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?

Apart from the dependency stuff, what you need to migrate when you use docker-compose is just a text file and the volumes that hold the data. No full VMs that contain entire systems because all that stuff is just recreated automatically in seconds on the new machine.

Ok, that does save a lot of overhead and space. Does it impact performance compared to a vm?

If anything, containers are less resource intensive than VMs.

Thank you. Guess i really need to take some time to get into it. Just never saw a real reason.

The great thing about containers is that you don't have to understand the full scope of how they work in order to use them.

You can start with learning how to use docker-compose to get a set of applications running, and once you understand that (which is relatively easy) then go a layer deeper and learn how to customize a container, then how to build your own container from the ground up and/or containerize an application that doesn't ship its own images.

But you don't need to understand that stuff to make full use of them, just like you don't need to understand how your distribution builds an rpm or deb package. You can stop whenever your curiosity runs out.

Won't need to containerize my own stuff. Yet. But many apps just give a recent docker or some outdated manual install stuff. Hence why i get more and more annoyed/intrigued by docker 😁

Thanks for the guide!
