I ran into the problem that if you configure the daemon according to the instructions Getting Started , then after the docker update all settings are lost.
It is necessary to change the recommendation from editing the file
/lib/systemd/system/docker.service to creating file
override.conf in directory
[Service] ExecStart= ExecStart=/usr/bin/dockerd -H fd:// -D -H tcp://127.0.0.1:2375
After updating the docker, the settings will not be lost.
