这是最后的报错，也就是 rancher 容器内内置的 K3s 集群启动失败，所以得看k3s 的日志才能继续排查

docker run 启动的容器内置了一个 K3s 集群，要查看这个 K3s 的日志，需要你 restart rancher 容器，然后 exec 到容器内，查 k3s.log 的日志，直到容器崩溃。

Error: iptables is not available on this host : error listing chain “POSTROUTING” in table “nat”: exit status 3: iptables v1.8.11 (legacy): can’t initialize iptables table `nat’: Table does not exist (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.

Usage:
kube-proxy [flags]

Flags:
–add_dir_header If true, adds the file directory to the header of the log messages
–allow_dynamic_housekeeping Whether to allow the housekeeping interval to be dynamic (default true)
–alsologtostderr log to standard error as well as files (no effect when -logtostderr=true)
–application_metrics_count_limit int Max number of application metrics to store (per container) (default 100)
