Hi, Trying to learn Kubernetes by playing around with it. Initially I was using Minikube on my laptop, but then I started looking out for ways to do bit more ambitious things s.a. setup multinode cluster to see how (and how well) high-availability works. Came across` [this (perhaps dated) article](https://www.padok.fr/en/blog/minikube-kubeadm-kind-k3s)` through which I learnt about K3s, which gives this very impressive statement about the minimum config support (of K3s): - ``` Linux 3.10+ ``` - ``` 512 MB of ram per server ``` - ``` 75 MB of ram per node ``` - ``` 200 MB of disk space ``` - ``` x86_64, ARMv7, ARM64 ``` While I did come across mention of min. recommended RAM of 512 MB for servers, but so far not of the 75MB for nodes. Are the above figures still correct ? Where are they mentioned in the documentation ?
