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.seabee.me --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.
