Matchbox - customize initrd to include vmtools

[Michael Champagne]

Hi,

I originally posted on CoreOs Dev but did not get any feedback, was maybe not the right place for this question.

I am using tectonic with matchbox for host provisioning. I have installed a 3 host k8s - tectonic cluster with graphical installer (bare metal) and everything is ok.

My hosts are not real bare metal but rather VMs, so I would like to add vm tools to my container linux hosts.

I iused to do that with PXE boot and it work fine.

initrd ./images/coreos/latest/coreos_production_pxe_image.cpio.gz,./images/coreos/latest/vmtools.cpio.gz

I would like to follow same idea with matchbox but so far I was not successfull

Here is the config file without vmtools

{

        "id": "coreos-install",

        "ignition_id": "coreos-install.yaml.tmpl",

        "boot": {

                "kernel": "/assets/coreos/1353.7.0/coreos_production_pxe.vmlinuz",

                "initrd": [

                        "/assets/coreos/1353.7.0/coreos_production_pxe_image.cpio.gz"

                ],

                "args": [

                        "coreos.config.url=http://matchbox.csnet.me:8080/ignition?uuid=${uuid}\u0026mac=${mac:hexhyp}",

                        "coreos.first_boot=yes",

                        "console=tty0",

                        "console=ttyS0"

                ]

        }

}

Where shall I add the vmtool cpio file in the conf file? As a second element of the initrd array or somewhere else in the args section? 

Thanks

Not sure if you have solved this. but I found a solution by adding "-o vmware_raw" in the coreos-install command to install vmtools.
