在教程https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/中,它显示为
要使法兰绒正常工作,必须将
--pod-network-cidr=10.244.0.0/16
传递给kubeadm init.
。
如何通过其他cidr,例如--pod-network-cidr=192.168.0.0/16
?
答案 0 :(得分:1)
遵循本教程中的相同步骤,除了:
(1)在kubeadm reset
之后,清除主节点和从节点上的早期网络接口。
sudo ip link del cni0
sudo ip link del flannel.1
sudo systemctl restart network
(2)运行kubeadm init --pod-network-cidr=192.168.0.0/16
(3)下载kube-flannel.yml
文件,将硬编码的10.244.0.0
更改为192.168.0.0
,然后执行kubectl create -f kube-flannel.yml
。

如果要将网络从weavenet
移至flannel
,则在步骤1中,还需要进行sudo ip link del weave
