Fixed: «docker0: iptables: No chain/target/match by that name»
When i tried to launch a container, docker gave me this error
| 1 | docker: Error response from daemon: failed to create endpoint registry on network bridge: iptables failed: iptables —wait –t nat –A DOCKER –p tcp –d 0/0 —dport 5050 –j DNAT —to–destination 172.17.0.2:5000 ! –i docker0: iptables: No chain/target/match by that name. |
Reason : iptables rules which were inserted during docker restart were removed while i restarted iptables.
Fix : You can fix this by restarting docker service, it will insert the required rules to iptables .
On Centos7
Restart docker service
| 1 | systemctl restart docker.service |
Install iptables-services
| 1 | yum install iptables–services |
And then enable the service using systemd:
| 1 | systemctl enable iptables.service |
Now you can save the rules
| 1 | /usr/libexec/iptables/iptables.init save |
On Centos6 ,
Restart docker using
| 1 | service docker restart |
Now save iptables rules using command
| 1 | iptables–save |
