RHCOS on Exoscale

Prerequisites

• Download the latest RHCOS build for qemu. (e.g: rhcos-4.6.8-x86_64-qemu.x86_64.qcow2) https://mirror.openshift.com/pub/openshift-v4/x86_64/dependencies/rhcos/4.6/4.6.8/rhcos-4.6.8-x86_64-qemu.x86_64.qcow2.gz

• Install guestfish sudo apt install libguestfs-tools.

Modify the RHCOS qcow

gunzip rhcos-4.6.8-x86_64-qemu.x86_64.qcow2.gz

sudo guestfish --rw -a rhcos-4.6.8-x86_64-qemu.x86_64.qcow2

Inside the guestfish shell

><fs> run

><fs> list-filesystems
/dev/sda1: ext4
/dev/sda2: vfat
/dev/sda3: unknown

><fs> mount /dev/sda1 /

><fs> edit /loader/entries/ostree-1-rhcos.conf

A default text editor is opened, inside this file replace ignition.platform.id=qemu by ignition.platform.id=exoscale

><fs> exit

Finally, you can use this Qcow2 as a Custom Template on Exoscale infrastructure.

Enjoy 🚀
