Docker is more than a cop out for than one use case. It's a way for quickly deploy an app irrespective of an environment, so you can scale and rebuild quickly. It fixes a problem that used to be solved by VMs, so in that way it's more efficient.
Well, nope. For example, FreeBSD doesn't support Docker -- I can't run dockerized software "irrespective of environment". It has to be run on one of supported platforms, which I don't use unfortunately.
Well that's where Java comes in /slaps knee
A lack of niche OS compatibility isn't much of a downside. Working on 99.9% of all active OS's is excellent coverage for a skftware suite.
Besides, freebsd has podman support, which is something like 95% cross compatible with docker. You basically do have docker support on freebsd, just harder.
How is POSIX a niche? 🤨
Just POSIX and no other compatibility? Pretty niche, man.
To deploy a docker container to a Windows host you first need to install a Linux virtual machine (via WSL which is using Hyper-V under the hood).
It's basically the same process for FreeBSD (minus the optimizations), right?
Containers still need to match the host OS/architecture they are just sandboxed and layer in their own dependencies separate from the host.
But yeah you can't run them directly. Same for Windows except I guess there are actual windows docker containers that don't require WSL but if people actually use those it'd be news to me.
There's also this cursed thing called Windows containers
Now let me go wash my hands, keyboard and my screen after typing that
Yeah I keep discord in one so that it can't hook my GPU and audio devices.
