minikube mount options

[nicks]

Currently, you can mount a local folder into the minikube VM with something like:

minikube start --mount --mount-string="$PWD:/home" --driver docker

ctlptl should support something like this. The most bare-bones way to support it would be to have a pass-through way to set minikube options, as described here: https://github.com/tilt-dev/ctlptl/issues/86

But one of the goals of ctlptl is to have apis that are a bit abstracted above the underlying implementation engine (whether it's a VM vs a docker container, or Kind vs Minikube), so i wonder if we could offer a better config-based option that would also work on Kind
