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?

Learn it first.

I almost exclusively use it with my own Dockerfiles, which gives me the same flexibility I would have by just using VM, with all the benefits of being containerized and reproducible. The exceptions are images of utility stuff, like databases, reverse proxy (I use caddy btw) etc.

Without docker, hosting everything was a mess. After a month I would forget about important things I did, and if I had to do that again, I would need to basically relearn what I found out then.

If you write a Dockerfile, every configuration you did is either reflected by the bash command or adding files from the project directory to the image. You can just look at the Dockerfile and see all the configurations made to base Debian image.

Additionally with docker-compose you can use multiple containers per project with proper networking and DNS resolution between containers by their service names. Quite useful if your project sets up a few different services that communicate with each other.

Thanks to that it's trivial to host multiple projects using for example different PHP versions for each of them.

And I haven't even mentioned yet the best thing about docker - if you're a developer, you can be sure that the app will run exactly the same on your machine and on the server. You can have development versions of images that extend the production image by using Dockerfile stages. You can develop a dev version with full debug/tooling support and then use a clean prod image on the server.
