@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

@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.

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

Root of the problem is platform type (arm or x64).
➜ ~ docker run --privileged --pid=host --rm -it --platform=linux/amd64 justincormack/nsenter1 /usr/bin/tree /src
setns:mnt: Invalid argument
➜ ~ docker run --privileged --pid=host --rm -it --platform=linux/arm64 justincormack/nsenter1 /usr/bin/tree /src

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-linuxkit
but the version installed by apt-get install linux-headers-generic is
/lib/modules/5.4.0-187-generic

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/nsenter1
Then:
$ cd /src
$ cp kheaders.tar.xz /mnt_host/Users/<your username>/wherever
