Can you paste the logs: journalctl -fu docker

hamzawix commented 6 years ago

Try creating a new bridged network interface and restart the docker service: go to /etc/network/interfaces and add these lines: auto docker0 iface docker0 inet static address 172.17.0.1 netmask 255.255.255.0 bridge_ports eth0 bridge_stp off bridge_fd 0 bridge_maxwait 0 then: sudo systemctl restart networking then restart docker service: sudo systemctl restart docker

good luck

Thanks to @hamzawix for the solution since I run to the same ~issue~ accident myself;

I just added the above lines in a new file as in /etc/network/interfaces.d/dockerif

Restarting docker service solved the issue

sudo service docker restart
