It's all wildly different for Odroid C4s

1. Do Manjaro ARM to em
2. ansible playbook -i hosts --ask-become-pass kubetime-manjaro-arm

idk about Rock64s, that's a tomorrow problem. CRI-O cuz containerd sucks on these boards, this distro, something. Edits for making CRI-O play nice with CNIs.

Runs cilium, btw.

Provision sdcards

1. dd if=/dev/zero of=/dev/mmcblk0 bs=1M count=32
2. fdisk /dev/mmcblk0 -> o, p, n, p, 1, 32768, enter, w
3. mkfs.ext4 /dev/mmcblk0p1
4. mount /dev/mmcblk0p1 root/
5. bsdtar -xpf ArchLinuxARM-aarch64-latest.tar.gz -C root
6. wget http://os.archlinuxarm.org/os/rockchip/boot/rock64/boot.scr -O root/boot/boot.scr
7. umount root
8. dd if=rksd_loader.img of=/dev/mmcblk0 seek=64 conv=notrunc
9. dd if=u-boot.itb of=/dev/mmcblk0 seek=16384 conv=notrunc

Insert, boot and install minimal requirements for ansible and emergency needs.

pass: alarm

su root
pacman-key --init
pacman-key --populate archlinuxarm
rm /boot/boot.scr
pacman -Sy uboot-rock64 sudo rxvt-unicode-terminfo python

Do wheel stuff

# still as root
sed 's/# %wheel  ALL=(ALL) ALL/%wheel  ALL=(ALL) ALL/' /etc/sudoers

then usermod -aG wheel alarm. You should be able to use sudo now as 'alarm' user.

Set a sane hostname sudo echo 'kubelet-01' > /etc/hostname

Make MAC addresses unique

vi /etc/systemd/network/00-default.link

Match the default MAC showing up on the network, supply a "unique" one instead.

[Match]
MACAddress=da:19:c8:7a:6d:f4

[Link]
MACAddress=da:19:c8:7a:6d:f5
NamePolicy=kernel database onboard slot path

Ansible

install yay on the ansible host

ansible-galaxy install jonsible.yay

vim ~/.ansible/roles/jonsible.yay/tasks/main.yml

#change line 38 to:
state: present

Configure ansible hosts

# /etc/ansible/hosts

[control]
localhost ansible_connection=local

[admin]
kubeadm ansible_user=alarm

[worker]
kubelet-[01:03] ansible_user=alarm

Apply some playbooks...
