Pod无法在PodCIDR中获取IP，获取docker IP

Kubernetes版本（使用

kubectl版本

）：

环境： -云提供商或硬件配置： -OS（例如从/etc/OS发布）：CentOS 7.2 -内核（例如

uname-a

）：4.9.0 -安装工具：裸金属

发生了什么事 将新节点添加到现有集群，并将pod调度到新节点。pod的IP不在PodCIDR的范围内，请使用docker网桥IP

对新节点有bean调度。ip为

新节点上的kubelet都有如下日志

有人能帮我吗？我试着用两天的时间来解决这个问题。非常感谢

这个问题已经解决，我关闭这个问题。 问题是我在稍后添加到集群的节点上注释kubelet.service中的cni config标志
