How to start K3S on Raspberry Pi3
Step-by-step guide to installing and running K3S on a Raspberry Pi 3, including cgroup configuration and Helm installation.
Reference: https://blog.alexellis.io/test-drive-k3s-on-raspberry-pi/
Before installing K3S, you need to enable 64-bit mode and cgroups on the Raspberry Pi. Verify the arm_64bit setting in /boot/config.txt and add the required cgroup kernel parameters to /boot/cmdline.txt. After rebooting, set environment variables to configure kubeconfig permissions and disable unnecessary components, then run the K3S installer. Finally, install Helm for managing Kubernetes packages.
