Add locales to the LMS Docker container

If you have problems running the LMS Docker because of missing locales, you can add the following init script to the Docker config folder. In this example the locale de_DE is added to the container.

#!/bin/sh

if locale -a | grep ^de_DE ; then
    echo "Locale de_DE already installed..."
else
    apt-get update && apt-get -y install locales && sed -i '/de_DE.UTF-8/s/^# //g' /etc/locale.gen && locale-gen
fi

Save this as a script called custom-init.sh in the configuration folder and make sure that it has the execution flag set (chmod +x custom-init.sh).
