Hetzner cloud userdata

[Kenzim]

Hi,

I followed the tutorial on how to make a cluster on Hetzner cloud - I had the Talos iso uploaded to my project, and then booted the control plane servers and workers using that. I loaded the configuration YAML files into the user data for the servers like the tutorial shows, but the servers didn't seem to pick it up. I had to manually apply the configuration to the servers, but this as far as I am aware is temporary and the config is stored in memory. Is there anything I have to do to make it read the config from Hetzner's user data provider? Any help would be appreciated.

Thanks

Hello, ISO(CD) version uses metal platform by default. You can switch it in grub menu at boot time

talos.platform=hcloud

Second way is create a VM and make snapshot. And use this snapshot to bootstrap new VMs.

Third - use the hashicorp packer https://www.talos.dev/docs/v0.14/cloud-platforms/hetzner/#packer

Thanks for the quick answer. So I could change the platform in the ISO and then use that instead?

Thanks

Easiest way is snapshot.

ISO: You need to rebuild iso image, and change the /grub/grub.cfg
It looks like:

menuentry "Talos ISO" {
	set gfxmode=auto
	set gfxpayload=text
	linux /boot/vmlinuz init_on_alloc=1 slab_nomerge pti=on panic=0 consoleblank=0 printk.devkmsg=on earlyprintk=ttyS0 console=tty0 console=ttyS0 talos.platform=metal
	initrd /boot/initramfs.xz

you need to change talos.platform=metal -> talos.platform=hcloud

At boot time, you can put e key and edit the menu too.
