复制命令
宿主机到pod(单容器)
kubectl cp app-jognx-redis4-ha-server.yaml -n iot hub12345-iop-dm-replicaset-0:/iot/
统一在 cd /opt/iot
删除容器,自动创建容器
dm
更新dm和acl包
dm源文件chart包
cd /var/lib/helmrepo/
helm package --save=false ./dm
helm repo index --url=http://10.17.1.160:8879/charts /var/lib/helmrepo/
helm repo update
cd /opt/iot
docker build -t registry.iot.com:5000/library/iot/dm-and-acl:0.0.1 .
docker push registry.iot.com:5000/library/iot/dm-and-acl:0.0.1
路由
kubectl get virtualservice trident-web -n istio-system -oyaml
强制删除pod
kubectl delete pod hub-test0707-emqtt-mysql-0 -n yanhua --force --grace-period=0
测试helm命令
helm install --name=yuanqianqian4 --namespace=iop . --debug --dry-run
增加rolebinding
kubectl get rolebinding -n yanhua
kubectl edit rolebinding trident-yanhua-rolebinding -n yanhua

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:

- ''
resources:
- pods
verbs:

kubectl create -f rds-cluesterrole.yml
