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?
Actually only tried a docker container once tbh. Haven’t put much time into it and was kinda forced to do. So, if I got you right, I do define the container with like nic-setup or ip or ram/cpu/usage and that’s it? And the configuration of the app in the container? is that IN the container or applied “onto it” for easy rebuild-purpose? Right now I just have a ton of (big) backups of all VMs. If I screw up, I’m going back to this morning. Takes like 2 minutes tops. Would I even see a benefit of docker? besides saving much overhead of cours.
