Why docker (feddit.it)

Hi! Question in the title.

I get that its super easy to setup. But its really worthwhile to have something that:

runs everything as root (not many well built images with proper useranagement it seems)
you cannot really know which stuff is in the images: you must trust who built it
lots of mess in the system (mounts, fake networks, rules...)

I always host on bare metal when I can, but sometimes (immich, I look at you!) Seems almost impossible.

I get docker in a work environment, but on self hosted? Is it really worth while? I would like to hear your opinions fellow hosters.

This is a really bad take. I'm all for OSS, but that doesn't mean that there isn't value with things like Docker.

Yes, developers know less about infra. I'd argue that can be a good thing. I don't need my devs to understand VLANs, the nuances of DNS, or any of that. I need them to code, and code well. That's why we have devops/infra people. If my devs to know it? Awesome, but docker and containerization allows them to focus on code and let my ops teams figure out how they want to put it in production.

As for OSS - sure, someone can come along and make an OSS solution. Until then - I don't really care. Same thing with cloud providers. It's all well and good to have opinions about OSS, but when it comes to companies being able to push code quickly and scalably, then yeah I'm hiring the ops team who knows kubernetes and containerization vs someone who's going to spend weeks trying to spin up bare iron machines.
