我尝试删除终结器，但什么也没做。还尝试使用 --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:

1. 如果您不需要该 API，只需将其删除:kubectl delete apiservice v1alpha1.tap.linkerd.io。

2. 如果您需要，您可以尝试删除与其相关的 pod 以重新启动它们，看看是否有帮助。

之后您应该能够删除您提到的命名空间。

如果有帮助，请告诉我。
