Mac でストレージ ドライバーを devicemapper に変更しようとしています。Mac OS X で docker ストレージ ドライバーを変更するの手順に従っていました
しかし、次のエラーが発生しました。私のdocker for macは最新バージョンです。
$ docker-machine create --driver virtualbox --engine-storage-driver devicemapper test2

You can attempt to regenerate them using 'docker-machine regenerate-certs [name]'.
Be advised that this will trigger a Docker daemon restart which will stop running containers.
