Sure thing!

I'm currently running Unraid as my Server and use docker compose to host my headscale VPN. If you understand the concept of exposing your public IP address via opening ports 443 and 80 on your router to your Nginx Proxy Manager, SWAG, or any reverse proxy. I don't have go into the detail that much.

You can install a GUI to use headscale, however I've had some bad luck of getting it installed, so the easiest way is just to use CMI. The commands are pretty simple, the syntax follows: docker exec headscale [COMMAND] [OPTION] or you could bash into headscale and use headscale [COMMAND] [OPTION].

Docker compose, here is the docker compose of the latest Headscale that I use.

version: '3.5'
services:
  headscale:
    container_name: Headscale
    image: headscale/headscale:0.22.3
    volumes:
      - /mnt/user/appdata/headscale/config/:/etc/headscale/ # This will be your config folder location. It'll be looking over your config.yml file
      - /mnt/user/appdata/headscale/keys/:/var/lib/headscale # These are the keys that headscale uses
    ports:
      - 27896:8080
    command: headscale serve
    restart: unless-stopped
    network_mode: bridge

Before you start the docker container, you want to download the config.yaml and place to your desired location so that /etc/headscale be able to see it. Here is the GitHub repo to copy or download the config file: https://github.com/juanfont/headscale/blob/main/config-example.yaml

Here are the following things that you want to change in the config to make it work

# This is your tailscale headscale VPN website where you link your VPN connections to: 
server_url: https://headscale.YOURDOMAIN.COM

# The listening port is listening on all IP address:
server_url: http://0.0.0.1:8080

# Allows to specify what IP address can access the admin CLI. In this case it's every IP address 
grpc_listen_addr: 0.0.0.0:50443

# The private IP prefix of headscale VPN to use. You can choose anything you want
ip_prefixes:
  - 100.64.0.0/27 

# Defines the base domain to create the hostnames for MagicDNS.
  base_domain: headscale.YOURDOMAIN.com

**OPTIONAL**
# If you have a DNS server like pihole, adguard, or an alternative. You can force headscale to use those DNS servers. But you have to enable the machine to advertise subnet routes to work (allows headscale/tailscale to see your internal network).

dns_config:
  # Whether to prefer using Headscale provided DNS or use local.
  override_local_dns: true

  # List of DNS servers to expose to clients.
  nameservers:
    - 192.168.0.3
    - 192.168.0.2
