Which is an interesting perspective, considering I've led a platform based on Kubernetes running on company-owned bare-metal. I was actually hired because developers were basically revolting at leaving the cloud because of all the "niceties" they add (in exchange for that hefty cloud tax) which essentially go away on bare-metal. The existing DevOps team was baffled why the developers didn't like when they were handed a plain Ubuntu VM and told to deploy their stack on it.
By the time I left, the developers didn't really know anything about how the underlying infrastructure worked. They wrote their Dockerfiles, a tiny little file to declare their deployment needs, and then they opened a platform webpage to watch the full lifecycle.
If you're a single service shop, then yeah, put Docker Compose on it and run an Ansible playbook via GitHub Actions. Done. But for a larger org moving off cloud to bare-metal, I really couldn't see not having k8s there to help buffer some of the pain.
For many shops, even Docker Compose is not necessary. It is still possible to deploy software directly on a VM/LXC container.
I agree that Kubernetes can help simplify the deployment model for large organizations with a mature DevOps team. It is also a model that many organizations share, and so you can hire for talent already familiar with it. But it's not the only viable deployment model, and it's very possible to build a deployment system that behaves similarly without bringing in Kubernetes. Yes, including automatic preview deployments. This doesn't mean I'm provided a VM and told to figure it out. There are still paved-path deployment patterns.
As a developer, I do need to understand the environment my code runs in, whether it is bare-metal, Kubernetes, Docker Swarm, or a single-node Docker host. It impacts how config is deployed and how services communicate with each other. The fact that developers wrote Dockerfiles is proof that they needed to understand the environment. This is purely a tradeoff (abstracting one system, but now you need to learn a new one.)
