5 Steps for Creating Templates and Virtual Machines on Proxmox using Linux Distro's Cloud Images

This tutorial guides you through the process of creating Templates and Virtual Machines on Proxmox using cloud-based images from various Linux distributions. We provide clear instructions for Alma Linux 9, Amazon Linux 2, CentOS 9, Fedora 38, Oracle Linux 9, RHEL 9, Rocky Linux 9, and Ubuntu 23.04 Lynx Lobster.

Note: The instructions have been tested on Proxmox 8.0.4.

Let's begin by choosing the cloud-based image. If you already have your preferred Linux distribution, skip to the 1st step.

To assist in making informed choices when selecting a Linux distribution for your virtual machines, we've compiled a table showcasing key characteristics of each cloud image. This table provides a snapshot of important attributes, including kernel version, Python version, number of processes initialized after boot, number of packages installed, free memory after boot, VM disk size, root partition disk size, used size on t

HAProxy and Let's Encrypt

HAProxy is a open-source TCP/HTTP load-balancing proxy server supporting native SSL, keep-alive, compression CLI, and other modern features.

Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. Let’s Encrypt is a service provided by the Internet Security Research Group (ISRG).

Concept

This guide is designed for people like myself who seem to find all guides on LetsEncrypt reverse proxies to be like this or any of this

This will cover portainer setup and eventually standarderd CLI only setup

With Portainer

Get onto Linux system
Install docker-ce
Install Portainer

Create a new repository, or reuse an existing one.

Generate a new SSH key:

ssh-keygen -t rsa -C "[email protected]"

Copy the contents of the file ~/.ssh/id_rsa.pub to your SSH keys in your GitHub account settings.

Test SSH key:

Installing Urbackup on CentOS using ZFS

Here's the details on installing Urbackup on the ZFS file system on the stable CentOS 7.

Install CentOS 7. I'll be using the Minimal install.
- Once you have the .iso, write it to a CD or USB drive. I recommend using Rufus if you're on Windows to write it to USB.
- Go ahead and boot to it.
- Most of the defaults on the Installation Summary page should be good. However you will want to:
  - Confirm the time zone is correct.
  - Click the disk you want to install to.

	# Backup
	docker exec CONTAINER /usr/bin/mysqldump -u root --password=root DATABASE > backup.sql

	# Restore
	cat backup.sql \| docker exec -i CONTAINER /usr/bin/mysql -u root --password=root DATABASE

	sudo apt-key add nginx_signing.key && rm nginx_signing.key
