以yaml文件的方式运行nginx服务

deployment名字为:nginx,保证运行3个Pod.service名字为：nginx-svc。映射到主机端口：31234.

[root@kbs01 ~]# vim nginx.yaml

apiVersion: extensions/v1beta1
kind: Deployment
metadata:  
	  name: nginx
spec:  
	   replicas: 3  
	   template:    
	   	metadata:     		
			labels:        
				name: nginx    
	   	spec:     
	   		containers:      
	   		- name: nginx       
	   	  	  image: 192.168.226.10:5000/nginx

apiVersion: v1
kind: Service
metadata:  
	name: nginx-svc
spec:  
	selector:    
		name: nginx  
	type: NodePort  
	ports:  
	- port: 80    t
          targetPort: 80    
          nodePort: 31234

[root@kbs01 ~]# kubectl apply -f nginx.yaml
deployment.extensions/nginx createdservice/nginx-svc created
查看pod和service：
[root@kbs01 ~]# kubectl get pod -o wide

[root@kbs01 ~]# kubectl get service -o wide

访问网页验证：
[root@kbs01 ~]# curl 192.168.226.10:31234
