安裝升級(jí)iptables所需依賴

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

編譯安裝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
 # 當(dāng)然可以把cd /usr/local/sbin下面的iptables相關(guān)的東西打包然后分發(fā)到其它服務(wù)器
cd /usr/local/sbin
 \cp iptables /sbin
\cp iptables-restore /sbin/
\cp iptables-save /sbin/

重啟 kube-proxy 與 kubelet

service kube-proxy restart
service kubelet restart
# 再次觀察已經(jīng)沒(méi)有此日志出現(xiàn)一切恢復(fù)正常。
