Proxmox VE 6.x release includes a feature to add custom cloud-init configs. Unfortunately there is poor documentation, so I had to figure this out by adding pieces of information together.

The custom cloud-init files (user-data, meta-data, network-config)

The cloud-init files need to be stored in a snippet. This is not very well documented:

Go to Storage View -> Storage -> Add -> Directory
Give it an ID such as snippets, and specify any path on your host such as /snippets
Under Content choose Snippets and de-select Disk image (optional)
Upload (scp/rsync/whatever) your user-data, meta-data, network-config files to your proxmox server in /snippets/snippets/ (the directory should be there if you followed steps 1-3)

Introduction

The objective of these instructions is to create a complete Arm64 OS (Userland and Kernel) using Debian Debootstrap and RPI-Update for use on the Raspberry Pi 3 and 4.

Prerequisites:

An existing Debian/Raspbian system (any architecture will do)
An empty SD card formatted as per a standard Raspbian installation mounted to /mnt/sd on the build system
- 1st Partition 0-256MB = FAT32 (Mount to /mnt/sd/boot)
- 2nd Partition 256MB+ = EXT4 (Mount to /mnt/sd)

Set-up basic Debian system

Overview

This is a solution of a common problem with Nexus Docker repositories. The administrator has to expose port for "pull", another port for "push", other ports for each hosted repository. This solution is about leveraging Nginx reverse proxy to avoid using these ports.

How it works ?

Given :

Nexus hostname is "nexus.example.com"
Nexus web port is 8081

Introduction

This document shows how to create a Debian package for an existing Python library.

Before doing this, it is a good idea to check if there isn't an existing Debian package for the library to be packaged.

For Debian: https://www.debian.org/distrib/packages

For Ubuntu: https://packages.ubuntu.com/
