Warning

By default this cluster requires a total of 9GB RAM. You can change this in the Vagrantfile.

Prerequisites

The following programs need be installed:

• vagrant
• ansible
• virtualbox

With vagrant you need to set the default provider for the virtual machines. This tells vagrant which backend to use for virtualization.

export VAGRANT_DEFAULT_PROVIDER=virtualbox

You can use different backends: https://developer.hashicorp.com/vagrant/docs/providers/default

TODO

• Kubernetes need different mac-addresses per worker. Check if this is provided which virtualbox.

• Turn off swap permanently.

• 3 GB of RAM for all machines.
