K8s and Docker are purely Linux things. Use Linux for that. Its like you would say "I really like these Jails, on which Linux distribution I can run them on?" :) On FreeBSD You use Jails and Bhyve.

Which I happen to know. But it was an example. If I am going to switch to FreeBSD it has to run the software I need, not to merely provide alternatives. And it has to do it better.
Saying that FreeBSD has jails as an alternative is akin to saying Linux has Gimp as an alternative to Photoshop. Not many are going to switch operating systems to use Gimp instead of Photoshop.
As for the usage ... FreeBSD Jails can have their OWN network stack (with own firewall and interfaces) while Docker can only use Linux network namespaces.
You can launch/start a single process Jail and a single process Docker - here they are similar. You can also unpack entire operating system userland in both and it will also run - with own packages database etc.
Hope that helps.
Then it become natural for teams to share dockerfiles as way for sharing environment setups in all the same way.
Using `docker run something` requires zero to none knowledge of the OS, Networks (nat included), packages. Everything will be auto downloaded.
Compare to jails.
That way I get a coherent well configured system everywhere.
They want be in control of their API, but not boring sysadmins stuff.
Jails are targeting sysadmins, thus Docker wins the adoption.
Like cars with manual transmission.
> But the manual transmission is dying out. Just 41 out of the 327 new car models sold in the United States in 2020, or 13%, are offered with a manual transmission, according to data from Edmunds. That is a tremendous drop from less than a decade ago. In 2011, 37% percent came with manuals.
But since I am in charge of the control loop, I can change it any time I please. Right now I am changing my poudriere configuration for the first time in years to build my packages using LibreSSL instead of OpenSSL. Sure, it requires some tinkering(not alot though) but that tinkering is completely optional on my part.
Yet I have practical question for every Jails user, especially when I see "I did..." statements, like in yours:
>The way I have configured poudriere/pkg
How it works for _team_, how it works for "we", where common ground is expected. I have seen teams of 5-10 using Docker as base ground for their dev (local laptops with Windows, MacOS,Linux)/stage/prod envs, but I have not heard on any of such kind with Jails over last 10 years. I hardly can imagine that without forcing everyone to switch to FreeBSD as daily driver. Can you share experience of your team?
Just like with your Photoshop (or Lightroom) example - if you need to run one - you use macOS or Windows for that - Linux also not possible here.
Correct, K8s and Docker will only work one single platform, namely Linux and Windows. No, wait, that's two. K8s and Docker can only possibly run on these two platforms: Linux, Windows and macOS. Ok, let me start over. The three platforms that support K8s and Docker are Linux, Windows, macOS and Oracle Solaris[1]. That's not... ok, the FOUR and ONLY four platforms that can run K8s and Docker are Linux, Windows, macOS, Illumos[2], Solaris, SmartOS, and FreeBSD.[3] How many did I say?
K8s and Docker run anywhere someone is driven to make them run.

macOS Docker performance leaves much to be desired, but this is moving goal posts and suggestive of infinite ignorance: nothing other than Docker on Linux is acceptable. But Docker is just software and it will work wherever, and it has its limitations and plenty of competition to do what it doesn't do or does poorly. Die on the Docker Linux hill if you wish, but, last I checked, platform agnostics are versatile, more marketable, and more valuable, while penguinistas have become all too common. "Give me Philips head screwdrivers or give me death! How can you still use flathead drivers? Or star bit drivers? LOL You're not even screwing seriously. Real men use Phillips." Same thing, really. When you need tools to work, you'll take care of them. But precious few, if any, actually worship them.
