SLE 15 SP5 Kernel Module Development Container

Description

The SLE 15 SP5 Kernel Module Development Container Image includes all necessary tools to build kernel modules for SLE and SLE Micro. It is intended to be used for building out-of-tree kernel modules in restricted environments for the SLE kernel.

Usage

The image can be used to launch a container and build a kernel module. The following example below shows how to do this for the DRBD kernel module:

$ podman run --rm -it --name drbd-build registry.suse.com/bci/bci-sle15-kernel-module-devel:15.5
# zypper -n in coccinelle tar
# curl -Lsf -o - https://pkg.linbit.com/downloads/drbd/9/drbd-9.2.11.tar.gz | tar xzf -
# cd drbd-9.2.11/
# make -C drbd all KDIR=/usr/src/linux-obj/$(uname -m)/default

The built kernel module is then available in /drbd-9.2.11/drbd/build-current/drbd.ko. It can be copied to the host system as follows:

$ podman cp drbd-build:/drbd-9.2.11/drbd/build-current/drbd.ko .
$ sudo modprobe drbd.ko

Alternatively, the kernel module can be built as part of a container build using a Dockerfile:

FROM registry.suse.com/bci/bci-sle15-kernel-module-devel:15.5
ENV DRBD_VERSION=9.2.11
WORKDIR /src/
RUN zypper -n in coccinelle tar

RUN set -euxo pipefail; \
    curl -Lsf -o - https://pkg.linbit.com/downloads/drbd/9/drbd-${DRBD_VERSION}.tar.gz | tar xzf - ; \
    cd drbd-${DRBD_VERSION}; \
    make -C drbd all KDIR=/usr/src/linux-obj/$(uname -m)/default

Build the container image, launch the container, and copy the kernel module to the local machine:

$ buildah bud --layers -t drbd-ko .
$ podman run --name drbd drbd-ko
$ podman cp drbd:/src/drbd-9.2.11/drbd/build-current/drbd.ko .
$ podman rm drbd
