Libre Computer Board ALL-H3-CC

Prerequisites

You will need

• talosctl
• an SD card

Download the latest talosctl.

curl -Lo /usr/local/bin/talosctl https://github.com/siderolabs/talos/releases/download/v1.7.0/talosctl-$(uname -s | tr "[:upper:]" "[:lower:]")-amd64
chmod +x /usr/local/bin/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:

curl -LO https://factory.talos.dev/image/5689d7795f91ac5bf6ccc85093fad8f8b27f6ea9d96a9ac5a059997bffd8ad5c/v1.7.0/metal-arm64.raw.xz
xz -d metal-arm64.raw.xz

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

Upgrading

For example, to upgrade to the latest version of Talos, you can run:

talosctl -n <node IP or DNS name> upgrade --image=factory.talos.dev/installer/5689d7795f91ac5bf6ccc85093fad8f8b27f6ea9d96a9ac5a059997bffd8ad5c:v1.7.0
