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?

I'm not much into new year resolutions, but I think I'll make a conscious effort to learn Docker in the coming months. Any suggestions for good guides for someone coming from VM end will be appreciated.

I learn by twiddling knobs and such and inspecting results, so having come from a tall stack of KVM machines to docker, this helped me become effective with a project I needed to get running quickly: https://training.play-with-docker.com/

You basically log into a remote system which has docker configured, and go through their guide to see what command is needed per action, and also indirectly gets you to grok the conceptual difference between a VM and a container.

Jump straight to the first tutorial: https://training.play-with-docker.com/ops-s1-hello/

Thank you for these links, they look just right. Most tutorials I come across these days are videos. Maybe they are easier to make. These tutorials that allow you to tinker at your own pace seem better to me. Will you mind if I reach out to you over DM if I get stuck at something while learning and am not able to find the right answer easily?

Sure, that's ok. Thanks for asking.

The networking send to be where documentation for both docker and podman seem to be a bit slim, just a heads up.
