# The current version of cloud-init in the Hypriot rpi-64 is 0.7.9
# When dealing with cloud-init, it is SUPER important to know the version
# I have wasted many hours creating servers to find out the module I was trying to use wasn't in the cloud-init version I had
# Documentation: http://cloudinit.readthedocs.io/en/0.7.9/index.html

# Set your hostname here, the manage_etc_hosts will update the hosts file entries as well

Kubernetes on Hypriot

These are instructions for standing up a Kubernetes cluster with Raspberry Pis with the current Hypriot (1.9.0), with K8S v1.10.5

Thanks to https://gist.github.com/alexellis/fdbc90de7691a1b9edb545c17da2d975 and https://gist.github.com/aaronkjones/d996f1a441bc80875fd4929866ca65ad for doing all the hard work!

Pre-reqs:

• This was done using a cluster of 5 RPi 3 B+
• All Pi's are connected via a local ethernet switch on a 10.0.0.0/24 LAN
