> How do you update the software in the containers when new versions come out or vulnerabilities are actively being exploited?

You build new image with updated/patched versions of packages and then replace your vulnerable container with a new one, created from new image

Am I the only one surprised that this is a serious discussion in 2025?

[AdrianB1]

Perhaps. There are many people, even in the IT industry, that don't deal with containers at all; think about the Windows apps, games, embedded stuff, etc. Containers are a niche in the grand scheme of things, not the vast majority like some people assume.

[teekert]

Really? I'm a biologist, just do some self hosting as a hobby, and need a lot of FOSS software for work. I have experienced containers as nothing other than pervasive. I guess my surprise is just stemming from the fact that I, a non CS person even knows containers and see them as almost unavoidable. But what you say sounds logical.

I'm a career IT guy who supports biz in my metro area. I've never used docker nor run into it with any of my customers vendors. My current clients are Windows shops across med, pharma, web retail and brick/mortar retail. Virtualization here is hyper-v.

And it this isn't a non-FOSS world. BSD powers firewalls and NAS. About a third of the VMs under my care are *nix.

And as curious as some might be at the lack of dockerism in my world, I'm equally confounded at the lack of compartmentalization in their browsing - using just one browser and that one w/o containers. Why on Earth do folks at this technical level let their internet instances constantly sniff at each other?

But we live where we live.

Self-hosting and bioinformatics are both great use cases for containers, because you want "just let me run this software somebody else wrote," without caring what language it's in, or looking for rpms, etc etc.

If you're e.g: a Java shop, your company already has a deployment strategy for everything you write, so there's not as much pressure to deploy arbitrary things into production.

The world is too complex, and life paths too varied, to reliably assume "everyone" in a community or group knows about some fact.

You're usually deep within a social bubble of some sort if you find yourself assuming otherwise.
