Self-hosting Kubernetes on your Raspberry Pi

  I went into this article with so much skepticism, but yeah, the author addresses all of my concerns. This is a cool project and now I get why you'd do it this way.

  This point I'm not so sure about: Do not buy a multi-charger for the RPi4, they may appear to work, however if you look into things you will find that they are "browning out". Official adapters are not expensive, my advise is not to be stingy. Are they meaning things like this? https://www.amazon.com.au/dp/B07BSBYKDQ https://www.amazon.com.au/dp/B07BSBYKDQ Personally, I've been looking at setting up an RPI4 based cluster and was thinking of getting one of those. Though ideally, I'd probably go with something that can remotely power on/off any given RPI4 eg Shoot The Other Node In The Head (STONITH) for HA and testing, etc. With proper rack servers, we used to use these: https://www.wti.com/products/ips-800-ce-internet-power-switch-dual-10a-240v-8c13 https://www.wti.com/products/ips-800-ce-internet-power-switc...

    I'd recommend getting a PoE switch and put an PoE HAT on each device. Multi-chargers are trouble since they are rarely able to deliver the 5V 3A, unlike the official adapter.

      Interesting thought, thanks. :) Probably don't want to get a new PoE switch, as I have a decent (fanless, silent) 16 port HP Procurve switch already that's barely utilised. PoE switches never seem to be silent, and would annoy me. ;) The other option I've been thinking of, is getting one of those "smart" power control boards + flashing it with Tasmota (https://tasmota.github.io https://tasmota.github.io) firmware. That should work, and allow for using the official RPI4 adapters. :)
