In this lab you will review the machine requirements necessary to follow this tutorial.
This tutorial requires four (4) virtual or physical ARM64 machines running Debian 12 (bookworm). The follow table list the four machines and thier CPU, memory, and storage requirements.
| Name | Description | CPU | RAM | Storage |
|---|---|---|---|---|
| jumpbox | Administration host | 1 | 512MB | 10GB |
| server | Kubernetes server | 1 | 2GB | 20GB |
| node-0 | Kubernetes worker node | 1 | 2GB | 20GB |
| node-1 | Kubernetes worker node | 1 | 2GB | 20GB |
How you provision the machines is up to you, the only requirement is that each machine meet the above system requirements including the machine specs and OS version. Once you have all four machine provisioned, verify the system requirements by running the uname command on each machine:
uname -movAfter running the uname command you should see the following output:
#1 SMP Debian 6.1.55-1 (2023-09-29) aarch64 GNU/Linux
You maybe surprised to see aarch64 here, but that is the official name for the Arm Architecture 64-bit instruction set. You will often see arm64 used by Apple, and the maintainers of the Linux kernel, when referring to support for aarch64. This tutorial will use arm64 consistently throughout to avoid confusion.
