Welcome to the Raspberry Pi Kubernetes home lab series. A bite sized informative guide to help you provision a cluster from scratch.
1. Install Ubuntu on a Raspberry Pi
The Raspberry Pi nodes are provisioned using Ubuntu 22.04 LTS for ARM. Download and unzip the image from the link.
2. Locate the SD card
Diskutil provides information about the formats of disks, which include disk images.
diskutil list
3. Unmount the disk
diskutil unmountDisk /dev/disk2
Unmount the disk so you can write onto it. Note that unmount is not the same as eject. Unmount means to remove the connection to the disk internally; eject means to physically remove it.
4. dd the image into the disk
sudo dd if=<path-to-image>/raspbian.img of=/dev/rdisk2 bs=1m
It is important that you set the block size read/write buffering to optimise the overall time of the task.
5. Enable SSH
touch /Volumes/system-boot/ssh
SSH needs to be enabled so we can talk to the nodes later.
6. Unmount and eject/remove the card
diskutil unmountDisk /dev/disk2
Leave a comment if you have any questions. We will be installing and preparing the nodes next, first manually and then in an automated fashion via Ansible. Happy coding.
