kubernetes - 删除 Kuma 网格（独立 k8s 安装）

Question

即使删除命名空间kuma-system及其资源也不会重置控制平面 GUI 中显示的信息。我究竟做错了什么？

Answer 1

您可以使用几乎与安装它相同的命令来删除 Kuma。

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

更改apply为delete应该可以解决问题。

为了确认这一点，我迅速在我的集群上安装了 Kuma

$ 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

然后将其删除

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

现在，我的集群上没有 Kuma 资源

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