Ingress-nginx on ARMv7 Raspberry Pi 3 Model B

https://github.com/kubernetes/ingress-nginx

Note after Installation Guide:

1. User Metallb as load balancer on bare metal for K8S on Raspberry 3.0B
2. In the mandatory.yaml file, change container image into:quay.io/kubernetes-ingress-controller/nginx-ingress-controller-arm:0.30.0 (thanks alexellis on github)
3. In the cloud-generic.yaml remove line:externalTrafficPolicy: Local. Kubernetes default externalTrafficPolicy is: Cluster. (It matters if Weave Net is used for networking)
4. kubectl create -f mandatory.yaml -f cloud-generic.yaml (one liner, so nginx-ingress-controller would not complain non-existence of service:ingress-nginx, which gets an IP address assigned from Metallb.
5. check logs inside nginx-ingress-controller for readiness or other errors if any.

I tried Helm 3 without luck. It seems there is repo issue.

VNC headless mode on Raspberry Pi low remote desktop resolution

Connecting to Raspberry Pi without keyboard and monitor connected via VNC viewer, but default display resolution is 640x480, which is too small and could not be scaled up.

After google for a while, link below provide the solution to change VNC screen solution:

https://www.realvnc.com/en/connect/docs/raspberry-pi.html

The term is headless and  To change the resolution, run the command sudo raspi-config, navigate to Advanced Options > Resolution, and choose an option. HDMI mode: Force

Thanks realvnc, and I learned something new.

Raspberry Pi 3B no video output

New Raspberry Pi 3B from MicroCenter, connected to TV via HDMI connection but there is no video signal on the screen.

Got a replaced Pi from MicroCenter again, and there is still no video signal, then I realized there is something else wrong, other than just bad video output.

Looking back to instruction guide, it mentions that using keyboard to type 1 or 0 depend on video cable connection, then I realized that initial NOOB boot needs keyboard!

Once I got keyboard connected, boot screen show up on TV right away.

After Raspbian OS is installed successfully, you can boot it without keyboard and monitor.

Sorry, MicroCenter.
