Networking Can'；不要删除法兰绒插件

我正在尝试将网络插件从法兰绒切换到其他东西，只是出于教育目的

法兰绒是通过以下方式安装的：

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

所以为了摆脱它，我想

kubectl delete -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

因此，我得到：

k8s@k8s-master:~$ kubectl delete -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
Error from server (NotFound): error when deleting "https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml": clusterroles.rbac.authorization.k8s.io "flannel" not found
Error from server (NotFound): error when deleting "https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml": clusterrolebindings.rbac.authorization.k8s.io "flannel" not found
Error from server (NotFound): error when deleting "https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml": serviceaccounts "flannel" not found
Error from server (NotFound): error when deleting "https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml": configmaps "kube-flannel-cfg" not found
error when stopping "https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml": timed out waiting for the condition

这很奇怪，因为几个小时前我用weave进行了这样的操作，效果很好。

我在输出中得到了类似的错误：

kubectl delete -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
Error from server (NotFound): error when deleting "https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml": podsecuritypolicies.policy "psp.flannel.unprivileged" not found

解决方案是改变步骤的顺序，首先重新安装kubernetes环境，然后在损坏的环境上重新部署flannel，然后删除它

kubeadm reset

systemctl daemon-reload && systemctl restart kubelet

kubeadm init --pod-network-cidr=10.244.0.0/16

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

kubectl delete -f https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml

注意：您可能还需要手动卸载法兰驱动程序，即vxlan模块：

rmmod vxlan

请使用kubectl检查是否存在无法删除的对象，并将结果添加到您的问题中。
