support for rancher desktop as VM manager

[nicks]

currently, ctlptl uses Docker Desktop as the primary VM manager on Windows/macos.

As more people use Rancher Desktop, we may need to add support for using it as a VM manager too.

Is this closer to reality now that RD is past v1.0?

@TimothyLoyer I haven't really spent much time investigating whether RD has the APIs we would need to support this.

Getting to Docker Desktop support took a bunch of research, and uses some undocumented APIs.

So certainly wouldn't reject a contribution of Rancher Desktop support, just that it's probably non-trivial and the tilt team has already been burned a couple times on adding support for Rancher Desktop APIs that changed out from under us.

That makes sense, thank you for the reply and all your hard work!

Hey everyone!

Loving ctlptl! ... But I'd prefer to use rancher desktop instead of docker desktop :)
It seems rancher desktop is still not supported, can that be?

Running ctlptl apply -f ctlptl.yaml results in:

❯ ctlptl apply -f ctlptl.yaml
