Introduction

This repository holds files that are used by students in the Unixerius / ITVitae training "Introduction to DevSecOps".

  • The "Lab setup" folder has the files needed to build the workstation used in class.
  • The "Lab slides and exercises" folder has PDFs with the exercises we do in class.
  • The "Pipelines" folder has the example YAML files for the Azure DevOps pipelines that we build in class.

Workstation setup.

Requirements

Students are required to bring their own laptop.

The laptop should be somewhat recent, built in or after 2020.

  • It must have 8GB of RAM, or more.
  • It needs at least 50GB of free storage space.
  • It should have either an Intel i5/i7/i9, AMD Ryzen, or Apple Silicon (ARM) CPU.

Overview

In order to prepare your laptop for the "Introduction to DevSecOps" class, you will need to install a virtual machine with tools. I have prepared everything for you, all the hard work's been done. You just need to follow a few steps, after installing one or two pieces of software.

Which instructions you follow, depends on your host OS (the operating system on your laptop) and the architecture (which CPU is in there). The table provides an overview of my recommended approach. Only choose the fallback options if my recommended option does not work for you.

Laptop OS Architecture Recommended install Fallback option
Windows 10/11 x86_64 / amd64 HyperV
Vagrant
**Requires Win Pro or Edu
VirtualBox
Vagrant
Linux x86_64 / amd64 VirtualBox
Vagrant
n.a.
MacOS x86_64 Homebrew
VirtualBox
Vagrant
n.a.
MacOS Silicon / aarch64 Homebrew
Qemu
Vagrant
Homebrew
UTM
Vagrant

After installing the required software, you must download a Vagrant configuration file as per the instructions. You will then use Vagrant to create the VM in your chosen virtualization tool. Vagrant will make the VM, download the OS and do all the software installations.

Instructions

Follow ONE of the following sets of instructions, based on your choice from the table above.

Using these instructions you will do the following:

  1. Download and install the required software.
  2. Download a Vagrant configuration file and use it to setup a new Vagrant project.
  3. Use Vagrant to create and install the VM.

dso's Issues

Vagrant build on Windows 11 is SLOW

  • Building my Vagrant VM on MacOS aarch64 is incredibly fast.
  • Building the VM on Vagrant with Virtualbox on MacOS x86 is something I need to test again.
  • Building the VM on Windows 11 on my AMD Ryzen is incredibly slow. Much slower than it used to be.

The problem is mostly in Docker on the Ubuntu VM. Pulling images and verifying the hashes is crazy slow. Which is weird, because based on top output, the VM is doing almost nothing.
