Does not work on cross platform build

[andrejohansson]

I might be missing something, but for me this does not work on either linux, windows or macos (see #56) builds.

I'm trying to cross compile a tauri app using the script published here but all platforms fail on this action.

Since I fail on all platforms...am I missing something here? I´ve put up an epheremal key in tailscale admin console and added it to secrets.

linux failure

The tricky part with linux is that it´s reporting success but it´s actually failing.

Are there any plans for this to work on windows?

[bradfitz]

It should work fine on Linux.

macOS and Windows should be possible but we haven't done the work yet.

[andrewgbell]

Windows would be handy since the hosted runners don't allow linux containers, so the idea would be to connect to a linux runner to use the container there...

Copying from #93

If using private Windows CI runners, Tailscale could be installed on the underlying machine instead of being part of the Action.

We cannot easily add support for Windows runners supplied by GitHub because installation requires Administrator rights. We'd have to run the Windows Tailscale in userspace-networking mode, which means it would require all of the other binaries in the Action to support SOCKS5 or HTTP Proxies. https://tailscale.com/kb/1112/userspace-networking/
