Linkerd - 升级后没有 controller 吊舱（掌舵升级）

Question

今天我把linkerd从2.10升级到了2.11，但是升级之后我的controller pod好像不存在了，

我升级了

helm upgrade --namespace v3-mainapp linkerd2 linkerd/linkerd2 --atomic

它给了我

Release "linkerd2" has been upgraded. Happy Helming!
NAME: linkerd2
LAST DEPLOYED: Thu Dec 30 07:42:15 2021
NAMESPACE: v3-mainapp
STATUS: deployed
REVISION: 3
TEST SUITE: None
NOTES:
The Linkerd control plane was successfully installed 🎉

To help you manage your Linkerd service mesh you can install the Linkerd CLI by running:

  curl -sL https://run.linkerd.io/install | sh

Alternatively, you can download the CLI directly via the Linkerd releases page:

  https://github.com/linkerd/linkerd2/releases/

To make sure everything works as expected, run the following:

  linkerd check

Linkerd Viz extension can be installed by running:

  linkerd viz install | kubectl apply -f -

但是当我运行linkerd check时，它给了我一个关于No running pods for "controller"的错误，并且kubectl get po --all-namespaces --selector linkerd.io/control-plane-component=controller返回 no resources

我已尝试重新进行升级，但结果相同

没关系，我想通了，看起来我的 linkerd cli 已经过时了，他们改变了检查的方式，我跑了

curl -sL https://run.linkerd.io/install | sh

再次，现在控制平面正在通过
