If you check the startup logs, you’ll notice this:
"Plugins": [],
which means that no plugins are loaded. You should not specify any Plugins entry in your config file, the image will take care of it.
This error has already been observed a few times. It seems upgrading Docker might help (see 1.12.4 crashing). If you find a way to reproduce it, let me know.
Best regards,
