I see this too and it worries me. You should rarely have to do this. CRDs tend to get overused. I'd encourage everyone to think twice before adding a custom controller. Vanilla k8s (with cloud-provider integration) is powerful, useful, and complex as it is.

because once you know how k8s works, you gain so much time and have to deal with much less low-value problems.. I couldn't go back to the old way

totally agree :) I have been running Kubernetes in production for several years now on multiple projects. So far I had no need to use any CRDs or even Helm. Just well maintained deployments, services, secrets and ingress manifests.

That push towards growth is real across both sides of the developer-administrator spectrum (I know many experienced developers struggling through React/Vue, ETL pipeline tools, or more devops than they'd prefer).

Across the board, it's partially fad and hype, but it's also because these workflows really are better. On the k8s side, a containerized architecture gives developers peace of mind in their local environments, makes you more provider-agnostic, and has the potential to scale more easily.

A sysadmin who can provide all of those is valuable, and deciding if that value is worth the learning curve is an individual decision. But to whatever extent the "resume-driven-development" aspect of container orchestration hype is distorting the market, it does seem to be in service of a better (if more complicated) toolset.

...unless you use cloud-specific services, which almost everybody should be doing because the management load of self-hosted alternatives is very high. Correctly care-and-feeding a message queue or a log store is so much more work than creating an SQS queue or a Kinesis shard, especially when you are not running a company centered around managing a message queue or a log store. Which you probably aren't. Localstack exists as an AWS stub for local development, but it sure isn't great and the impedance mismatch is pretty high--just trying to write Pulumi code that can target either it or AWS proper is an exercise in frustration.

Don't get me wrong: containers as a better way to ship "statically linked" applications are great. But none of the container-orchestration stuff seems out of the "hype" stage from anything I've seen as a consultant or as a line developer; I've never-not-once found a reason to reach for k8s on any major cloud provider. I guess it's OpenStack 2.0 for on-premises deployments, and in that light there's definitely some value, but your cloud provider is doing a lot of work that you're already effectively paying for by being in that ecosystem--for most users (who can't hire somebody like me) it's worth using it.
