I’d guess that about 90% of the webernetes code is ported directly from the Kubernetes codebase. In that sense it is a port of Kubernetes to the browser. But the CRI and CNI are facsimiles created to work in the browser and for the purpose of making educational content.
The thing I think is most misleading about the title is that I haven’t ported _all_ of Kubernetes. It’s just the slice I needed. I’m hoping to gradually port more of it, though.
If someone said they "ported git to the browser" but it was just a UI for git workflows it would be equally misleading.
I think because that isn't what "porting" is.
In such a case I would expect git - the version control code and diffing - running in browser JavaScript in the same way DOOM is when someone says they ported DOOM to the browser.
That's what porting means, right?
Since there are k8s bindings written in languages like Node.js (effectively a port) - and even they don't call it "a port" is worth considering for OP with regards to the title! Just my 2c
I don't think this analogy holds. Version control and diffing are some core capabilities of git. Sam lists core capabilities of k8s that his port can handle: pod lifecycles, container garbage collection, IP allocation, etc.
My understanding is that the interesting part of k8s is how it orchestrates containers, which this port can do a lot of. Your comments imply that a core component of k8s is actually running containers (rather than orchestrating them), but I don't think that's right. That would be the job of containerd or the operating system, depending at what level you're looking at. Happy to be corrected if I'm wrong about any of this!
To call it a port that doesn’t actually work? Idk seems like a baseline requirement.
It’s like saying you ported YouTube to a calculator but it doesn’t play videos because the most interesting part is the search algorithm, and it’s for educational purposes not functionality.
I get your point. I will disagree that it "doesn't work". It does! You just can't use it for real production workloads since it runs in your browser. If you ported kubernetes to your toaster would it be a port? I think so, but you probably couldn't deploy prod on it. That's just a fun semantics conversation though. Is a taco a sandwich? :-)
Considering what kubernetes actually is - there's a fantastic use case if you really did port it to the browser. So when someone says they did it, I kinda expect that they literally ported that containerization logic to JavaScript.
That would mean I could run an image of an OS like Linux in browser JavaScript. It's a wild thing, but that's what porting literally means! And what I expected with that title.
Think of like a PlayStation emulator... the game itself does not need to be ported - just as if you really made a k8s port you would not really need to reinvent Linux in JS, only be able to run it
A PSX emulator can be said to have been ported (e.g. Tomb Raider has been ported to the browser even though it relies on underlying C++) because it ultimately runs fully 1:1 in a web page. It's a port as far as I'm concerned.
But a k8s port that doesn't do what k8s does isn't a port IMO
