@renevo I have been trying to bootstrap your project with Hypriot 1.10 configuring wifi instead of the ethernet interfaces. I was trying to start with this guide: https://blog.hypriot.com/post/setup-kubernetes-raspberry-pi-cluster/ but found that I needed to back-step to this page for an example user-data: https://blog.hypriot.com/faq/. Basically by placing that section in the wifi.yml to pass to flash I do see that the /etc/wpa_supplicant/wpa_supplicant.conf file is updated and has the correct information in it - however the interface does not look to be using any of the settings with a check of ifconfig to see an associated IP (I am, of course, able to tell this by plugging in an ethernet cable to get to the box and verifying the contents of the file). Are there more example user-data files / yml that use the RPi wifi for a kubernetes cluster?
