OS-Dependent Details

Mac

I am using Docker for Mac 1.13.0 on MacOS 10.12 and the daemon settings can be accessed via the Docker app (Preferences -> Daemon -> Advanced).

But if you change this to something wrong, you will render your installation unusable (the daemon will no longer start-up). This happened to me.

I found out that the settings are stored in a Git repository in ~/Library/Containers/com.docker.docker/Data/database where I had to issue a git reset --hard HEAD before I could change anything. After that the daemon settings are available in ~/Library/Containers/com.docker.docker/Data/database/com.docker.driver.amd64-linux/etc/docker/daemon.json.

Edit, commit and restart the Docker app … et voilà … the daemon starts again.
