This directory contains the configuration for the virtual machines we will use for the installation.
A few prerequisites are handled by the VM provisioning steps.
- Install the
br_netfilter
kernel module that permits kube-proxy to manipulate IP tables rules. - Add the two tunables
net.bridge.bridge-nf-call-iptables=1
andnet.ipv4.ip_forward=1
also required for successful pod networking.
- Set the default DNS server to be Google, as we know this always works.
- Set up
/etc/hosts
so that all the VMs can resolve each other
- Install configs for
vim
andtmux
