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?
Try other container technologies lie LXC or go right side and play with FreeBSD jails. Quality of dockers you can find around is horrendous, giving that Docker itself build for convenience not security. It is not something I will trust.
There’s nothing wrong with OCI Images. If you’re concerned about the security of Docker (which, imo, you should be) there are other container runtimes that don’t have its security tradeoffs (e.g. podman).
Once I got to the point where I was running a ton of containers I’d occasionally have issues where a maintainer wouldn’t resolve issues fast enough for my liking so I started building more containers myself which was a lot easier than I’d anticipated.
