no-ip2.conf not created about rpi-noip HOT 2 CLOSED

/usr/local/etc/no-ip2.conf is created inside the container.
I create a folder in / named noip, then I launched:
sudo docker run -ti -v "/noip:/usr/local/etc/" hypriot/rpi-noip noip2 -C
The file is then created on the host machine in /noip:

/noip $ ls
no-ip2.conf

You can then run the container with
sudo docker run -d -v "/noip:/usr/local/etc/" --restart=always hypriot/rpi-noip

from rpi-noip.

You can look at the file content by executing docker run --rm -v noip:/usr/local/etc hypriot/rpi-noip cat /usr/local/etc/no-ip2.conf.

from rpi-noip.
