When there are mistakes when starting docker mapped to host: / usr / bin / docker-current: Error response from daemon: driver failed programming external connectivity on endpoint sc_mysql (1bc03030afe9f722ae1e6b46166172a70cf87bcc3f02f0acdac0be2a7f0f0036):
(iptables failed: iptables --wait -t nat -A DOCKER -p tcp -d 0/0 --dport 3306 -j DNAT --to-destination 172.17.0.2:3306 ! -i docker0: iptables: No chain/target/match by that name.
[Root @ seichung] pkill docker # terminate the process
[Root @ seichung] iptables -t nat -F # Clear all chains of nat table
[Root @ seichung] ifconfig docker0 down # stop docker default bridge
