OS-Dependent Details

Mac

The simples possible way to configure the Docker daemon on Mac is to use the UI: the whale icon-> Preferences -> Daemon.

The "Basic" section has UI elements to configure insecure registries and registry mirrors.

The "Advanced" section gives access to the content of "daemon.json" file, which can be edited freely. However, the danger is that a configuration error saved here will prevent the daemon to start. If that happens, the file-system version of the same file can be accessed as follows:

cd ~/Library/Containers/com.docker.docker/Data/database 
git reset --hard HEAD

The daemon.json becomes available as:

~/Library/Containers/com.docker.docker/Data/database/com.docker.driver.amd64-linux/etc/docker/daemon.json

The file can be edited and committed, and the daemon restart.
