 Current known env vars are:
 
-TS_AUTHKEY: the authkey to use for login.
-TS_HOSTNAME: the hostname to request for the node.
-TS_ROUTES: subnet routes to advertise.
-TS_DEST_IP: proxy all incoming Tailscale traffic to the given destination.
-TS_TAILSCALED_EXTRA_ARGS: extra arguments to 'tailscaled'.
-TS_EXTRA_ARGS: extra arguments to 'tailscale up'.
-TS_USERSPACE: run with userspace networking (the default) instead of kernel networking.
-TS_STATE_DIR: the directory in which to store tailscaled state. The data should persist across container restarts.
-TS_ACCEPT_DNS: whether to use the tailnet's DNS configuration.
-TS_KUBE_SECRET: the name of the Kubernetes secret in which to store tailscaled state.
-TS_SOCKS5_SERVER: the address on which to listen for SOCKS5 proxying into the tailnet.
-TS_OUTBOUND_HTTP_PROXY_LISTEN: the address on which to listen for HTTP proxying into the tailnet.
-TS_SOCKET: the path where the tailscaled LocalAPI socket should be created.
-TS_AUTH_ONCE: if true, only attempt to log in if not already logged in. If false (the default, for backwards compatibility), forcibly log in every time the container starts.
