Or later, when the device exits, the tailscaled daemon itself performs tailscale logout which immediately removes the device from your tailnet.

For example, you can add tailscale logout as a last step in your ephemeral node deployment script to immediately remove it from your tailnetĪnother way is if you created an ephemeral device by running tailscaled with the -state=mem: flag.

If you are deploying multiple instances of the same container, use a reusable auth key instead of baking the Tailscale node key into the container image to avoid duplicate devices.
