一、集群部署-查询集群状态
①查询k8s master各组件健康状态：
kubectl get componentstatus②查询k8s node健康状态：
kubectl get node
二、kubectl-管理工具
①创建
kubectl run nginx --replicas=3 --labels="app=example" --image=nginx:1.10 --port=80②查看
kubectl get deploy
kubectl get pods --show-labels
kubectl get pods -l app=example
kubectl get pods -o wide③发布
kubectl expose deployment nginx --port=88 --type=NodePort --target-port=80 --name=nginx-service
kubectl describe service nginx-service④故障排查
kubectl describe TYPE NAME_PREFIX
kubectl logs nginx-xxx
kubectl exec –it nginx-xxx bash⑤更新
kubectl set image deployment/nginx nginx=nginx:1.11
or
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
kubectl scale deployment nginx --replicas=10⑥回滚
kubectl rollout undo deployment/nginx-deployment
kubectl rollout undo deployment/nginx-deployment --to-revision=3⑦删除
kubectl delete deploy/nginx
kubectl delete svc/nginx-service三、Pod管理–创建/查询/更新/删除
① 创建pod资源
kubectl create -f pod.yaml② 查看pods
kubectl get pods nginx-pod③ 查看pod描述
kubectl describe pod nginx-pod④ 更新资源
kubectl apply -f pod.yaml⑤ 删除资源
kubectl delete pod nginx-pod
