(三) kubectl工具部署应用（上）

1、创建

kubectl run nginx --replicas=3 --labels="app=example" --image=nginx:1.10 --port=80

2、查看

kubectl get all

kubectl get deploy

kubectl get pods --show-labels

kubectl get pods -l app=example

kubectl get pods -o wide

3、发布

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

kubectl describe service nginx-service

外网访问:http://192.168.88.121:31740

内部访问: curl 10.96.16.208:88

4、故障排查

kubectl describe TYPE NAME_PREFIX

kubectl logs nginx-xxx

kubectl exec -it nginx-xxx bash

5、更新

kubectl set image deployment/nginx nginx-nginx:1.11 --record

kubectl edit deployment/nginx

资源发布管理：

kubectl rollout status deployment/nginx

kubectl rollout history deployment/nginx

kubectl rollout history deployment/nginx --revision=3

#扩容副本数

kubectl scale deployment nginx --replicas=10

6、回滚

kubectl rollout undo deployment/nginx-deployment

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

7、删除

kubectl delete deploy/nginx

kubectl delete svc/nginx-service
