# Vagrant
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
## Kernel Settings
|
||
|
|
|
||
|
|
1. Disable cgroups v2. I found that Kubernetes currently doesn't play nice with cgroups v2, therefore we need to set a kernel boot parameter in grub to switch back to v1.
|
||
|
|
1. Install the `br_netfilter` kernel module that permits kube-proxy to manipulate IP tables rules
|
||
|
|
1. Add the two tunables `net.bridge.bridge-nf-call-iptables=1` and `net.ipv4.ip_forward=1` also required for successful pod networking.
|
||
|
|
|
||
|
|
## DNS settings
|
||
|
|
|
||
|
|
1. Set the default DNS server to be Google, as we know this always works.
|
||
|
|
1. Set up `/etc/hosts` so that all the VMs can resolve each other
|
||
|
|
|
||
|
|
## Other settings
|
||
|
|
|
||
|
|
1. Install configs for `vim` and `tmux` on master-1
