  • installer

    Install an OpenShift 4.x cluster (by openshift)

    • Not sure if this will work but I noticed that openshift-installer can be built with libvirt support so the assumption could be made that the platform would support customization like others. Using the oVirt platform docs as a guide you could try:

  • cluster-api-provider-libvirt

    • I don't think there are any docs for the libvirt provider yet, but have a look through. I had a look through https://github.com/openshift/cluster-api-provider-libvirt/blob/master/examples/ but none of the machine or machineset examples in there seem to specify the disk size... based on the api definitions I recon the correct field to set in your machineset is .spec.template.spec.providerSpec.value.volume.volumeSize.

  • snc

    Single Node Cluster creation scripts for OpenShift 4.x as used by CodeReady Containers

    • You can use something like https://github.com/code-ready/snc/blob/master/snc.sh#L135-L139 before installation.
