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

Hello Pi

This is a writedown of how I installed my raspberry pi(s).

The base is a Proxmox, so I don't have to worry about reformat the SD card every time I wanna try out something new, as I can start VMs and LXC containers, as well as Docker containers once it's configured properly.

Note: Those files are versioned, so you can always look what changed from time to time.

Getting GCP access token from a service account key

Use your service account's key JSON file to get an access token to call Google APIs.

Good for seeing how things work, including the creation of JWT token.

To create a JWT token, you can replace create-jwt-token.sh script with tools like step.

If you just want to get an access token for a service account,

Prometheus Time-Series Database for Monitoring with ZFS

What's Prometheus

Prometheus is an open-source systems monitoring and alerting toolkit originally built at SoundCloud. Since its inception in 2012, many companies and organizations have adopted Prometheus, and the project has a very active developer and user community. It is now a standalone open source project and maintained independently of any company

How to Install Prometheus with ZFS

In this guide we will use Debian based Linux distribution version 10 (Buster). If you are using an Cloud Instance like in Amazon Web Service you can use the default provided Ubuntu Amazon Machine Image (AMI) Debian 10 (Buster) 64-bit when you are provisioning it

	Create a Persistent Volume called log-volume. It should make use of a storage class name manual. It should use RWX as the access mode and have a size of 1Gi. The volume should use the hostPath /opt/volume/nginx

	Next, create a PVC called log-claim requesting a minimum of 200Mi of storage. This PVC should bind to log-volume.

	Mount this in a pod called logger at the location /var/www/nginx. This pod should use the image nginx:alpine.
