mixed normal and preemtible kubernetes cluster
# Kubernetes clusters using preemtible instances
## Motivation
People experimenting with kubernetes clusters on the GKE not
necessarily have money to keep a full cluster on at all time. GKE
clusters can be easily resized, but this still incurs in the full
instance cost when the cluster is up.
Google has added preemptible instances that are ideal for many

vboxnet1

[ for some reason it started at 0, now it is 1 for me ]

to avoid sleep interferences:

  • put the following in /etc/NetworkManager/NetworkManager.conf
