Vagrant & Packer Collection

A collection of infrastructure-as-code configurations for building machine images with Packer and managing virtual machines with Vagrant.

Features

• Packer Templates: HCL2 and JSON templates for building VM images
• Multi-Platform: CentOS 7, Rocky Linux 8.6, Ubuntu 20.04 (GCE), Amazon Linux 2 (AWS)
• Multi-Provider: KVM/QEMU (local), GCP, AWS
• Vagrant Configs: Multi-node cluster provisioning with libvirt
• Automated Setup: Kickstart files for unattended OS installation
• Security Hardening: PAM, SSH, account lockout, login banners, command logging
• VM Lifecycle: Shell scripts for managing VM snapshots, start/stop, rebuild

Quick Start

Build a VM Image with Packer

cd packer/hcl2/rocky
cp rocky.auto.pkrvars.hcl.example rocky.auto.pkrvars.hcl
# Edit rocky.auto.pkrvars.hcl with your values
packer init .
packer build rocky.json.pkr.hcl

Start a Vagrant Cluster

cd vagrant/somaz-v3
vagrant up

Manage VM Lifecycle

./somazenv.sh status    # Show all VM status
./somazenv.sh start     # Start or create VMs
./somazenv.sh stop      # Graceful halt
./somazenv.sh rebuild   # Destroy and recreate all VMs
