Radxa ROCK 4C Plus

Prerequisites

You will need

• talosctl
• an SD card or an eMMC or USB drive or an nVME drive

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

Download the Image

The default schematic id for “vanilla” Rock 4c Plus is ed7091ab924ef1406dadc4623c90f245868f03d262764ddc2c22c8a19eb37c1c. Refer to the Image Factory documentation for more information.

Download the image and decompress it:

curl -LO https://factory.talos.dev/image/ed7091ab924ef1406dadc4623c90f245868f03d262764ddc2c22c8a19eb37c1c/v1.7.0/metal-arm64.raw.xz
xz -d metal-arm64.raw.xz

Writing the Image

The path to your SD card/eMMC/USB/nVME 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

The user has two options to proceed:

• booting from a SD card or eMMC

Booting from SD card or eMMC

Insert the SD card into the board, turn it on and proceed to bootstrapping the node.

Bootstrapping the Node

Wait for the console to show you the instructions for bootstrapping the node. 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/ed7091ab924ef1406dadc4623c90f245868f03d262764ddc2c22c8a19eb37c1c:v1.7.0
