Dear God yes. It makes life a lot easier. It's very easy to use and understand.
I have a feeling that once you've used it you'll be kicking yourself for not doing so sooner.

I am a network engineer and I am learning it. I see it in the next step from the bare metal -> virtualisation evolution
It's basically a vm without the drawbacks of a vm, why would you not? It's hecking awesome
There are teachings I have read/ discovered through YouTube (can't remember exactly where) about the reasons and the philosophy behind moving to docker, or having it as a state machine.
Have you considered looking into dockers alternatives, also ?
Here is 1 of the sources that may give you insights:
https://www.cloudzero.com/blog/docker-alternatives/
-- There has been some concerns over docker's licensing and, as such, some people have started preferring solutions such as podman and containerd.
Both are good in terms of compatibility and usability, however I have not used them extensively.
Nonetheless, I am currently using docker for my own hyperserver [Edit2: oops, I meant hypervisor ✓, not hyperserver] purposes. And I am also a little concerned about the future of docker, and would consider changing sometime in the future.
[Edit1: I am using docker because it is easy to make custom machines, with all files configurations, and deploy them that way. It is a time saver. But performance wise, I would not recommend it for major machines that contain major machine processes and services. And that's just the gist of it].
i use it for gitea, nextcloud, redis, postgres, and a few rest servers and love it!, super easy
it can suck for things like homelab stablediffusion and things that require gpu or other hardware.
postgres
I never use it for databases. I find I don't gain much from containerizing it, because the interesting and difficult bits of customizing and tayloring a database to your needs are on the data file system or in kernel parameters, not in the database binaries themselves. On most distributions it's trivial to install the binaries for postgres/mariadb or whatnot.
Databases are usually fairly resource intensive too, so you'd want a separate VM for it anyway.
Very good points.
In my case I just need to for a couple users with maybe a few dozen transactions a day; it's far from being a bottleneck and there's little point in optimizing it further.
Containerizing it also has the benefit of boiling all installation and configuration into one very convenient dockercompose file... Actually two. I use one with all the config stuff that's published to gitea and one that has sensitive data.

Why would you try avoiding it if you understand how it works? It has so many upsides and so few downsides. About the only practical one is using more disk space. It was groundbreaking technology in 2013. Today it's an old and essential tool.
