卸载kubesphere导致移入企业空间的项目被删除

brosoul

于华为云的 k8s 集群上，部署 KubeSphere 2.1.0 后，执行 kubectl delete -f https://raw.githubusercontent.com/kubesphere/ks-installer/master/kubesphere-minimal.yaml 进行卸载操作，但是连带着将之前移入新创建企业空间的 namespace 删除！而kubesphere 相关的 ns 却没有删除（如 kubesphere-logging-system kubesphere-monitoring-system 等），则需要手动 delete。
希望快速可以复现并修复这个问题，避免严重损失！！
同时也需要给出一个安全，干净，优美的卸载 KubeSphere 的办法说明！！！

以下是k8s 版本信息

方案一：搬运工，来自于 ks 微信群的分享：

nss=(kubesphere-alerting-system kubesphere-controls-system kubesphere-devops-system kubesphere-logging-system kubesphere-monitoring-system kubesphere-system)
ress=(svc deploy sts pvc job cronjob cm)
for ns in ${nss[@]};do
for res in ${ress[@]};do
echo “delete -n$ns $res”
kubectl delete $res -n$ns –all
done
done

kubectl delete pv –all
kubectl delete daemonset -nkubesphere-monitoring-system –all

kubectl get all –all-namespaces
kubectl get pvc –all-namespaces
kubectl get pv
