Should I move to Docker? (lemmy.ca)

I'm a retired Unix admin. It was my job from the early '90s until the mid '10s. I've kept somewhat current ever since by running various machines at home. So far I've managed to avoid using Docker at home even though I have a decent understanding of how it works - I stopped being a sysadmin in the mid '10s, I still worked for a technology company and did plenty of "interesting" reading and training.

It seems that more and more stuff that I want to run at home is being delivered as Docker-first and I have to really go out of my way to find a non-Docker install.

I'm thinking it's no longer a fad and I should invest some time getting comfortable with it?

Oh, I thought you had multiple machines.

I use docker because each service I use requires different libraries with different versions. With containers, that doesn't matter. It also provides some rudimentary security. If an attacker gets in, they'll have to break out of the container first to get at the rest of the system. Each container can run with a different user, so even if they do get out of the container, at worst they'll be able to destroy the data they have access to - well, they'll still see other stuff in the network, but I think it's better than being straight pwned.
