Posted 2021-08-14 最小的帆也能远航

现象：

[root@xxxh ~]# docker run -d --restart=always -p 80:80 rancher/server
9d918ae01d60dc5ad749f98cc93fc144231051c7f8ab7a32d873ab6b3157fd38
docker: Error response from daemon: driver failed programming external connectivity on endpoint pensive_panini (fb0be019dff5a5824452718fa556c5d8264e76a2addacadbaf1b8fc23cae2855):  (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 80 -j DNAT --to-destination 10.10.100.2:80 ! -i docker0: iptables: No chain/target/match by that name.
 (exit status 1)).

解决方法：

• docker服务启动时定义的自定义链DOCKER由于某种原因被清掉
• 重启docker服务及可重新生成自定义链DOCKER

systemctl restart docker

或者重启服务器即可
