Error response from daemon: driver failed programming external connectivity on endpoint prickly_turing (081405caf9fe991605f89d0ada69f3cbbd54e0526b9a85fa9b8ea6619e5161ee): iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 8888 -j DNAT --to-destination 172.17.0.2:8080 ! -i docker0: iptables: No chain/target/match by that name.
(exit status 1)
Error: failed to start containers: 29683c3b68ac
原因:
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
