Introduction
Tailscale is a VPN service that uses WireGuard to create a fast, secure, and simple peer-to-peer network. Tailscale is a zero config VPN that works on any platform, service, or runtime. It encrypts all connections using WireGuard and integrates with 100+ tools for easy deployment and management.
Tailscale is a modern VPN built on top of Wireguard. It works like an overlay network between the computers of your networks - using NAT traversal.
Everything in Tailscale is Open Source, except the GUI clients for proprietary OS (Windows and macOS/iOS), and the control server.
The control server works as an exchange point of Wireguard public keys for the nodes in the Tailscale network. It assigns the IP addresses of the clients, creates the boundaries between each user, enables sharing machines between users, and exposes the advertised routes of your nodes.
A Tailscale network (tailnet) is private network which Tailscale assigns to a user in terms of private users or an organisation.
Self Hosting
You can self host a Tailscale server with Headscale + Headscale UI.
Headscale is an open source, self-hosted implementation of the Tailscale control server. Headscale's goal is to provide self-hosters and hobbyists with an open-source server they can use for their projects and labs. It implements a narrow scope, a single Tailnet, suitable for a personal use, or a small open-source organisation.
Headscale UI is a web frontend for the headscale Tailscale-compatible coordination server.

Docker
You can self host a Tailscale server with Headscale + Headscale UI + Traefik docker containers.
Follow the instructions on the respective web sites and the YouTube (outdated though!) video to get started, including grabbing copies of the docker compose and headscale config/config.yaml files, then edit the first 3 options as follows ...
server_url: https://headscale.mydomain.com listen_addr: 0.0.0.0:8080 metrics_listen_addr: 0.0.0.0:9090
Running headscale in a container
This is the directory layout for a Docker Compose method ...
/root/docker/stacks/headscale
|-- config
| `-- config.yaml
|-- data
| |-- db.sqlite
| `-- noise_private.key
|-- docker-compose.yaml
`-- run
`-- headscale.sock
3 directories, 5 files
... and this is the docker compose YAML file which has both Headscale and Headscale UI containers ...
services:
headscale:
container_name: headscale
volumes:
- ./config:/etc/headscale/
- ./data:/var/lib/headscale/
- ./run:/var/run/headscale/
ports:
- 8080:8080
- 9090:9090
image: headscale/headscale:0.23.0-alpha12
environment:
- TZ=Europe/London
command: serve
restart: unless-stopped
networks:
traefik:
ipv4_address: 172.19.0.28

- "traefik.enable=true"
- "traefik.docker.network=traefik"
- "traefik.http.routers.headscale.rule=PathPrefix(`/`) && Host(`headscale.mydomain.com`)"

headscale-ui:

networks:
traefik:
external: true
Start up the containers, and you should see these lines in the docker logs ...
headscale | 2024-05-31T10:53:13+01:00 INF Opening database database=sqlite3 path=/var/lib/headscale/db.sqlite

headscale-ui | {"level":"info","ts":1717149193.4059176,"msg":"serving initial configuration"}
Test the headscale server with curl and the docker image ...
curl 0.0.0.0:9090/metrics docker exec headscale headscale --help docker exec headscale headscale version docker exec headscale headscale nodes list docker exec headscale headscale apikeys list
Navigate to the Headscale UI web address you provided in the config.yml file with /web at the end - https://headscale.mydomain.com/web) and then you will see an error about Authentication and missing API key.
Generate your server's API key. You only get one chance to see this ...
docker exec headscale headscale apikeys create
... copy it, then go the Headscale UI Settings page and paste it there with your 'server_url' from the config file.
There is NO save settings button, it does it automatically but you can then press the Test Server Settings button.
Yay - you have successfuly set up your own self-hosted Tailscale server! :-)
Now you can add your first client device.
Client Devices
Linux
Software Installation
Native
curl -fsSL https://tailscale.com/install.sh | sh
Docker
To be done.
https://hub.docker.com/r/tailscale/tailscale
Users
Generate a User on the Headscale server first, then register a Node linked to that User.
docker exec headscale headscale users create <USER_NAME>
Nodes
Method 1: Register a machine using normal login
On a client machine, run the tailscale login command, which will output a machine key (mkey) ...
sudo tailscale up --login-server <YOUR_HEADSCALE_URL>
On the server, run the headscale nodes command to register that client machine node using that mkey to a User ...
docker exec headscale headscale nodes register --key <mkey:YOUR_MACHINE_KEY> --user <USER_NAME>
Method 2: Register a machine using a pre authenticated key
Generate a key linked to a User ...
docker exec headscale headscale preauthkeys create --reusable --expiration 24h --user <USER_NAME>
This will return a pre-authenticated key that can be used to connect a node to headscale during the tailscale login command on the client ...
sudo tailscale up --login-server <YOUR_HEADSCALE_URL> --authkey <YOUR_AUTH_KEY>
