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.

How is this meaningfully different than using Deb packages? Or building from source without inspecting the build commands? Or even just building from source without auditing the source?

In the end docker files are just instructions for running software to set up other software. Just like every other single shell script or config file in existence since the mid seventies.

I don’t think you understood the context of the comment you replied to. As a reply to “Here are all these drawbacks to Docker vs hosting on bare metal,” it makes perfect sense to point out that the risks are there regardless.

Unless I misread your comment and you’re suggesting that you think devs not having to deal with OS-specific code is a disadvantage of Docker. Or maybe you meant your second paragraph to be directed at OP?

Apparently I was unclear, I was referring to the security implications of using different manifestations of other people’s code. Those are rather similar.

I'd recommend reading up on docker and containerization. It is not a script for setting up software.

I was referring specifically to docker files. Those are almost to the letter scripts for setting up software.

if that's what you're thought is then you really don't understand containerization and I recommend taking some learnings on it.

I find your attitude not just uncharitable, but also rude.
