It can be used with kustomize configMapGenerator, here is some examples:

File: mywebapp-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: mywebapp-deployment
spec:
  selector:
    matchLabels:
      app: mywebapp
  replicas: 2
  template:
    metadata:
      labels:
        app: mywebapp
    spec:
      containers:
        - name: mywebapp
          image: nginx:latest
          ports:
            - containerPort: 80
          envFrom:
            - configMapRef:
                name: mywebapp-config

File: kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization

resources:
  - mywebapp-deployment.yaml

commonLabels:
  app: mywebapp

configMapGenerator:
  - name: mywebapp-config
