Tailscale is a simple VPN service, and often functions well as a low-latency secure overlay network for cluster servers.
I've added a provider which allows
go-discover
to select Tailscale peers by tag via regular expression matching. It might be useful to extend the functionality later to include other ways of searching for peers, but I think this is a good start.In order to bring in the latest Tailscale client library, I believe it requires bumping to go 1.19 which may be infeasible for
go-discover
but I'm not sure at this stage.
