Setting up fail2ban with nginx proxy manager running via docker

trying to follow this tutorial, i was not able to get fail2ban to work in my setup, so here is a gist in case I forget.

1. install fail2ban

sudo apt install fail2ban

# Resize the file system in UI, under VM -> Hardware -> Click on the disk to resize, click "Resize disk" button

# Confirm increase in disk space (1TB in my case)
$ lsblk
NAME                      MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
