This article provides a detailed guide on netbooting an Orange Pi Zero 3 with Armbian using a root filesystem over NFS. The author explains the setup process, including configuring the SPI and u-boot, setting up TFTP and NFS servers, and preparing the root filesystem over NFS. The purpose of netbooting is to experiment with Kubernetes on a cluster of Single Board Computers (SBCs) without wearing out the Micro SD cards. The article also mentions the use of a Power over Ethernet switch to power the SBCs and the importance of having a static IP address for the Orange Pi 3. Additionally, it covers updating u-boot environment variables to enable successful PXE booting and provides instructions for creating configuration files for TFTP. The guide emphasizes the need for console access via UART or HDMI during the setup process.
