docker-ce添加国内源-阿里docker-hub镜像

问题现象：

WARNING: bridge-nf-call-iptables is disabled
WARNING: bridge-nf-call-ip6tables is disabled

问题解决：

开启iptables对bridge的数据进行处理

cat > /etc/sysctl.d/docker.conf <<-'EOF'
net.bridge.bridge-nf-call-iptables = 1
net.bridge.bridge-nf-call-ip6tables = 1
EOF

sysctl  --system

sysctl -p

docker添加国内docker-hub源

cat >/etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors":["https://jnxt8d8b.mirror.aliyuncs.com"]
}
EOF

注意：aliyuncs.com是阿里的经典网路形式，可以在公网解析，给力阿里云！！！

systemctl daemon-reload && systemctl restart docker

[root@beng ~]# docker info |grep -i mirror
