新集群和 linkerd - 即不启动

Question

我遇到了一个问题，我正在尝试在我的集群上安装 linkerd，一切顺利

我完全按照这个官方 README

https://linkerd.io/2.11/tasks/install-helm/

通过 helm 安装它

MacBook-Pro-6% helm list -n default
NAME        NAMESPACE   REVISION    UPDATED                                 STATUS      CHART           APP VERSION
linkerd2    default     1           2021-12-15 15:47:10.823551 +0100 CET    deployed    linkerd2-2.11.1 stable-2.11.1

linkerd 本身可以工作，linkerd check 命令也可以

MacBook-Pro-6% linkerd version
Client version: stable-2.11.1
Server version: stable-2.11.1

但是当我尝试按照 getting-started 页面中的描述安装 viz 仪表板时，我运行

linkerd viz install | kubectl apply -f -

和

linkerd check
...
Status check results are √

Linkerd extensions checks
=========================
/ Running viz extension check

它会继续检查可视化扩展，当我运行 linkerd dashboard（我知道已弃用）显示相同的错误时

Waiting for linkerd-viz extension to become available

有人知道我做错了什么吗？在这部分卡了 2 小时 &_& 似乎没有人有任何答案

请注意，当我运行、linkerd check 安装 viz 后，我得到

Answer 1

根据你的问题描述：

‼ linkerd-viz pods are injected could not find proxy container for grafana-8d54d5f6d-cv7q5 pod see https://linkerd.io/2.11/checks/#l5d-viz-pods-injection for hints

和：

MacBook-Pro-6% helm list -n default

我遇到了类似的问题，但使用的是 flagger pod 而不是 grafana pod（我没有像您那样尝试安装 grafana 组件）。

我的问题的副作用是：

$ linkerd viz dashboard
Waiting for linkerd-viz extension to become available
Waiting for linkerd-viz extension to become available
Waiting for linkerd-viz extension to become available
... ## repeating for 5 minutes or so before popping up the dashboard in browser.

我的问题的原因原来是我将 viz 扩展安装到 linkerd 命名空间中。它应该属于 linkerd-viz 命名空间。

查看您最初的问题描述，您似乎将控制平面安装到 default 命名空间（与 linkerd 命名空间相对）。虽然您可以使用任何您想要的命名空间，控制平面必须位于与 viz 扩展不同的命名空间中。详情可以看我这里写的讨论：
