Proxmox

Fast initialization of Debian VM using Ansible

Introduction

Virtual machine deployment in Proxmox can be achieved faster by creating virtual machine template with desired settings and then cloning this machine. This new virtual machine requires some changes after cloning so to speed-up this process Ansible can be used. Example how to do this will be shown in this article.

Software used: Proxmox 8, Debian 12 cloud image, Ansible 2.14.3

Quick deployment of Debian cloud image in Proxmox with cloud-init

Introduction

This post demonstrates how to quickly create and afterwards clone virtual machine in Proxmox using Debian cloud image. When not using cloud image, more time must be spent after cloning virtual machine: you need to recreate SSH keys (cloning virtual machine doesn't change host SSH keys and that can cause problems with SSH connection to VMs cloned from same template machine), create new user with SSH access, change partition size when you resize disk in Proxmox, set hostname. All of this can be easily achieved with Debian cloud image because it is using cloud-init and Proxmox has built in support for it. This instruction is for creating virtual machine from cloud image on Proxmox with ZFS filesystem.

Software used: Proxmox 8, Debian 12 cloud image

Full disk encryption with Proxmox and remote decryption through SSH

Introduction

This article shows how to setup encrypted Proxmox hypervisor with remote decryption through SSH. It's useful if you want to protect your data and all virtual machines in case of physical theft of your homelab server. Keep in mind that in order to decrypt the system (for example after system reboot) you need to log in through SSH and enter decryption password.

OS used: Debian 12
Software used: Proxmox 8, KeePassXC 2.7.4
