sig-windows-dev-tools-boxes

Experimental Vagrant boxes for testing https://github.com/kubernetes-sigs/sig-windows-dev-tools setup on Windows host using Virtual Box.

Boxes

WARNING: The boxes have not been optimised for size, just some packages have been removed from Ubuntu boxes (e.g. build tools).

The avaialble custom twaeked versions of test boxes:

• mloskot/sig-windows-dev-tools-ubuntu-2004 based on roboxes/ubuntu2004
• mloskot/sig-windows-dev-tools-ubuntu-2204 based on roboxes/ubuntu2204
• mloskot/sig-windows-dev-tools-windows-2019 based on sig-windows-dev-tools/boxes/windows-2019
• Vanilla OS, without any Kubernetes or containers tools mloskot/sig-windows-dev-tools-windows-2022 based on valengus/windows-2022-standard-core

Features

• VirtualBox Guest Additions 7.0.8 (including workaround for libXt.so missing on Ubuntu 22.04)
• Set explicit VirtualBox OS type
• Disabled VirtualBox GUI features
• Disabled VirtualBox 2D and 3D acceleration
• Disabled VirtualBox Remote Desktop
• Windows box with WinRM startup forced to auto instead of auto (delayed): sc config WinRM start= auto
• Windows Firewall disabled:

  netsh advfirewall show allprofiles
  netsh advfirewall set allprofiles state off
  netsh advfirewall show allprofiles

• Windows Defender Antivirus disabled

Test

.\run_test.ps1 test_ubuntu2204
.\run_test.ps1 test_windows2019

Simple smoke test run vagrant up and vagrant destroy 10 times as poor-man way to determine boot and provisioning times, catch any deviations, discover (WinRM) timeouts and other issues. The runner script saves complete output in log file per test directory.

Build

There is no sophisticated build pipeline using configuration management tools.

The boxes are simply packaged VirtualBox machines:

1. Create VirtualBox machine

   cd windows2019
   vagrant up
   # Apply tweaks - the gist of this project!
   vagrant package --base <machine name> --output <name>.box

2. Upload <name>.box file to app.vagrantup.com

3. Update Vagrantfile-s of tests with new version/box

4. Test with .\run_test.ps1 test_<box>

5. Clone SWDT from https://github.com/kubernetes-sigs/sig-windows-dev-tools

6. Modify its Vagrantfile to use desired new boxes

7. Run SWDT to create cluster using new boxes
