GCP 副本数中的 Kubernetes GKE 不匹配

Question

我有以下 yaml 文件，副本集为 3，但是当我在 yaml 和控制台中将它部署到 GKE 上时，副本数只有一个。当我部署时， pods 被创建但随后被终止。我忘记了什么？

apiVersion: apps/v1
kind: Deployment
metadata:
  name: xxx-nginx
  namespace: xxx
  labels:
    app: xxx-nginx
spec:
  replicas: 3
  selector:
    matchLabels:
      app: xxx-nginx
  template:
    metadata:
      labels:
        app: xxx-nginx
    spec:
      volumes:
      - name: xxx-nginx
        configMap:
          name: xxx-nginx-configmap
      containers:
      - name: xxx-nginx
        image: nginx:1.15.3
        imagePullPolicy: Always
        ports:
        - containerPort: 80
        volumeMounts:
        - mountPath: /etc/nginx/conf.d
          name: xxx-nginx
        readinessProbe:
          httpGet:
            path: /nginx-health
            port: 80
          initialDelaySeconds: 15
          timeoutSeconds: 1
          periodSeconds: 10
        livenessProbe:
          httpGet:
            path: /nginx-health
            port: 80
          initialDelaySeconds: 15
          timeoutSeconds: 1
          periodSeconds: 10
        resources:
          requests:
            memory: 128Mi
            cpu: 100m
          limits:
            memory: 128Mi
            cpu: 100m

这是我在 GCP 控制台上看到的：

我还添加了 HPA :

apiVersion: autoscaling/v1
kind: HorizontalPodAutoscaler
metadata:
  name: xxxx-hpa
  namespace: xxx
  labels:
    app: xxx-hpa
spec:
  scaleTargetRef:
    kind: Deployment
    name: xxx-phpfpm
    apiVersion: apps/v1
  minReplicas: 1
  maxReplicas: 10
  targetCPUUtilizationPercentage: 60

谢谢，问候

谢谢@apisim 的评论我发现了问题... HPA 命令，因此如果 minReplicas 为 1，则生产中将只有一个 pod...

谢谢问候
