Does Kubernetes really need to be as complicated as it is?

pojzon• 7 years ago

As a new person learning Kubernetes I dont really think it is complicated.

If you are familiar with cloud computing and containers, it's pretty straightforward.

But the amount of additional stuff built around Kubernetes - THAT can be overw"helm"ing.

Does his article provide some value the official k8s docs or k8s quickstart tutorial doesn't?

One thing about building deploying and maintain k8s clusters from scratch over the past two years is the noise from these tutorials that effectively repeat the docs to give the author of the medium post street cred to get a better devops jobs, but as far as value add for.devops engineers deploying and dealing with edge cases and mvp case (Lua plugins for rate throttling in ingress controllers for example if you want more control than a gcp load balancer exposing ips to the public for which vpc peering native clusters didn't exist in GCP until late 2018) it is annoying self congratulatory noise that leave new devops engineers stray when they might be better off with the off with the original documentation.

If you have a cool short tutorial on how to iterate on an MVP or solve a security default setting for secure that might be helpful but I rarely see it.

A good example of this is how many articles I saw about how simple it is to share pvcs across an nfs server. 12 "senior level" devops engineers wrote about this and every single one left out the nfs storage class enablement on the gcp platform, a beta security feature presumably some other devops engineer who does more work and received less credit probably enable for them but would leave every devops engineer following their tutorials left stranded.

I used to think I was just a newb devops engineers but when I read devops posts like this I wonder if should just copy and past existing documentation, install some helm tarts via tiller with no rbacs in GUI dashboards enabled, call the data set "AI" and apply for a senior level position.

Sorry to go off on this post but there is no reason to have an 8min intro of the 5min intro on the k8s docs themselves which hyperlink any concept to drill down into with an interactive tutorial in browser that requires no local setup unless you truly desire to use minikube.

I am all for devops tutorials, but useful ones, of which I have barely found any during my two years of teaching myself how to deploy clusters from the ground up.
