Here is a link to the firefly-iii website installation instructions. You can install the csv-importer into the same container as firefly, but the only way I know how to get this to work with the single IP address of the container is to either run csv-importer in a sub directory e.g. 192.168.1.128/cs, which isn't necessarily trivial, or run your own local DNS server (which I tried and seemed to work ok).  Instead, I created a seperate container just for the csv-importer. I did this by cloneing the firefly container which already had the LEMP stack installed and everything, and then installed the csv-importer in that container and updated the nginx config to point to the correct root path. To begin, first read through the official documentation so that you hav an idea of whats going on

Container

First, create a 20.04 privileged container with 1 core,  512 mb ram, and default 8GB hard disk space, or **clone the firefly contain

This is a summarized guide I created while installing Firefly-III in a Proxmox (6.2-15) container running Ubuntu 20.04.

I followed this tutorial. It has a link to this other tutorial for installing mariaDB. Furthermore, the official Firefly-iii documentation is Here . 

This guide has everything I did in one concise summary. Not much is explained. This will take about 1.5 hrs.

Note: I initially followed the official instructions and used a LAMP stack. I had issues with apache and getting the webserver to work (likely because I am not familiar with apache and am more comfortable with nginx).
