# 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](https://docs.docker.com/engine/install/) and [docker-compose](https://docs.docker.com/compose/install/) 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.

## 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!
