Kernel Module Management

Attention First published at https://cloud.redhat.com/blog/scale-testing-kernel-module-management Introduction Kernel Module Management (KMM) Operator manages, builds, signs and deploys out-of-tree kernel modules and device plugins on OpenShift Container Platform clusters. KMM adds, for the HUB/Spoke scenario, a new ManagedClusterModule which describes an out-of-tree kernel module and its associated device plugin. You can use ManagedClusterModule resources to configure how to load the module, define ModuleLoader images for kernel versions, and include instructions for building and signing modules for specific kernel versions. ...

Following on the Using Kcli to prepare for OCM testing, we’re going to prepare KMM testing in Hub-Spoke approach. First we need to prepare our .docker/config.json with the contents of our OpenShift pull secret used with Kcli. mkdir -p ~/.docker/ cp openshift_pull.json ~/.docker/config.json Warning advisories Note Semi-scripted version available at automate.sh Warning We’re using pre-release bits of the software, that’s why we need to define a custom catalog for both the Hub and the Spokes. Once KMM is released it will be available from the official one and just the Policy will be needed. ...
