That’s really what I’m doing on my debian server where I host my docker containers.
I don’t care if I brick my system while playing arround because every day at 00:00 a crontab job dumps all my database and saves all my docker volumes and docker-compose to an external HD and saves most important dotfiles and wireguard configuration.
Back Up and running in 30 min !
2 years in, still going strong and learning everyday something new, keeping everything I learn in a markdown file.
Personal CA with self-signed certificate by an intermediate CA chain
Wireguard tunnel routing all my devices traffic to protonVPN
Alot of docker stuff
Alot of networking stuff (DNS, cryptography…)
LVM, bash…
…
Wild ride, sometimes alot of frustration, but what an empowering experience !
