microk8s v1.18 on Ubuntu 20.04 ``` $ kubectl top node NAME CPU(cores) CPU% MEMORY(bytes) MEMORY% myhostname 1369m 17% 8389Mi 26% ``` Q1. `CPU(cores) = 1369m`, [CPU units](https://kubernetes.io/docs/tasks/configure-pod-container/assign-cpu-resource/#cpu-units) explains that this means 1369milliCPU = 1.369 CPU. Where did this value came from? The physical host has 8 cores (AMD-FX8320), Why did microk8s allocate exactly this value? Q2. `MEMORY(bytes) = 8389Mi`, on which basis microk8s had decided to allocate this amount of RAM to the node? Thanks ---

I do not have a definitive answer on your question (eg the code for ranking CPUs). Just want to point out that these numbers are what Kubernetes detects. These numbers do not look unreasonable. 8 cpu threads of 2012 could be 1.369 threads of a current i7. How much memory does your node have? What do you seen in `free -m` ? ---

> these numbers are what Kubernetes detects. I suppose Kubernetes detects what microk8s had configured the hardware resource to the single-node at installation time. When I installed microk8s 1.18 following the [Quick Start guide](https://microk8s.io/docs/) there were no mention of how the hardware resource should be allocated. I would have given more resource if there was such a possibility. Unless the resources could be allocated to the node dynamically as needed. Is it possible? > What do you seen in `free -m` ? ```auto $ free -m total used free shared buff/cache available Mem: 32139 6992 13060 321 12086 24808 Swap: 7627 99 7528 ``` ---

I am sorry I read this wrong. 8389Mi is the memory used and is 26% of the total memory. 1369 is the CPU milli-units used and is the 17% of the total threads you have. This matches your hardware. MicroK8s does not specify any resources. Kubernetes autodetects the available resources with the help of the metrics-server (`microk8s enable metrics-server`).
