In the case of docker I’m already at the point where I no longer think it’s necessary. At my current job our stack is JS, PHP and Python. 3 interpreted languages, we then build on Ubuntu and deploy on Ubuntu. I don’t think our project really needs docker, even though it does use it. We also have wasm/wasi prepping to eat Docker’s lunch.
The performance is just a “nice to have”.
Python package management, especially at scale is infuriating. At work we use python microservices in docker containers and it infuriates me trying to update the one our team is responsible for.
I always like to rant that python 3rd party package management tools are a mistake. We should’ve gone for an “as simple as possible” setup instead of all this.
So I’m sceptical of UV on principle since it’s yet another 3rd party package manager but if it can do all of this and not be a nightmare I’ll be ok with it.
