tailscale installation

[Bogdan1001]

Hey,

I'm trying to achieve that this instance be available only from tailscale network, but I'm receiving "tailscaled got signal terminated; shutting down" after it started, a machine on a few seconds appears on my tailscale dashboard as connected and then gone after a few seconds.

the last docker file:
