Could not find a ready tiller pod (Error)

6/21/2019

I set up helm and tiller. I have tiller-deploy . yesterday , i could regularly run. But today I get this error message

Error: could not find a ready tiller pod

How can i fix it. Some info which i tried by command.

It can't get server infomation .

$ helm version
Client: &version.Version{SemVer:"v2.14.1", 
GitCommit:"5270352a09c7e8b6e8c9593002a73535276507c0", GitTreeState:"clean"}
Error: could not find a ready tiller pod

I have a running tiller-deploy-675656bbcf-5q5gp.

$ kubectl get pods -n kube-system
NAME                                   READY   STATUS    RESTARTS   AGE
tiller-deploy-675656bbcf-5q5gp         1/1     Running   0          46h
tunnelfront-557bbd9fb5-b8g7h           1/1     Running   0          47h

Check the deployed thing.

$ kubectl get deploy -n kube-system
NAME                   READY   UP-TO-DATE   AVAILABLE   AGE
tiller-deploy          0/1     1            0           46h
tunnelfront            0/1     1            0           47h

I faced the same issue. In my case, i was revoked RBAC and added back. When I first initiated helm, I had created the service accounts. I was then revoked access to the cluster and added back. Not exactly sure if this was the cause but when trying to do helm ls i get that error.

I tried the helm init --upgrade as suggested by Alexey but was not successful.

I restarted the tiller pod and everything worked again. Shrugs

In my case

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