docker安裝mysql5.7出現錯誤 docker: Error response from daemon。。。。。

錯誤現象 =>

啓動 rancher server 時出現網絡故障，以下：

docker: Error response from daemon: driver failed programming external connectivity on endpoint peaceful_sammet (0ffcb446e5de6905d872c4e20080243fce8f9928d68b857f6b4a23eadc38f2f3): iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 8080 -j DNAT --to-destination 172.17.0.2:8080 ! -i docker0: iptables: No chain/target/match by that name.

 (exit status 1).
 

解決辦法 =>

pkill docker                         #終止進程
iptables -t nat -F                 #清空nat表的全部鏈
ifconfig docker0 down        #中止docker默認網橋
brctl delbr docker0             #刪除網橋
systemctl restart docker       #重啓docker
