Based on https://www.flamingbytes.com/blog/cgroups-limit-memory/

Install prerequisites:
  $ apt install libcgroup libcgroup-tools

Create new group:
  $ cgcreate -g memory:/memlimited

Set limit:
  $ echo 32G > /sys/fs/cgroup/memory/memlimited/memory.limit_in_bytes
  $ cgset -r memory.limit_in_bytes=32G memlimited 
  
Limit usage for current shell and subprocesses:
  $ echo $$ > /sys/fs/cgroup/memory/memlimited/tasks
