Kubernetes消耗更多内存，为什么？

Question

I have been working with docker to run my scripts on chrome-node and firefox -node and debug with the selenium-hub image where it runs smoothly, but when I use the same with k8s the whole system slows down. Why is this happening, any idea. I am using minikubes for kubernetes and docker toolbox and docker compose for docker.

Thanks,

There would definitely be an additional overhead when you start Kubernetes using minikube locally, compared to just starting a Docker container on the host.

In order to have a Kubernetes cluster, minikube creates a VM on the machine where the Kubernetes components will run in addition to the Docker container.

Anyway, minikube is not a production way for running Kubernetes. It is mostly meant for local development and testing. Therefore, you shouldn't evaluated kubernetes performance based on a minikube installation.
