我尝试删除终结器，但什么也没做。还尝试用 --grace-period=0 --force 删除仍然没有。它不显示命名空间下的任何资源。

我还能做些什么来强制删除？

Answer 1

您遇到的错误是由 api 服务 v1alpha1.tap.linkerd.io 不工作 (ServiceNotFound) 引起的。很难说是什么原因造成的，但我可以看到两种解决方法：

如果您不需要那个 API 而不是简单地删除它：kubectl delete apiservice v1alpha1.tap.linkerd.io.
如果需要，可以尝试删除相关的pods重启一下看看有没有用

之后您应该可以删除您提到的命名空间。

如果有帮助，请告诉我。

Answer 2

您可以运行 linkerd uninstall | kubectl delete -f - 它将按正确的顺序删除资源，因此不会发生此错误。
