STEP2: With Kustomize


1. create folder call "accounts" under defaultapps.

inside accounts,
kustomization.yaml

"

	apiVersion: kustomize.config.k8s.io/v1beta1
	kind: Kustomization
	namespace: default
	resources:
	- deploy.yaml

"

deploy.yaml (same above deploy yml content without namespace line)

2. create below kustomization.yaml file under defaultapps.

apiVersion: kustomize.config.k8s.io/v1beta1
	kind: Kustomization
	namespace: default
	resources:
	- ./accounts YOU WILL SEE NGINX PODS ..
