gulag-dockerized

World's sexiest gulag setup using docker-compose, IPv6 and Cloudflare. Host- and distro- agnostic... Docker enables easy deployment in any environment that can run Docker, IPv6 lets you have an isolated web server even if you already have a web server on your single IPv4, and Cloudflare provides IPv4 and TLSv1.0 compatibility for you.

Prerequisites

• Linux host with publically routable block of IPv6 addresses and latest versions of Docker and docker-compose installed.

• A domain name added to Cloudflare. You can get a domain for free at http://dot.tk.

1. Enable IPv6 in Docker

• See https://docs.docker.com/config/daemon/ipv6/

• Find your host's global IPv6 + prefix length (i.e. 2605:a140:2045:1635::1/64) under your network interface (i.e. eth0) in ip a.

• Decide on a subnet to provide to Docker. You can use the reference below. For example, I'm using 2605:a140:2045:1635:69::/80. Put this in your daemon.json and restart docker.

IPv6 Subnet Reference Prefix Lengths:

2402:9400:0000:0000:0000:0000:0000:0001
XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX:XXXX

2. Set up gulag-dockerized

• cd /opt or wherever you want

• git clone https://gitea.moe/lamp/gulag-dockerized.git --recursive && cd gulag-dockerized

• cp -r config-template config

• Edit all files in config folder as necessary. Replace all instances of example.com with your domain, add your API keys, etc.

• Run docker-compose up -d mysql && docker-compose logs -f & to initialize the database and start following logs in background.

• Once that's finished, run docker-compose up -d to bring up the rest of the containers. You can type fg and then press ctrl C to stop the log output.

• Find nginx IPv6 address: docker inspect gulag-dockerized_nginx_1 | grep GlobalIPv6Address. Example: 2605:a140:2045:1635:69:242:ac11:8. Add this to your Cloudflare DNS...

3. Set up Cloudflare

• Configure your DNS like so:

• On the SSL/TLS tab, make sure mode is set to Flexible.

4. Use in OSU

• Find OSU and open file location.

• Copy the shortcut to your Desktop.

• Edit the shortcut, and in the Target field, add -devserver <yourdomain>.

• Use this shortcut to launch OSU with your gulag server!
