Sometime I feelt hat k8s make me frustrated, Latest time I wrote this document is 4 years ago, that’s old version, but when I want to use k8s as container manager again, seems that something different and network won’t work, original document cannot work anymore, it needs to have new document to record that.

My hardware also different, if you don’t have such powerful machine, it can skip numa part, that’s only for high end ARM64 machine.
The hardware is Ampere Mt. Collins which has 2*Ampere Altra 80 Cores CPU and 8*32G Memory, my experiment is run different VM on different CPU, to seperate them and lock it on different numa node.
