Warewulf v4 Provisioning in VirtualBox with Vagrant

Introduction

Vagrant project to provision a Warewulf v4 cluster running CentOS 8.

• mgr - warewulf headnode
• cn0 - warewulf compute node 0
• cn1 - warewulf compute node 1

Prerequisites

You need working VirtualBox and Vagrant installations to use this repository.

All capabilities were developed and tested with:

• macOS 21.0.1
• Oracle VirtualBox 6.1.30 r148432 (without VirtualBox 6.1.30 Oracle VM VirtualBox Extension Pack), and
• Vagrant 2.2.19

Quick Start

If you don't want to (re)configure anything and just want to bring up the manager node and some compute nodes then:

Provision everything in one go...

./bootstrap.sh
vagrant up

In testing, the entire 3 node cluster was fully provisioned and running in under 9 minutes with manager node install and configuration taking the bulk (8 minutes) of that time. Compute nodes boot diskless in under a minute.

Tips

• Preparation of the base system is handled in mgr/warewulf_pre.sh
• Install of Warewulf v4 based on the EL8 Quickstart (Rocky and RHEL) is handled in mgr/warewulf_install.sh
• Configuration based on the EL8 Quickstart (Rocky and RHEL) is handled in mgr/warewulf_config.sh
• Customization through creation of a second container image using Singularity is handled in mgr/warewulf_container.sh

Important

• VirtualBox 6.1.28 introduced a change that breaks this deployement without modification to the host configuration that will not be corrected by bootstrap.sh. Follow the instructions in the Host-Only Networking section of the VirtualBox user guide for instructions for configuration of /etc/vbox/networks.conf.
