I was just about to set up Firefly in Docker... but I'm hesitant due to too many constraints, any of which would leave my data somewhat stranded. Here's my thinking.
• Developer dependent... this is a "smallish" project and should the developer tire of his hobby, or be pulled away due to life's circumstances, I'd be facing a dead end street.
• NAS dependent... As long as I have a compatible server running without disruption, things are fine. Should my NAS fail, I'm dead in the water without a parallel system to run from. With no Windows/Linux system, harboring my financial data on a self-hosted server alone is unattractive to me.
The second point concerns me the most. I'm just not that confident in Synology to continue down this road. Docker is barely supported, and in my case, a
DS418play, I'm a bit of a renegade running Docker... and halfway expect that Synology will update DSM in a manner that blocks Docker usage entirely from my unit.
While MoneyManagerEX seems dead in the water (bullet point one, above) I have 2 PCs capable of managing my data, and in the worst case, compatibility with LibreOffice (or other) spreadsheet programs... so I will continue to muddle through with that program.
I migrated away from Synology Notes due to its dependence on Synology software and hardware, and after thinking things through, I think I'll backburner Firefly for the time being.
