节点上的 Flannel 总是重新启动。

日志如下:

root@debian:~# docker logs faa668852544

主配置: ubuntu: 16.04

节点:

embedded system with debian rootfs(linux4.9).
kubernetes version:v1.14.1
docker version:18.09
flannel version:v0.11.0

我希望法兰绒在节点上运行正常。

首先,要让 flannel 正常工作,您必须传递--pod-network-cidr=10.244.0.0/16给 kubeadm init。

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

通过运行设置/proc/sys/net/bridge/bridge-nf-call-iptables1

sysctl net.bridge.bridge-nf-call-iptables=1 

接下来是创建clusterrole和clusterrolebinding

如下:

kubectl apply -f https://raw.githubusercontent.com/coreos/flannel/a70459be0084506e4ec919aa1c114638878db11b/Documentation/kube-flannel.yml
