kind: Deployment
metadata:
name: nginx-io
namespace: default
spec:
replicas: 1
selector:
 matchLabels:
   app: nginx-io
template:
 metadata:
   labels:
     app: nginx-io
 spec:
   volumes:
     - name: nginx-html
       configMap:
         name: nginx-io-html
   containers:
     - name: nginx
       image: nginx:stable-perl
       ports:
         - containerPort: 80
       volumeMounts:
         - name: nginx-html
           mountPath: /usr/share/nginx/html/
