k8s1.16.0 +flannel+kube-proxy出现 --random-fully解决

出现错误日志日志

kube-proxy 日志：I0923 10:19:59.443659  543401 proxier.go:1729] Not using `--random-fully` in the MASQUERADE rule for iptables because the local version of iptables does not support it
kubelet日志：I0923 11:24:47.087532    1941 kubelet_network_linux.go:111] Not using `--random-fully` in the MASQUERADE rule for iptables because the local version of iptables does not support it
持续不间断出现这样的错误
按照错误日志提示iptables 本地版本不支持升级iptables 

安装升级iptables所需依赖

yum install gcc make libnftnl-devel libmnl-devel autoconf automake libtool bison flex  libnetfilter_conntrack-devel libnetfilter_queue-devel libpcap-devel

编译安装iptables

export LC_ALL=C
wget wget https://www.netfilter.org/projects/iptables/files/iptables-1.6.2.tar.bz2
tar -xvf iptables-1.6.2.tar.bz2
cd iptables-1.6.2
 ./autogen.sh
 ./configure
 make -j4
 make install
 # 当然可以把cd /usr/local/sbin下面的iptables相关的东西打包然后分发到其它服务器
cd /usr/local/sbin
 \cp iptables /sbin
\cp iptables-restore /sbin/
\cp iptables-save /sbin/

重启 kube-proxy 与 kubelet

service kube-proxy restart
service kubelet restart
# 再次观察已经没有此日志出现一切恢复正常。
