3 months ago @farhadh the information about the kernel and the patches applied to it are all in the VM. You can try docker run --privileged --pid=host --rm -it justincormack/nsenter1 /usr/bin/tree /src
Is that enough for your use case? Can you give us more details about what you're trying to achieve? Maybe we can make things better

3 months ago @dgageot Thanks for your attention. I need the Linux kernel GTP tunneling module in my LinuxVM kernel for which I need the headers to compile its C code.

2 months ago @n-bes which version of Docker Desktop are you testing it with? It was added only recently.

2 months ago Root of the problem is platform type (arm or x64).

1 month ago it would be great to get the linux headers published soon. meanwhile, the version is 6.6.31, as in:
Unable to locate package linux-headers-6.6.31-linuxkitbut the version installed by apt-get install linux-headers-generic is
/lib/modules/5.4.0-187-generic

1 month ago Would love an update here; I also need the 6.6.31 headers for eBPF.
Edit: Well, 6.6.32 after today's update.
I did figure out you can yoink these right out of the host container:
docker run \
-v "$(pwd):/app" \
--privileged \
--pid=host \
--rm \
-it \
--platform=linux/arm64 \
justincormack/nsenter1Then:
$ cd /src
$ cp kheaders.tar.xz /mnt_host/Users/<your username>/wherever
Description
The latest LinuxKit kernel headers for kernel 6.6.22 are not available on Docker Hub. The latest one available is 6.6.13. This causes malfunctions in the building of kernel modules against the latest Docker desktop version.
Reproduce
docker pull linuxkit/kernel:6.6.22-build docker pull linuxkit/kernel:6.6.22
