There is an easy-to-use docker container for TON Proxy:
https://github.com/kdimentionaltree/ton-proxy-docker

You can run TON Proxy on your server in a few simple steps below if you already have some website running on port 80.

1. git clone https://github.com/kdimentionaltree/ton-proxy-docker.git
2. cd ton-proxy-docker
3. docker-compose build
4. ./init.sh
5. docker-compose up -d

Also note that on 4th step you will get some output in terminal that is important. You will see two separate strings, one of these will be lower-case. It is ADNL address of your server so URL to open it will look like:
ufbeczhf4ayygzjnvzgnmiko4vacfkqte34khurt5nfvxwvsem7dued.adnl

After your website is available with raw ADNL address, you can add the DNS record on dns.ton.org to link it with your domain.
