Should I move to Docker? - eviltoast

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?

    Instead of setting up one nginx for multiple sites you run one nginx per site and have the settings for that as part of the site repository.

    Doesn’t that require a lot of resources since you’re running (mysql, nginx, etc.) numerous times (once for each container), instead of once globally?

    Or, per your comment below:

    Since the base image is static, and config is per container, one image can be used to run multiple containers. So if you have a postgres image, you can run many containers on that image. And specify different config for each instance.

    You’d only have two instances of postgres, for example, one for all docker containers and one global/server-wide? Still, that doubles the resources used no?
