I wonder what the need for tools such as this or other "Kubernetes-by-example" type pages tell us about the complexity of configuring Kubernetes resources. Do we need a better layer of abstraction, i.e. better adoption and tighter integration for something like kustomize? Have we fucked up completely with Kubernetes due to it being outrageously complicated for simple tasks? How we redesign this to be simpler? Is the…

Complexity always exists somewhere. You can't remove it, only try it make it easier to deal with. What Kubernetes allows you to do is very complex so you need a capable system to express it all. YAML isn't always the best but it works fine for most and tools like these are very helpful. Do you use an IDE? Does that mean the language and framework is too complex? No, it's just a tool to help you get things done. More…

Not all complexity is intrinsic, but all complexity incurs a cost.

Needing an IDE to have a reasonable time is a very common criticism against the expressive power of certain languages.

I don't think better abstraction is going to help the underlying problem: there are a lot of questions to answer, and you don't know the answer. Without going into the complexity of Deployments, consider the lowly Pod. What configuration does your app need? What is the name of the container that contains it? How much memory does it use? How much CPU does it need? What ports does it listen on? What HTTP endpoint handl…

In my opinion, Kube's yaml blobs are comparable to binary programs. Complaining that an executable has its settings, paths, ports, memory limits, etc, hard coded inside of it is an obvious code smell.

Tools like Helm solve this problem.

Would be nice to have a linter or something that you know is best practice. Eg if you check your yaml and its more complex than it could be.

There are a number of such tools out there. Here's a short list. I'd be interested in any experiences people have had with them in largish production environments.

what's wrong with googling or copypasting ? toolset (helm template set) with basic blocks is added rather quickly, after that it could be as simple as running helm oneliner with needed variable values in the command line

IMO it needs two things: - a dedicated editor with intelligent autocomplete - stop using YAML, it soon becomes unreadable. JSON is easier to grok.

Isn't YAML supposed to be a superset of JSON? So technically, you should be able to use JSON files right now (barring a few exceptions).

Thanks for the shout-out! We’re trying to be like an “open-Heroku” - back when I worked on OpenStack it was called “the open cloud” and no one knew what we were on about - open stack was enterprise as enterprise gets! Our goal is to make a Heroku-ish platform for getting an app online - but one that doesn’t hold you over a barrel later on. You can even host from a spare home server :) (Disclosure: I’m the CTO)

Do you still expose the k8s bits?

I'm interested in/have previously given up on a product where the control plane is managed for me, I can join the cluster with bare metal nodes, and then it's just Kubernetes.

Agree with this, and would say that often a good way to deal with complexity is encapsulation. I imagine there are some developers that say "why wouldn't you just write it in assembly" Because if you are used to that and write small low level binaries it might work well. But trying to write a larger app it becomes more difficult to reason about.
