Simple deploymenet of Pretalx in 2025

OS Debian 12
Install Docker
Create folder for your project and all files (run this only once):

mkdir -p pretalx pretalx/conf && cd pretalx && touch docker-compose.yml && touch conf/pretalx.cfg

	# into their own files, which makes it possible to use them to configure
	# the VPN using Ubuntu's network manager

	# Usage example:
	# >> ovpnconvert username.dev.ovpn

	sed '1,/<ca>/d;/<\/ca>/,$d' $1 > $1.ca.crt
