This is the Dockerfile for my setup.

ARG FROM=alpine

FROM ${FROM}

RUN \
apk add \
bash \
bison \
diffutils \
elfutils-dev \
emacs \
flex \
gcc \
git \
linux-headers \
make \
# c library
musl-dev \
nano \
openssl-dev \
perl \
python3 \
# useradd
shadow \
sudo \
tar

I used linux-next-20241108 for the test kernel.
