Containerfile

# **IMPORTANT NOTE:**
# NOTE: This DOES NOT WORK FOR GPU until vulkan supports NON COMPUTE WORKLOADS.
# this is just a "scratchpad" for testing vkcube, but unfortunately I did not realize it was NOT a compute-based workload
# and more support is needed for display / GPU workloads. For now (see startup.sh) we are using the CPU for rendering. by supplying the 
# VK_ICD_FILENAMES env var to the vulkan loader.
# 
# **Description:**
#
# This is a "hello world" GPU container that showcases
# how we can use the Mac Silicon GPU within a container via showing the standard vkcube demo.
# 
# **Technical Description:**
# You must use Podman Desktop with Podman 5.2.0 or above and run a
# podman machine with libkrun support.
# 
# For a more technical TLDR it is:
# * Creates a virtualized Vulkan GPU interface
# * Virtualized GPU is passed to a vulkan-to-metal layer on the host MacOS
# * Uses https://github.com/containers/libkrun for all of this to work.
#
# Source code:
# In order for this to work, a patched version of mesa / vulkan is used. The source for this is located here: https://download.copr.fedorainfracloud.org/results/slp/mesa-krunkit/fedora-39-aarch64/07045714-mesa/mesa-23.3.5-102.src.rpm
# 
# The following patch is applied from within the source code to get the patched mesa / vulkan to work correctly: `0001-virtio-vulkan-force-16k-alignment-for-allocations-HA.patch`
#
# **Running:**
#
# ```sh
# podman run -d \
# -p 6080:6080 \
# --device /dev/dri
# vulkan-mac-silicon-gpu-vkcube
# ```
#
# Then visit http://localhost:6080 in your browser.
