我到底是怎么得到这个错误消息的：
➜ ~ oc adm policy add-cluster-role-to-user cluster-admin -z tiller --namespace tiller
Error from server (NotFound): the server could not find the requested resource
因此：
➜ ~ oc project
Using project "tiller" on server "https://192.168.99.100:8443".
➜ ~ oc get sa
NAME SECRETS AGE
builder 2 35m
default 2 35m
deployer 2 35m
tiller 2 30m
我不太明白为什么找不到tiller服务帐户。

oc version的输出是什么？您的客户端可能与服务器不兼容。
