Thanks for the pointer to Armbian, at the very least its a much more "comfortable" environment than the default friendly setup -- particularly for kernel work. In any case, unfortunately I'm kinda stuck at the same spot -- docker works, kubeadm looks like everything is okay, but the master...

I followed the Lubuntu build your own kernel instructions but applied it to the FriendlyCore image and things seem fine. git clone https://github.com/friendlyarm/kernel-rockchip --depth 1 -b nanopi4-linux-v4.4.y cd kernel-rockchip make ARCH=arm64 nanopi4_linux_defconfig make ARCH=arm64 nanopi4-image...

I've seen references to using the mainline kernel on these boards For example in the wiki: If you are using H3/H5/H2+ series board with mainline kernel, the easier way is using npi-config. Or when I google around it seems like there's some discussion of this in the Armbian threads (https://forum.arm...

Default kernel doesn't have some of the right bits turned on.

I have an alternate config file I'm working on here:

Docker works, but still working on Kubernetes.
