Serving a website on a Raspberry Pi Zero running in RAM (opens in new tab)

So while the content is in RAM on the Pi, a lot of the heavier lifting (TLS termination) is done elsewhere, which saves a ton of CPU load on the Pi.

I found a fun bug with it a couple years ago: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/lin...

It is still able to build software faster than it is released. It takes roughly a month to recompile the entire system :D

for the ones that say that the pi can't handle tls that's just stupid. that's trivial as well.

for the ones saying that you need a vps how cloud native are you people? you can just expose a port on your router (if you're brave enough) and have any dynamic dns service point to the correct ip address.

A Pi with Ethernet can truly boot diskless via TFTP. And later Pi4 and Pi5 can even boot directly from the internet by getting their initial "boot.img" FAT partition via HTTP from anywhere. That would be diskless.

I run my micro-homelab on a Pi Zero from 2018. It’s behind Cloudflare tunnels. It runs the apps i need on a DietPi OS within 180MB and it’s uptime is ~8 months.

And then that Its newer RAM is even several <more> orders of magnitude faster[-than-new.SSD]

I now run a fulltime MacPro6,1 – with dozens of gigabytes of RAMdisk – as an integrated swapdisk on my localnetwork.

I don't mean to shit on this, exploration is nice and putting perfectly fitting hardware to use instead of throwing abundant unnecessary hardware on every simple problem — just to bring it to crawl with loads of shitty bloates software — is good, but it's not particularly impressive.

A Raspberry Pi Zero can just run apache.

For whatever reason, the speed seems far faster than Python for me.

- R-Pi Zero W

- Sixfab UPS hat

- Sixfab Cellular IoT App Shield

- R-Pi model 1B

With all this I should be able to make a multiply redundant always-on bastion host. It's awesome that alpine supports the armhf stuff, many OSes have dropped 32bit support entirely.
