc @alita1991 are you still interested in working on this?
