The DAX header (2 MiB of NVDIMM metadata + a duplicate MBR) is unconditionally prepended to every image by set_dax_header(). NVIDIA images use virtio-blk-pci with disable_image_nvdimm=true, so the kernel reads MBR #1 directly and never touches the DAX metadata -- it is dead weight. Add a SKIP_DAX_HEADER environment variable (default "no") that, when set to "yes", skips the DAX header entirely: - Removes the 2 MiB DAX overhead from image size calculations in both the erofs and ext4 paths - Skips the set_dax_header() call, avoiding compilation and execution of the nsdax tool - Passes the variable through to containerised builds Enable SKIP_DAX_HEADER=yes for both install_image_nvidia_gpu() and install_image_nvidia_gpu_confidential() in the build pipeline. All other image builds are unaffected (default remains "no"). Signed-off-by: Fabiano Fidêncio <ffidencio@nvidia.com>
Kata Containers packaging
Introduction
Kata Containers currently supports packages for many distributions. Tooling to aid in creating these packages are contained within this repository.
Build in a container
Kata build artifacts are available within a container image, created by a
Dockerfile. Reference DaemonSets are provided in
kata-deploy, which make installation of Kata Containers in a
running Kubernetes Cluster very straightforward.
