1. Download the Headscale binary https://github.com/juanfont/headscale/releases, and place it somewhere in your PATH or use the docker container
```shell
docker pull headscale/headscale:x.x.x
```
<!--
or
```shell
docker pull ghrc.io/juanfont/headscale:x.x.x
``` -->
```shell
docker pull headscale/headscale:x.x.x
```
<!--
or
```shell
docker pull ghrc.io/juanfont/headscale:x.x.x
``` -->
2. (Optional, you can also use SQLite) Get yourself a PostgreSQL DB running
```shell
docker run --name headscale -e POSTGRES_DB=headscale -e \
POSTGRES_USER=foo -e POSTGRES_PASSWORD=bar -p 5432:5432 -d postgres
```
```shell
docker run --name headscale -e POSTGRES_DB=headscale -e \
POSTGRES_USER=foo -e POSTGRES_PASSWORD=bar -p 5432:5432 -d postgres
```
3. Set some stuff up (headscale Wireguard keys & the config.json file)
```shell
wg genkey > private.key
wg pubkey < private.key > public.key # not needed
```shell
wg genkey > private.key
wg pubkey < private.key > public.key # not needed
# Postgres
cp config.json.postgres.example config.json
# or
# SQLite
cp config.json.sqlite.example config.json
```
# Postgres
cp config.json.postgres.example config.json
# or
# SQLite
cp config.json.sqlite.example config.json
```
4. Create a namespace (a namespace is a 'tailnet', a group of Tailscale nodes that can talk to each other)
```shell
headscale namespaces create myfirstnamespace
```
or docker:
```shell
docker run -v ./private.key:/private.key -v ./config.json:/config.json headscale/headscale:x.x.x headscale namespaces create myfirstnamespace
```
```shell
headscale namespaces create myfirstnamespace
```
or docker:
the db.sqlite mount is only needed if you use sqlite
```shell
docker run -v $(pwd)/private.key:/private.key -v $(pwd)/config.json:/config.json -v $(pwd)/derp.yaml:/derp.yaml -v $(pwd)/db.sqlite:/db.sqlite -p 127.0.0.1:8000:8000 headscale/headscale:x.x.x headscale create myfirstnamespace
```
or if your server is already running in docker:
```shell
docker exec <container_name> headscale create myfirstnamespace
```
5. Run the server
```shell
headscale serve
```
or docker:
```shell
docker run -v $(pwd)/private.key:/private.key -v $(pwd)/config.json:/config.json -v $(pwd)/derp.yaml:/derp.yaml -p 127.0.0.1:8080:8080 headscale/headscale:x.x.x headscale serve
```
```shell
headscale serve

or docker:
6. If you used tailscale.com before in your nodes, make sure you clear the tailscaled data folder
```shell
systemctl stop tailscaled
rm -fr /var/lib/tailscale
systemctl start tailscaled
```
the db.sqlite mount is only needed if you use sqlite
```shell
docker run -v $(pwd)/private.key:/private.key -v $(pwd)/config.json:/config.json -v $(pwd)/derp.yaml:/derp.yaml -v $(pwd)/db.sqlite:/db.sqlite -p 127.0.0.1:8000:8000 headscale/headscale:x.x.x headscale serve
```
6. If you used tailscale.com before in your nodes, make sure you clear the tailscald data folder
```shell
systemctl stop tailscaled
rm -fr /var/lib/tailscale
systemctl start tailscaled
```
7. Add your first machine
```shell
tailscale up -login-server YOUR_HEADSCALE_URL
```
```shell
tailscale up -login-server YOUR_HEADSCALE_URL
```
8. Navigate to the URL you will get with `tailscale up`, where you'll find your machine key.
9. In the server, register your machine to a namespace with the CLI
```shell
headscale -n myfirstnamespace node register YOURMACHINEKEY
```
or docker:
```shell
docker run -v ./private.key:/private.key -v ./config.json:/config.json headscale/headscale:x.x.x headscale -n myfirstnamespace node register YOURMACHINEKEY
```
```shell
headscale -n myfirstnamespace node register YOURMACHINEKEY
```
or docker:
```shell
docker run -v $(pwd)/private.key:/private.key -v $(pwd)/config.json:/config.json -v $(pwd)/derp.yaml:/derp.yaml headscale/headscale:x.x.x headscale -n myfirstnamespace node register YOURMACHINEKEY

or if your server is already running in docker:
```shell
docker exec <container_name> headscale -n myfistnamespace node register YOURMACHINEKEY

2. Use the authkey from your machine to register it
```shell
tailscale up -login-server YOUR_HEADSCALE_URL --authkey YOURAUTHKEY
```
```shell
tailscale up -login-server YOUR_HEADSCALE_URL --authkey YOURAUTHKEY
```
If you create an authkey with the `--ephemeral` flag, that key will create ephemeral nodes. This implies that `--reusable` is true.

### Policy ACLs
Headscale implements the same policy ACLs as Tailscale.com, adapted to the self-hosted environment.
Headscale implements the same policy ACLs as Tailscale.com, adapted to the self-hosted environment.
For instance, instead of referring to users when defining groups you must
use namespaces (which are the equivalent to user/logins in Tailscale.com).
