处理方法：

[ERROR FileContent--proc-sys-net-bridge-bridge-nf-call-iptables]: /proc/sys/net/bridge/bridge-nf-call-iptables contents are not set to 1

[root@k8snode1 k8s_images]# echo "1" >/proc/sys/net/bridge/bridge-nf-call-iptables
 

   [ERROR Swap]: running with swap on is not supported. Please disable swap
[preflight] If you know what you are doing, you can make a check non-fatal with `--ignore-preflight-errors=...`

[root@k8snode2 k8s_images]# swapoff -a
[root@k8snode2 k8s_images]# vim /etc/fstab
