As per usual there is a lot of weird hatred of Docker and K8s on HN. Docker isn't a complex tool and it doesn't take 200 hours to learn enough to be proficient. I have to imagine all of these folks tried to learn Docker 5 years ago and got burnt and refuse to try it again. At its core, you create a Dockerfile which builds on top of a base image. You tell it what files to copy over and which commands to run to get the system in the state you want it. Then you build the image which runs through all those steps and gives you this reusable snapshot. You can create containers using this image locally or you can push it up to a registry and let any of your systems run that exact same service. You absolutely don't have to use Docker, if you're happy using plain VMs why switch? Kubernetes certainly takes longer to learn so I can understand why there is more frustration around it. Though once you learn it, it feels like you've got a super power. Being able to abstract yourself away from the underlying infrastructure is freeing. My co-founder and I originally tried to cut costs by using Terraform + Ansible to provision and maintain all of our infrastructure on basic VMs rather than using Kubernetes which is always more expensive. But we quickly decided it was worth the extra expense to use K8s for all the nice things we get with 0 effort. All that being said, all of us techies get way too in the weeds on all of these things that don't matter. Don't listen to what others are telling you that you need to use. If you prefer to install apps directly on your VMs, keep doing that. If you find Docker gives you a better QoL like it does me, use that instead. All the time you spend on infrastructure work is time that you could be working on new features!
