dockder启动报错
Error response from daemon: Cannot restart container b7a: driver failed programming external connectivity on endpoint elasticsearch (395bc4ab3e66b6d66e23fb13067102b3803db6b663658e91de30f57c11030388): (iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 9300 -j DNAT --to-destination 172.17.0.4:9300 ! -i docker0: iptables: No chain/target/match by that name.
(exit status 1))
原因是：docker服务启动时定义的自定义链docker由于某种原因被清掉，
而重启docker服务可以重新生成自定义链docker。
解决方法：
systemctl restart docker
