I'm a fullstack engineer that mostly focuses on backend, so yeah, I basically want a copy of our production app running on my work computer. I have Docker configured so it only uses 4GB or so, but when I add our frontend (1-2GB), web browser (1-2GB), Microsoft crap (1-2GB), etc, the RAM adds up, and that's just running half of our backend infrastructure.
The silly thing is that almost all of my job is on Linux services, except our mobile app, which is React native and largely targets iOS (though we also support Android). I work across the stack so I need to be able to run all three (backend, web, and mobile).
But I have to pick and choose what I run because my 16GB system is barely enough. So yeah, I wish we would've gotten 32GB at the outset, because swapping to disk is by far the biggest performance issue.
So yeah, get more memory than you think you need.
I'd appreciate hearing your thoughts about this medium article describing the use of Lima VM for docker on MacOS.
