1 kube-proxy报错 "--random-fully"

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

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
# 覆盖
cd /usr/local/sbin
\cp iptables /sbin
\cp iptables-restore /sbin/
\cp iptables-save /sbin/
可以把/usr/local/sbin下面的iptables相关的东西打包然后分发到其它服务器

重启 kube-proxy 与 kubelet
systemctl restart kubelet.service kube-proxy.service
