Tailscale

Client setup

1. Install Tailscale client

curl -fsSL https://tailscale.com/install.sh | sh

2. Create a pre-auth key on your Headscale server

docker exec headscale headscale preauthkeys create --user 1 --reusable --expiration 24h

Copy the key that's generated.

3. Connect to your Headscale server

sudo tailscale up --login-server=https://headscale.conorbriggs.com.au --authkey=YOUR_PREAUTH_KEY --hostname=rpi3

Replace YOUR_PREAUTH_KEY with the key from step 2.

4. Verify connection

# On Raspberry Pi:
sudo tailscale status

# On your Headscale server:
docker exec headscale headscale nodes list

You should see your Raspberry Pi listed with the hostname "raspberry-pi" and an IP like 100.64.0.2.
