Docker runs in a VM on MacOS anyway, it’s not running on bare metal. Is instruction-set even relevant in that world?

That uses hardware virtualization which is very much dependent on the architecture. Running an x86 docker image on a M1 would take a significant performance penalty.

Thank you for posting this! I was so confused when folks were saying 16GB of ram was too little.

I run Linux on all my machines, and even running many (5-10) containers, 16GB was plenty. I now understand a bit better.

My Linux laptop locks up every now and then with swapping when I'm running our app in k3s; three database servers (2 mysql, 1 clickhouse), 4 JVMs, node, rails, IntelliJ, Chrome, Firefox and Slack, and you're starting to hit the buffers. I was contemplating adding more ram; 64 GB looks appealing.

I would not buy a new machine today for work with less than 32 GB.
