For loading of the out-of-tree sfc kernel module on boot.

For context, please see Out-of-tree sfc kernel module in README and Red Hat documentation: Replacing in-tree modules with out-of-tree modules.

The following steps implement a configuration based on KMM Operator's mcproducer, which is documented in 4.13.5. MCO yaml creation.

An example Butane configuration file is provided (99-sfc-machineconfig.bu) in the format of a template which a convenience script provides variable substitution for your cluster environment.

Two equal methods are provided. Select the one best suited to your terminal environment.

The following requires:

• butane tool in your PATH

Run:

#export OPENSHIFT_VER=4.14.0 # Default is v4.10.0 to 4.13.0
make sfc-mc-build ONLOAD_MODULE_IMAGE=$REGISTRY_BASE/onload-module:$ONLOAD_VERSION-$KERNEL_FULL_VERSION

Docker method

The following requires:

• Docker (or a symbolic link to an API equivalent, e.g. podman) in your $PATH
• Internet access to quay.io to pull the Butane container image

Run:

#export OPENSHIFT_VER=4.14.0 # Default is v4.10.0 to 4.13.0
make sfc-mc-docker-build ONLOAD_MODULE_IMAGE=$REGISTRY_BASE/onload-module:$ONLOAD_VERSION-$KERNEL_FULL_VERSION
