Proxmox

Introduction VM templates in Proxmox provide a powerful way to standardize and accelerate virtual machine deployments. Instead of manually configuring each new VM from scratch, you can create a template once and clone it as many times as needed, ensuring consistency across your infrastructure. Common use cases for VM templates: Rapid deployment of multiple identical servers Testing environments that need to be quickly provisioned and destroyed CI/CD pipeline workers that require consistent configurations Development environments for team members Staging environments that mirror production A template is essentially a read-only VM configuration that serves as a blueprint....

Introduction Terraform enables infrastructure as code (IaC) for Proxmox environments, allowing you to define, version, and automate VM provisioning. Instead of manually creating VMs through the Proxmox GUI, you can declare your desired infrastructure state in configuration files and let Terraform handle the deployment. Benefits of using Terraform with Proxmox: Reproducibility: Identical infrastructure across dev, staging, and production Version Control: Track infrastructure changes in Git alongside application code Automation: Integrate with CI/CD pipelines for automated deployments Documentation: Configuration files serve as living documentation Efficiency: Provision multiple VMs simultaneously with minimal effort Common use cases:...

Introduction Creating a virtual machine in Proxmox VE is straightforward, but the choices you make during setup significantly impact performance and functionality. This guide walks through creating an optimized Ubuntu Server VM with best-practice configurations for production or homelab use. What you’ll learn: Upload an Ubuntu Server ISO to Proxmox storage Create a VM with optimal hardware settings Configure storage, networking, and system options Enable QEMU Guest Agent for better VM management Apply performance tuning for maximum efficiency This guide is ideal for:...

Introduction Cloud-init is a powerful industry-standard tool for automating the initial configuration of virtual machines. Instead of manually setting up each new VM with network settings, user accounts, and SSH keys, cloud-init templates let you deploy pre-configured VMs in seconds. This guide shows you how to create a cloud-init template VM in Proxmox that you can clone repeatedly, with each clone automatically configured with unique settings like IP addresses, hostnames, and SSH keys....

Introduction Running out of disk space on a virtual machine is a common scenario as applications grow and data accumulates. Unlike physical servers, virtual machines in Proxmox make it relatively simple to expand disk capacity without downtime or hardware changes. This guide walks you through safely resizing an Ubuntu VM’s disk in Proxmox, covering both the Proxmox UI configuration and the in-guest partition and filesystem operations needed to make the additional space available to your operating system....
