apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
	  annotations: 
        k8s.ctyun.cn/eci-use-specs: s7.xlarge.2 # 指定ECS规格
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: registry-huadong1.crs-internal.ctyun.cn/open-source/nginx:1.25-alpine
        ports:
        - containerPort: 80
      nodeName: vnd-u53cymkxxxx-cn-huadong1-jsnj1a-public-ctcloud
