Evaluating Azure Linux

While Microsoft announce #Azure #Linux 4.0, releases are not publicly available to download as disk image or container image to pull. So instead, I have looked at the slightly older 3.0 release that is published at mcr.microsoft.com/azurelinux/base/core:3.0.

To best test this, I added this to my dotfiles targets and created a container image that can be used with my dev-command to set up a contained system for development purposes. This works, but points out some very clear differences and annoyances

Very minimal footprint; great from a security perspective and low on resources.

There is no dnf. Instead tdnf has to be used.

Lima on runner

Have been testing a bit more with Lima and other cncf-projects. Got my own prepped cloud images now start with lima instead of the macadam tool I worked on before. Seems to work, but some minor issues along the way; issues filed and let's see. So far, glad to actually move to a more community maintained stack of tooling.

Test openSUSE cloud image with machine

Needs macadam from: https://github.com/gbraad-dotfiles/macadam/releases/tag/v0.2.1a as this provides UEFI firmware support.

git config -f ~/.config/dotfiles/local/machine.ini \
    'disks.opensuse-cloud' \
    'https://download.opensuse.org/tumbleweed/appliances/openSUSE-Tumbleweed-Minimal-VM.x86_64-Cloud.qcow2'

Import devenv WSL image into container runtime

Note

This will describe in short how to get your old wsl environment running in a container runtime, such as containerd or Podman. While it is possible to use vhdx, I had better results with tarballs. A vhdx needs to be converted, use qemy-nbd etc, as you can not boot this as a VM unless you install the kernel and modules.

Prepare WSL export

Here's how you configure it: First, configure your KORG DRUMLOGUE AS FOLLOWS:

• Press SHIFT+LIVE[GLOBAL]
• Press RS/7 ---- Set Channel to 1-12 (Note, you need Firmware upgrade 1.1) ---- Route: Pick your MIDI Connection (USB or USB+MIDI]

Here’s how to map your LaunchPad Pro MK3 to Drumlogue like in the video, using Novation Components:

Logue BackgroundFX

Store the runtime descriptor passed during initialization so we can access the get_raw_input() API later during rendering.

  // Runtime descriptor for background effect support
  // Provides access to get_raw_input() API which returns audio input unaffected by effect on/off state
  // This enables the effect to run continuously without requiring HOLD (XY Freeze) to be pressed
  static unit_runtime_desc_t s_runtime_desc;
