kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml
kubectl get pods --namespace=kube-system		
		
		

		
kubectl expose deployment nginx --port=88 --target-port=80 --type=NodePort --name=nginx-service	
kubectl describe service nginx-service	
		
			

		
将服务暴露出去，在服务前面加一个负载均衡，因为pod可能分布在不同的结点上。 
–port：暴露出去的端口 
–type=NodePort：使用结点+端口方式访问服务 
–target-port：容器的端口 
–name：创建service指定的名称		
		
			

		
kubectl expose deployment nginx --port=80 --target-port=8080 --type=NodePort
kubectl expose deployment nginx --port=80 --target-port=8080 --type=LoadBalancer	
		
			

		
kubectl create deployment registry --image=registry:latest
kubectl get deploy		
		
			

			
kubectl delete deployment hello-minikube			
			
			

		
kubectl scale -n default deployment nginx --replicas=1	
kubectl scale deployment springbootdemo --replicas=4	
kubectl scale deployment nginx --replicas=10

kubectl rollout history deployment/nginx		
		
			

指定版本号

		
kubectl rollout history deployment/nginx --revision=3

kubectl rollout undo deployment/nginx-deployment --to-revision=3		
		
			

			
root@netkiller ~/neo (master)# kubectl rollout restart deployment netkiller -n project			
			
			

更新资源对象的容器镜像

可使用资源对象包括（不区分大小写）：pod (po)、replicationcontroller(rc)、deployment(deploy)、daemonset(ds)、job、replicaset (rs)

			
kubectl set image deployment/nginx nginx=nginx:1.20.0
kubectl set image deployment/nginx busybox=busybox nginx=nginx:1.10.1
			
			

携带参数

			
kubectl set image deployments,rc nginx=nginx:1.9.1 --all		
			
			

使用通配符

			
kubectl set image daemonset abc *=nginx:1.9.1
