Comment on Why use Proxmox over Podman or Docker?

Docker has its uses, but it has gone to far.
I already have a webserver with Apache, mariadb and everything. Why does your PHP based website only come as a docker solution? Fuck you.
When you go all in with docker, it quickly becomes a mess with rando NICs and containers named “random 32 character string” and dependencies up the wazoo. Ending up running ancient packages because the developer refuses to apt upgrade their shit.
Proxmox or any other hypervisor platform gives you control. Whereas you have to take it for docker and youre still at the mercy or the developers to keep your shit secure.
all the problems you expressed with docker aren’t real problems.
I think you may not like it because you don’t know how to use it.
don’t like how often a maintainer updates their images? build your own.
don’t like having multiple bridge interfaces on your host? configure and manage networks within docker and assign them to your containers.
don’t like having dozens of containers with random names? use docker compose. bonus, you can set up networking with it even easier.
Ending up running ancient packages because the developer refuses to apt upgrade their shit.
Tell me you never really had to deal with dependency hell without telling me. That’s literally the main problem docker solves.

Years ago I’d have one PHP app that required version X of PHP and another that required version Y and my distro often only had one of them (or you couldn’t install both simultaneously), so I’d have to either compile myself (or later use a 3rd party repo). All solvable of course, but then throw in MySQL version requirements and PHP extensions and it’s just extra crap that containers just take care of for you. I’ve had this kind of inter app requirements conflicts with stuff other than PHP, but I’ve had by far more of it with PHP. For a while I used FreeBSD jails to help, but jails was kind of a pain. I enthusiastically embraced docker for PHP stuff early on.
A benefit for application developers, particularly PHP is there’s a lot of differences between distros and how people install and configure PHP. Even like which PHP extensions are available and their settings. Other languages things tend to be more consistent at the system level and customizations are app are usually application level (contrast with PHP extensions and system level configurations). It really helps reduce support issues due to distro/user differences if a developer just provides a working dockerfile as a reference implementation and in my experience this is far more likely with PHP than other languages. I realize this is mostly applicable outside of PHP, but I actually personally see more benefit with PHP based on my past experiences.
