Part of installing RancherOS you need to add your public key to a cloud-init file, and that is a lot of keys to type in the VNC terminal that doesn’t allow copy/paste - and you can’t ssh in until this has been done. Catch-22.
Now I see that Proxmox supports Cloud-init, which as far as I understand is what RancherOS uses. There is a ton of reference documentation on it both here https://pve.proxmox.com/wiki/Cloud-Init_Support#_custom_cloud_init_configuration and here https://rancher.com/docs/os/v1.2/en/running-rancheros/server/install-to-disk/ but I’m obviously too thick to glue it all together.
I’m sure it is a matter of providing a short text file with the key, possible ip address etc, and somehow pass that onto Proxmox to do it’s magic and create a RacherOS VM, but how?
Could some kind soul who know please make a short step-by-step of this? That would be so cool!
