troubleshooting docker when using DNS .....
Raw
gistfile1.txt
If you have set up your system, so that you can run dns-docker and run into trouble.
Trouble:
$ sudo service docker restart
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.
Files you should look into:
(1) /etc/default/docker
The 2 lines starting with 'DOCKER_OPTS' should be commented-out
# Use DOCKER_OPTS to modify the daemon startup options.
#DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.4.4"
#DOCKER_OPTS="--dns 172.16.0.9 --dns 172.16.0.7"
- the file in control should now be /etc/docker/daemon.json
(2) /etc/docker/daemon.json
for instance :
{
"dns": ["172.17.0.1", "172.16.0.9", "172.16.0.7"],
"bip":"172.17.0.1/24"
}
one file that can be involved
(3) more /etc/resolv.conf
Check the logs!
$sudo systemctl status docker.service
