+{% include 'badges.j2' %}
+
+## Description
+
+Th Kernel Module Development Container Image includes all necessary tools to build kernel
+modules for SUSE Linux Micro 6.0. It is intended to be used for building out-of-tree kernel
+modules in restricted environments.
+
+
+## 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:
+```ShellSession
+$ podman run --rm -it --name drbd-build {{ image.pretty_reference }}
+# 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/$(uname -m)/default
+```
+
+The built kernel module is then available in
+`/drbd-9.2.11/drbd/build-current/drbd.ko`. It can be copied to the host system
+as follows:
+```ShellSession
+$ 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`:
+
+```Dockerfile
+FROM {{ image.pretty_reference }}
+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/$(uname -m)/default
+```
+
+Build the container image, launch the container, and copy the kernel module to
+the local machine:
+```ShellSession
+$ 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
+```
