解决:
pod和svc cidr有冲突造成,重新指定cidr解决
我现在遇到和你一样的问题了,请问
pod和svc cidr有冲突造成,重新指定cidr解决
具体如何操作 我看我的两个网段确实不一样
[root@k8s-master1 pki]# kubectl describe cm kubeadm-config -n kube-system |grep Subnet
podSubnet: 10.244.0.0/16
serviceSubnet: 10.96.0.0/12
你这个cidr正确的,应该是其他问题导致的:
检查下kubeadm init cidr和cni里面的是否匹配了。
请问你的问题解决了吗?我遇到了和你相同的问题,麻烦帮忙解答一下
需要查一下cni的pod网段配置
