How can I stop flux from deploying to my default namespace?

Question

I have a Kubernetes cluster setup with Flux. I have an infrastructure folder that has ingress/base and ingress/overlays/development in it. Hopefully this screenshot helps with the directory structure:

Below are my ingress.yaml and kustomization.yaml files from base:

# ingress.yaml
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: my-ingress
  annotations:
    kubernetes.io/ingress.class: alb
    alb.ingress.kubernetes.io/scheme: internet-facing
    alb.ingress.kubernetes.io/target-type: ip
spec:
  rules:
    - http:
        paths:
          - path: /*
            backend:
              serviceName: user-service
              servicePort: 80

# kustomization.yaml
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
  - ingress.yaml

In development's folder I have just a kustomization file:

# kustomization.yaml
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
namespace: development
resources:
  - ../../base

When I commit this structure to my flux repository everything successfully reconciles. However, its setting up an ingress in the default and development namespaces. I want the base folder to be the common config applied to every namespace, I don't want it deployed on its own.

How can I tell Kustomize, or flux, to only use my base folders as inputs to the overlays instead of actually deploying the base folder?

You should use spec.path in your Flux Kustomization component.

spec:
  path: "./infrastructure/overlays"
