Prerequisites

You will need
  • talosctl
  • an SD card
Download the latest talosctl.

​
Download the Image

The default schematic id for “vanilla” Libretech H3 CC H5 is 5689d7795f91ac5bf6ccc85093fad8f8b27f6ea9d96a9ac5a059997bffd8ad5c. Refer to the Image Factory documentation for more information. Download the image and decompress it:

​
Writing the Image

The path to your SD card can be found using fdisk on Linux or diskutil on macOS. In this example, we will assume /dev/mmcblk0. Now dd the image to your SD card: 
sudo dd if=metal-arm64.raw of=/dev/mmcblk0 conv=fsync bs=4M

​
Bootstrapping the Node

Insert the SD card to your board, turn it on and wait for the console to show you the instructions for bootstrapping the node. Create a installer-patch.yaml containing reference to the installer image generated from an overlay: Following the instructions in the console output to connect to the interactive installer: 
talosctl apply-config --insecure --mode=interactive --nodes <node IP or DNS name>
Once the interactive installation is applied, the cluster will form and you can then use kubectl.

​
Retrieve the kubeconfig

Retrieve the admin kubeconfig by running: 
talosctl kubeconfig
