Docker - what use is it? - sh.itjust.works

I see Docker mentioned every other thread and was wondering how useful it is for non development things, and if so what they are.

To bloat things, to lower the bar to newcomers, to appease the business goals of large cloud companies and eventually to provide some isolation, security and create stateless environments: lemmy.world/comment/8341439
What's the deal with Docker? - Lemmy.World

I never understood how to use Docker, what makes it so special? I would really like to use it on my Rapsberry Pi 3 Model B+ to ease the setup process of selfhosting different things. I’m currently running these things without Docker: - Mumble server with a Discord bridge and a music bot - Maubot, a plugin-based Matrix bot - FTP server - Two Discord Music bots All of these things are running as systemd services in the background. Should I change this? A lot of the things I’m hosting offer Docker images. It would also be great if someone could give me a quick-start guide for Docker. Thanks in advance!

“The thing with Docker is that people don’t want to learn how to use Linux and are buying into an overhyped solution”

I stopped there. Thirty years of LINUX experience here. You’re a fool.

Just look at landscape around here and other “selfhosting” boards and you’ll see what I’m saying.
I won’t, because I stopped there.
Your choice, you’re the one believing that 100% of the people using Docker are as proficient and you and me and use it the right reasons. Guess what, they don’t.
Are you clairvoyant? I’m curious as to how you are aware of what I believe, beyond what I stated; that you’re a fool.
“how dare they use the right tool for the job without taking the time to learn how to do it sub optimally first”

Your choice, you’re the one believing that 100% of the people… Blah blah blah

Didn’t be shitty. Telling somebody what they believe is shitty. Telling them they believe “100% of people do (anything)” is super shitty. And this whole shitty argument has nothing to do with docker.

Go be shitty elsewhere.
