Helm 'Error: error installing: namespaces "{username}" not found'

Question

我正在使用 Minikube 来修补 Helm。

我明白了Helm installs tiller in the kube-system namespace by default:

The easiest way to install tiller into the cluster is simply to run helm init... Once it connects, it will install tiller into the kube-system namespace.

但它试图在以我命名的命名空间中安装 tiller:

$ ~/bin/minikube start
* minikube v1.4.0 on Ubuntu 18.04
* Tip: Use 'minikube start -p ' to create a new cluster, or 'minikube delete' to delete this one.
* Starting existing virtualbox VM for "minikube" ...
* Waiting for the host to be provisioned ...
* Preparing Kubernetes v1.16.0 on Docker 18.09.9 ...
* Relaunching Kubernetes using kubeadm ...
* Waiting for: apiserver proxy etcd scheduler controller dns
* Done! kubectl is now configured to use "minikube"
$ helm init
$HELM_HOME has been configured at /home/mcrenshaw/.helm.
Error: error installing: namespaces "mcrenshaw" not found
$

我可以指定 tiller 命名空间，但我必须在以后每次使用 helm 时指定它。

$ helm init --tiller-namespace=kube-system
$HELM_HOME has been configured at /home/mcrenshaw/.helm.

Tiller (the Helm server-side component) has been installed into your Kubernetes Cluster.

Please note: by default, Tiller is deployed with an insecure 'allow unauthenticated users' policy.
To prevent this, run `helm init` with the --tiller-tls-verify flag.
For more information on securing your installation see: https://docs.helm.sh/using_helm/#securing-your-helm-installation
$ helm upgrade --install some-thing .
Error: could not find tiller
$ helm upgrade --install some-thing . --tiller-namespace=kube-system
Release "some-thing" does not exist. Installing it now.

我假设在每个命令中指定命名空间是可以的。但是感觉不对。我做了什么破坏了我的 Helm 配置吗？

更新：

根据 Eduardo 的要求，这是我的 helm 版本：

$ helm version --tiller-namespace=kube-system
Client: &version.Version{SemVer:"v2.15.0", GitCommit:"c2440264ca6c078a06e088a838b0476d2fc14750", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.15.0", GitCommit:"c2440264ca6c078a06e088a838b0476d2fc14750", GitTreeState:"clean"}

设置 Tiller 默认命名空间有两种方式：

使用 --tiller-namespace 标志（因为您已经在使用）。
通过设置 $TILLER_NAMESPACE 环境变量。

标志配置优先于环境配置。您可能设置了此环境变量（您可以使用 printenv TILLER_NAMESPACE 检查）。如果是这样，unset 它和进一步的 helm 命令应该正确指向 kube-system 命名空间。
