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?
It just making things easier and cleaner. When you remove a container, you know there is no leftover except mounted volumes. I like it.
I use LXC for all the reasons most people use Docker, it’s easy to spin up a new service, there are no leftovers when I remove a service, and everything stays separate. What I really like about LXC though is that you can treat containers like VMs, you start it up, attach and install all your software as if it were a real machine. No extra tech to learn.
It’s also way easier if you need to migrate to another machine for any reason.
