I am trying to get some data points on how many containers we can run on a single host if all the containers run the same applications (eg: Wordpress w/nginx, php-fpm, mysql). We have a number of LXD 2.0 servers running on Ubuntu 16.04 - each server has 5G RAM, 20G Swap, and 4 CPUs.
I have read about Kernel Samepage Memory (KSM), and it seems to be included in the Ubuntu 16.40 kernel. So, in theory, we can over provision our containers by using KSM.
