I like reading declarative docs because everything is spelled out but I hate writing them for the same reasons.

More tooling to write good k8s yaml sounds good to me.

I think of Kubernetes as "the new Operating System", and these complex resources as fiddling with initscripts, fstab, /etc/interfaces, and so on. Writing an operator is like writing your own initscript. I wouldn't be surprised if we eventually see new abstractions for "you just want a plain 'ol deployment with CI/CD du jour, a persistent volume claim, and a service ingress, just like 90% of all other CRUD webapps?

Agreed. Just like how I don't want to roll my own desktop environment on Linux, I will happily accept a good config rollef for me, even if opinionated.

We're using Pulumi https://www.pulumi.com/ to do our K8 configuration. We can use TypeScript interfaces (which give us nice ide code completion) to define our yaml. we can then create functions where we would normally duplicate Yaml. Really nice. https://www.pulumi.com/kubernetes/

> we can then create functions where we would normally duplicate Yaml. This is the way to go for sure. I've done similar by generating CloudFormation from Python (I wrote my own library because I felt Troposphere was not very friendly nor a significant improvement over YAML). Typing turns out to be pretty useful when you're generating YAML. While my library was fully typed, Python's type checking left a lot to be des…

Yes and no.

Typing is a must, but a full-blown programming language is too powerful and all abstraction layers start to leak sooner rather than later. I always ended up with a "deployment" function that exposed almost all underlying functionality.

We're big fans of the Cue (https://cuelang.org) approach instead: https://cuelang.org/docs/about

It's a never-ending cycle. See: Front-end development. Until yet another abstraction emerges, anyone using Kubernetes for mission-critical applications should be using automated testing to prevent awful outcomes from a single botched line of YAML. There are a bunch of solutions emerging in this space, like Datree[0], made for the sole purpose of preventing Kubernetes misconfigurations.

I've always felt that Kubernetes isn't appropriate for most businesses to use directly, but rather it's a platform for simpler platforms--someone like Heroku would build on top of Kubernetes and expose a much simpler interface for their users so they don't have to think about SSL, DNS, logging, load balancing, auto-scaling, etc. Alternatively, maybe the problem is solved with "distributions" of Kubernetes analogous t…

That's exactly what I am doing with https://primcloud.com :)

Well prepare to be unsurprised! The CI/CD abstraction already exists in Tekton - https://cloud.google.com/tekton

The rest are soon to follow I’m sure.

Is it anymore complex than all the old ways? Was Apache, Asterisk, or loading and hardening a Linux host on bare metal easier? I seem to remember a lot of wrangling custom kernels to get Asterisk sounding just right, bizarre Apache, & network configs. It’s just text? It’s always going to turn into a nebulous mess without literal edges and boundaries. That’s Google’s play with it, IMO. Train tracks. Which is what I ha…

There are plenty of online tools to generate Nginx or Vagrant config files.

I don't really get the love for hating on K8 complexity on here - nobody says it's the perfect tool for every use case... but when you do need it, it's amazing, and has many advantages over the current trend for serverless IMO.

Earlier quoted context omitted.

All of the standard Kubernetes resource definitions have a schema [1] [2] which is already used to, for instance, generate Go code [3] and documentation [4]. [1] - https://kubernetes.io/docs/concepts/overview/kubernetes-api/... [2] - https://github.com/kubernetes/kubernetes/blob/release-1.19/a... [3] - https://godoc.org/k8s.io/client-go/kubernetes/typed/core/v1 [4] - https://kubernetes.io/docs/reference/generated/kub…

Of course there is schema at some level, but it feels like it's not utilized. This UI seems like very good use of schema. Another would be if I open up an VSCode, there should be a way to autocomplete / or give error squiggles if I write something wrong, in realtime.

VSCode actually has such a plugin, though it has the hard to discover name “Kubernetes” and is maintained by the little-known “Microsoft”
