问题1

Container runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized

原因 没有网络插件

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

问题2

kubectl get nodes  not Ready 

进入到 没有  Ready  的node

systemctl  status kubelet

Container runtime network not ready" networkReady="NetworkReady=false reason:NetworkPluginNotReady message:docker: network plugin is not ready: cni config uninitialized"

 因为缺少网络cni所以 把master cni 拷贝过来就可以了

scp  master:/etc/cni/net.d/*  /etc/cni/net.d/

问题3

发现某个pod 没有起来

kubectl logs --tail=10  -n kube-flannel kube-flannel-ds-clssq 

问题4:

Error registering network: failed to acquire lease: node “master“ pod cidr not assigne

vim /etc/kubernetes/manifests/kube-controller-manager.yaml

加入

--allocate-node-cidrs=true

各模块配置路径

kubelet 

/etc/systemd/system/kubelet.service
