k8s helm 删除 tiller

kuberneter 上面装了 helm 想卸载还并不是那么简单,

bash 复制代码

kubectl get -n kube-system secrets,sa,clusterrolebinding -o name|grep tiller|xargs kubectl -n kube-system delete
kubectl get all -n kube-system -l app=helm -o name|xargs kubectl delete -n kube-system

先查看 pod

bash 复制代码

[root@k8snode1 ~]# kubectl get pods --all-namespaces

执行第一条命令

bash 复制代码

[root@k8snode1 ~]# kubectl get -n kube-system secrets,sa,clusterrolebinding -o name|grep tiller|xargs kubectl -n kube-system delete
secret "tiller-token-z9bml" deleted
serviceaccount "tiller" deleted
warning: deleting cluster-scoped resources, not scoped to the provided namespace
clusterrolebinding.rbac.authorization.k8s.io "tiller" deleted
[root@k8snode1 ~]#

再执行第二条命令

bash 复制代码

[root@k8snode1 ~]# kubectl get all -n kube-system -l app=helm -o name|xargs kubectl delete -n kube-system 
pod "tiller-deploy-5cdbdd477f-bj54f" deleted
service "tiller-deploy" deleted
deployment.apps "tiller-deploy" deleted
replicaset.apps "tiller-deploy-5cdbdd477f" deleted
[root@k8snode1 ~]#

再次查看 pod, tiller 已经被卸载。
