I have 2 kustomization overlays that call the same configuration. I need to have two kustomization.yaml files in the same folder

overlays -----> configuration1 ----> kustomization.yaml 
         |   
         |----> configuration2 ----> kustomization.yaml



resources ------> kustomization.yaml

# in file resources/kustomization.yaml
# for configuration1 
resources:
  - pvc.yaml
  - deployment.yaml
  - namespace.yaml

# for configuration2
resources:
  - pvc.yaml
  - network.yaml
  - istio.yaml

end goal

kubectl apply -k overlays/configuration1
kubectl apply -k overlays/configuration2

I have an overlays folder that contains two folders. configuration1 and configuration2. In those folders I have a kustomization.yaml file. These two kustomization files call the same resource folder. configuration1 and configuration2 need to have a different list of resources specified. Can I create two different kustomize.yaml files in the resource folder or is there anyway to specify two different list of resources in the same kustomization.yaml?

kubectl kustomize kubernetes

In this case it would use the following structure:

base/
  kustomization.yaml
  pvc.yaml
overlays/
  configuration1/
    kustomization.yaml
    deployment.yaml
    namespace.yaml
  configuration2/
    kustomization.yaml
    network.yaml
    istio.yaml

base/kustomization.yaml:

resources:
  - pvc.yaml

overlays/configuration1/kustomization.yaml:

resources:
  - ../../base
  - namespace.yaml
  - deployment.yaml

overlays/configuration2/kustomization.yaml:

resources:
  - ../../base
  - network.yaml
  - istio.yaml

The idea is to keep in the base the configuration that is common to both and move to each overlay the configuration specific to it.
