Hello! 😀
I want to share my thoughts on docker and maybe discuss about it!
Since some months I started my homelab and as any good "homelabing guy" I absolutely loved using docker. Simple to deploy and everything. Sadly these days my mind is changing... I recently switch to lxc containers to make easier backup and the xperience is pretty great, the only downside is that not every software is available natively outside of docker 🙃
But I switch to have more control too as docker can be difficult to set up some stuff that the devs don't really planned to.
So here's my thoughts and slowly I'm going to leave docker for more old-school way of hosting services. Don't get me wrong docker is awesome in some use cases, the main are that is really portable and simple to deploy no hundreds dependencies, etc. And by this I think I really found how docker could be useful, not for every single homelabing setup, and it's not my case.
Maybe I'm doing something wrong but I let you talk about it in the comments, thx.
Are you using docker compose scripts? Backup should be easy, you have your compose scripts to configure the containers, then the scripts can easily be commited somewhere or backed up.
Data should be volume mounted into the container, and then the host disk can be backed up.
The only app that I've had to fight docker on is Seafile, and even that works quite well now.
Its networking is a bit hard to tweak, but I also dont find I need to most of the time. And when I do, its usually just setting the network to host and calling it done.
