On the other hand, my team slapped 3 servers down in a datacenter, had each of them configured in a Proxmox cluster within a few hours. Some 8-10 hours later we had a fully configured kubernetes cluster running within Proxmox VMs, where the VMs and k8s cluster are created and configured using an automation workflow that we have running in GitHub Actions. An hour or two worth of work later we had several deployments running on it and serving requests.

Kubernetes is not simple. In fact it's even more complex than just running an executable with your linux distro's init system. The difference in my mind is that it's more complex for the system maintainer, but less complex for the person deploying workloads to it.

And that's before exploring all the benefits of kubernetes-ecosystem tooling like the Prometheus operator for k8s, or the horizontally scalable Loki deployments, for centrally collecting infrastructure and application metrics, and logs. In my mind, making the most of these kinds of tools, things start to look a bit easier even for the systems maintainers.

Not trying to discount your workplace too much. But I'd wager there's a few people that are maybe not owning up to the fact that it's their first time messing around with kubernetes.

As long as your organisation can cleanly either a) split the responsibility for the platform from the responsibility for the apps that run on it, and fund it properly, or b) do the exact opposite and accommodate all the responsibility for the platform into the app team, I can see it working.

The problems start when you're somewhere between those two points. If you've got a "throw it over the wall to ops" type organisation, it's going to go bad. If you've got an underfunded platform team so the app team has to pick up some of the slack, it's going to go bad. If the app team have to ask permission from the platform team before doing anything interesting, it's going to go bad.

The problem is that a lot of organisations will look at k8s and think it means something it doesn't. If you weren't willing to fund a platform team before k8s, I'd be sceptical that moving to it is going to end well.
