我尝试删除终结器，但没有执行任何操作。还尝试使用--grace-period=0 --force删除内容。它不会在名称空间下显示任何资源。

我还能采取其他措施来强制删除吗？

Answer 1

您遇到的错误是由于apiservice v1alpha1.tap.linkerd.io无法正常运行（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：

如果您不需要该API，只需删除即可：kubectl delete apiservice v1alpha1.tap.linkerd.io。
如果需要，您可以尝试删除与其相关的Pod，以便重新启动它们，看看是否有帮助。

之后，您应该能够删除提到的命名空间。

请告诉我是否有帮助。

Answer 2

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

删除处于“终止”状态的链接器kubernetes命名空间
