kubernetes - `helm init` 说分蘖已经在集群上，但不是吗？

问题描述

vagrant@ubuntu-xenial:~$ helm init 
$HELM_HOME has been configured at /home/vagrant/.helm.
Warning: Tiller is already installed in the cluster.
(Use --client-only to suppress this message, or --upgrade to upgrade Tiller to the current version.)
vagrant@ubuntu-xenial:~$ helm ls
Error: could not find tiller

我该如何进一步诊断？

以下是当前正在运行的 pod kube-system：

vagrant@ubuntu-xenial:~$ kubectl get pods -n kube-system
NAME                                      READY   STATUS      RESTARTS   AGE

解决方案

问题在于部署/服务帐户不存在。

vagrant@ubuntu-xenial:~$ kubectl get deployment tiller-deploy --namespace kube-system
NAME            READY   UP-TO-DATE   AVAILABLE   AGE
tiller-deploy   0/1     0            0           24h


vagrant@ubuntu-xenial:~$ kubectl get events --all-namespaces
kube-system     4m52s       Warning   FailedCreate    replicaset/tiller-deploy-7f4d76c4b6                 Error creating: pods "tiller-deploy-7f4d76c4b6-" is forbidden: error looking up service account kube-system/tiller: serviceaccount "tiller" not found

我删除了部署并helm init再次运行，然后运行：

kubectl delete deployment tiller-deploy --namespace kube-system
helm init
