Logitech Circle 2 Security Webcam has gone Offline (SOLVED)

In November 2022, I realized that my webcam had stopped working. I took it down from above my door mount in order to troubleshoot closely. The unit would power on with a steady white lighting around the front but I was used to seeing green. When I press the button to reset it, it would reboot and start flashing different coloured lights but when I release the button, all lighting would stop.     I looked at Logitech’s support site to find out how to properly reset it. It was simply to hold the button a few seconds until lights start blinking, which is what I have been doing. I had the wired model so I plugged in the unit via USB to my Windows computer to attempt to connect to it. I had a hunch that there was a firmware update that it automatically tried to download and run, and that update caused this. I was right. A few other users on the Logitech forums reported the same symptoms I was experiencing with my Circle 2 webcam. Here was one specific post that I responded to: https://suppo

What Docker Image for GO works on a Raspberry Pi 3 running Kubernetes k3s orchestrator?

I applied and was recently awarded a Cloud-native Application Architecture scholarship by SUSE and Udactity. There were about 12,000 scholars all over the globe who took part in the course made up of 5 lessons in 2 months, with phase 1 ending August 2, 2021. One of the exercises was to run Docker Desktop on my Windows 10 computer and build a docker image alpine:golang which will run a web application and display the infamous Hello World. I uploaded this docker image to my Docker Hub registry for use in a Kubernetes cluster. We needed to install Oracle VirtualBox, Hashicorp Vagrant, and run Kubernetes k3s cluster to host this docker image. This worked well on my computer but I wanted to try the same exercise on my RPi which had a lot less resources and wanted to see how well it worked there. I have a Raspberry Pi 3 running Raspian OS with 32GB of disk and 4GB of memory. I connected the RPi via wifi on my local LAN and have opened up an SSH session to it. First I install
