Launcher script not working with local storage on OSX

[silkimen]

Hi Gary,

the launcher script is failing on my OSX machine, when I'm trying to run it with a local storage folder. Do you have an idea?

MAC-SILK:grav-playground sefa$ mkdir docker-grav-storage

MAC-SILK:grav-playground sefa$ docker run -i --rm garywiz/docker-grav --task get-launcher | sh
Extracting run-docker-grav.sh ...

The run-docker-grav.sh script is a quick-start for launching
the garywiz/docker-grav image.

When you launch the container, a fully configured working Grav instnace will be
available at http://localhost:8080/

To get this message again:
   docker run -i --rm garywiz/docker-grav --task get-help LAUNCHER

Or, for geeneral help on the image itself:
   docker run -i --rm garywiz/docker-grav --task get-help

MAC-SILK:grav-playground sefa$ ./run-docker-grav.sh 
Using attached storage at /Users/sefa/Entwicklung/grav-playground/docker-grav-storage

--create-user failure: Error while trying to add user: sefa
