Create a User and Pre-Auth Key
Commands below use $HEADSCALE_CONTAINER. Set it once per shell session on the dedicated server (change the value if your compose project name differs; find it with docker ps):
export HEADSCALE_CONTAINER=headscale-headscale-1
docker exec -it "$HEADSCALE_CONTAINER" headscale -c /etc/headscale/config.yaml user create homelab
docker exec -it "$HEADSCALE_CONTAINER" headscale users list
docker exec -it "$HEADSCALE_CONTAINER" headscale preauthkeys create --user 1 --expiration 1h
Copy the printed key — you'll use it once on each device you join.
About
--expiration: it only limits the window in which the key can register a new device. Devices already joined stay authorized after the key expires. Use a longer expiration (e.g.24h) or--reusablewhen onboarding several devices.
