Do I need kubernetes?

Question

Docker

The question is as old as the world, but I would like to ask the experts in view of the lack of practice and experience.
The case is the following, there is a fleet of 9 cars, 6 of them are low-powered 2/4 4/6 and 3 dinosaurs with monoliths for sawing.
It is planned to switch to naturally dockerized microservices.
Is it necessary to try to deploy k8s with such a small number of nodes, or will the question be solved by docker swarm + portainer, with which we already have experience.
In Kuber, the deployment system "drop dockerfile / docker-compose and forget it" attracts, but it scares the entry threshold
Thank you in advance

Someone recently translated an article right for you: https://habr.com/ru/post/585164/

Answer 2

Do I need kubernetes?

Why do you need a fancy truck with a built-in loader, a refrigerator and a tank, if a simple Gazelle is enough for you?
k8s is a tool for specific purposes, with specific requirements.

Kuber is attracted by the "drop dockerfile/docker-compose and forget it" deployment system

Yes, of course, how. Sometimes while you quit, you want to forget.

Answer 3

Not worth it.
It seems to me that a good criterion would be the willingness to hire an individual on Kubernetes. As long as there is no such person, it is not worth switching to him. At the same time, you can gradually prepare your own code for it (Prometheus metrics, running in containers, etc.).
But if you see that you are spending a lot of money on clouds and want to save money by switching to bare-metal (rented or your own), then Kubernetes will come in handy.
I wouldn't use swarm either. Or just systemd-services for containers and some kind of Ansible thread. It will be as reinforced concrete as possible.
