Additional node selector getting added in the pods yaml in RHOCP4

Issue

• In the output of oc get pod <podname> -o yaml, there is an additional NodeSelector which is not defined in the pod configuration file.

  • Defined node selector:

  ....
  ....
      template:
        compactor:
          nodeSelector:
           node-role.kubernetes.io/infra: ""
        distributor:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
        gateway:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
        indexGateway:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
        ingester:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
        querier:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
        queryFrontend:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
        ruler:
          nodeSelector:
            node-role.kubernetes.io/infra: ""
  ....
  ....
  

  • Node Selector in the pod's yaml

  $ oc get pod podsname -o yaml
  ....
  ....
    nodeSelector:
      node-role.kubernetes.io/infra: ""
      node-role.kubernetes.io/worker: ""
  ....
