	1.Add “aufs” or “overlay” (or both) to /etc/modules-load.d/modules.conf in your PVE host and reboot. Check it with lsmod \| grep -E 'overlay\|aufs'
	2.Use a LXC image with unprivilege features (you can check them here: https://uk.images.linuxcontainers.org/)
	3.Create the container with unprivilege option, and “keyctl=1, nesting=1” features (Options section in proxmox).
	4.Maybe you would want to mount an external point into /var/lib/docker (Resources section in proxmox)
	5.Check this link (https://docs.docker.com/storage/storagedriver/overlayfs-driver/#configure-docker-with-the-overlay-or-overlay2-storage-driver) to change your storage-driver in docker to use aufs or overlay2.
	6.Install portainer: https://portainer.readthedocs.io/en/latest/deployment.html

	I turned runCommand into a polymorphic function and

	# The following changes proved to be necessary to make it work on CentOS 7:
	# * removed disk info (model, size) - not very useful, might not work in many cases.
	# * using "bw" instead of "bw_bytes" to support fio version 3.1 (those availible through yum @base)
	# * escaping exclamation mark in sed command
	# * the ".fiomark.txt" is not auto-removed

	# This server demo does a socket hijack in Rack and then saves the socket to a global variable
	# to prevent it from being GCed when the Puma thread ends. It will then write "BEEP" to each
	# socket every ten seconds to prevent the connection timing out. During testing, it easily
	# handled up to 65523 connections, after which it ran into the `ulimit` for open file descriptors.
	# The bit with the waiting area is there because a normal `Set` is not thread safe and it would
	# drop socket due to race conditions. The `Queue` is thread safe and will make sure all sockets
	# are preserved.

	# run with `rackup -q -p 8000 -o 0.0.0.0 c10k.ru`
	# testing: install `ab` and then run `ab -c 20000 -n 20000 <ip adress of server>:8000/
