Question

我正在尝试将网络插件从法兰绒转换为其他用于教育目的的插件。

法兰绒已通过以下方式安装：

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

所以要重新开始我正试图

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

结果我得到了：

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

这是奇怪的，因为几个小时前我已经用weave＆amp; amp;工作得很好。

我在输出中也遇到了类似的错误：

解决方案是更改步骤顺序，先将法兰绒重新部署到损坏的kubernetes环境中，然后再删除它。

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绒驱动程序，它是vxlan模块：

rmmod vxlan

无法删除法兰绒插件
