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?
Are you familiar with lxc or chroots or bsd jails by any chance? If you are, you probably won’t find docker that much different to use other than a bigger selection of premade images.
It is kind of sad that some projects are trending towards docker first, but I think learning how to make packages for package managers is also becoming less popular :(
Even learning how to do the simplest thing possible that is easy to package by anybody - something like a tarball or zip - is becoming less popular :(
I learned “creating a zip” the hard way when I submitted an exam but forgot the -r on creation, meaning all the to-review code was gone.
