Friendlyelec Nano PI R4S

Installing Talos on a Nano PI R4S SBC using raw disk image.


You will need

  • talosctl
  • an SD card

Download the latest talosctl.

curl -Lo /usr/local/bin/talosctl$(uname -s | tr "[:upper:]" "[:lower:]")-amd64
chmod +x /usr/local/bin/talosctl

Download the Image

The default schematic id for “vanilla” NanoPi R4S is 5f74a09891d5830f0b36158d3d9ea3b1c9cc019848ace08ff63ba255e38c8da4. Refer to the Image Factory documentation for more information.

Download the image and decompress it:

curl -LO
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. 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


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

talosctl -n <node IP or DNS name> upgrade
