Docker Interface Conflict

There may be times when the docker interface IP conflicts with a network. To see the docker interface, run the command ip a It will show a response as follows. In this case, the docker interface has an IP address of 172.17.0.1

An IP address conflict with the docker interface is a rare event, since the IP address range selected for the docker interface is one that should not be widely used. But if it is, then the following steps will stop the service and disable the interface from appearing. Run these commands, in order, from the device's remote shell:
sudo systemctl stop docker
sudo systemctl disable docker
ip link delete docker0
ip a ... to check the interface has disappeared
Once this is done, the docker interface will not appear, even after a reboot.
