docker-ce添加國內源-阿里docker-hub鏡像

問題現象：

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

問題解決：

開啓iptables對bridge的數據進行處理

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

systctl  --system

sysctl -p

docker添加國內docker-hub源

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

注意：aliyuncs.com是阿里的經典網路形式，能夠在公網解析，給力阿里雲！！！

systemctl daemon-reload && systemctl restart docker

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