I have the following yaml file with replica set with 3 but when I deploy it on GKE in the yaml and in the console the number of replicas is only one.
When I deploy the pods are created but then are terminated. I forgot something?

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

This is what I see on GCP console :

[EDIT]

I also add the 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

Thank you, regards

Thank you @apisim with his comment I found the problem...
The HPA commands, so if minReplicas is 1 there will be only one pod in production...

Thanks Regards
