Description
I use the official yml file to deploy the flannel plug-in through kubeclt apply -f, but the pod status is always error, and there is no clear error information in the kubectl logs. I checked the br_netfilter module according to the flannel installation requirements, the cni plug-in is also installed, and the vxlan module is also loaded. The firewall is turned off. What is going on?
kubectl logs kube-flannel-ds-6s9xx -n kube-flannel
Defaulted container "kube-flannel" out of: kube-flannel, install-cni-plugin (init), install-cni (init)
