Linkerd - 升級后沒有 controller 吊艙（掌舵升級）

Question

今天我把linkerd從2.10升級到了2.11，但是升級之后我的controller pod好像不存在了，

我升級了

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

它給了我

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 -

但是當我運行linkerd check時，它給了我一個關於No running pods for "controller"的錯誤，並且kubectl get po --all-namespaces --selector linkerd.io/control-plane-component=controller返回 no resources

我已嘗試重新進行升級，但結果相同

沒關系，我想通了，看起來我的 linkerd cli 已經過時了，他們改變了檢查的方式，我跑了

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

再次，現在控制平面正在通過
