如何使用模板生成器生成kubernetes部署yaml文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .DeploymentName }}
  labels:
    app: {{ .AppName }}
spec:
  replicas: {{ .Replicas }}
  selector:
    matchLabels:
      app: {{ .AppName }}
  template:
    metadata:
      labels:
        app: {{ .AppName }}
    spec:
      containers:
      - name: {{ .ContainerName }}
        image: {{ .Image }}
        ports:
        - containerPort: {{ .Port }}

kubectl create deployment my-deployment \
  --image=my-image \
  --dry-run=client \
  -o yaml > deployment.yaml

kubectl apply -f deployment.yaml.template \
  --namespace=default \
  --record \
  -o yaml > deployment.yaml

kubectl apply -f deployment.yaml.template \
  --namespace=default \
  --record \
  -o yaml \
  --overrides='
    {
      "DeploymentName": "my-deployment",
      "AppName": "my-app",
      "Replicas": 3,
      "ContainerName": "my-container",
      "Image": "my-image:latest",
      "Port": 80
    }
  ' > deployment.yaml
