删除Kuma网格(独立的k8s安装)

Question

即使删除名称空间kuma-system及其资源，也不会重置控制平面GUI中显示的信息。我做错了什么？

Answer 1

您可以使用几乎与安装它的命令相同的命令来删除Kuma。

$ ./kumactl install control-plane | kubectl apply -f -

将apply更改为delete应该能做到这一点。

为了确认这一点，我很快将Kuma安装在我的集群中。

$ kubectl get all --all-namespaces | grep kuma
kuma-system   pod/kuma-control-plane-774956d9c5-zh4vj                             0/1     Running   0          11s
kuma-system   service/kuma-control-plane     ClusterIP   10.8.130.242   <none>        5681/TCP,5682/TCP,443/TCP,5676/TCP,5678/TCP,5653/UDP   14s
kuma-system   deployment.apps/kuma-control-plane                         0/1     1            0           13s
kuma-system   replicaset.apps/kuma-control-plane-774956d9c5                         1         1         0       13s

然后把它移走

$ ./kumactl install control-plane | kubectl delete -f -

现在，我的集群中没有Kuma资源。

$ kubectl get all --all-namespaces | grep kuma
(nothing found)
