To dockerize an application: where to start learning. (lemmy.ml)

I've recently started a crusade for the perfect selfhosted note taking app.

I posted here and I read a lot of others posts and for now I think I have what I need.

But as I see Joplin recommended every now and then, and given it doesn't offer a webui I can access everywhere from any computer (you need to install their app), I had this thought: how could I dockerize, say, the Linux Joplin app so I can put it behind a reverse proxy with auth and access it when I'm away from home from any computer.

I've seen this done for soulseek, mkvtoolnix and others, so I know it is feasibile.

Being just a hobbyist selfhoster with no programming background, I'm not sure where to start educating myself.

I'm sure there are some guides out there, but I'm not sure what to look for, what terms to use in my searches.

Somebody could point me to the right direction?

Search an issue you have (say ads), research a tool that fits your purpose (pihole) and try to run it in docker.
If you don't understand something, research it.

At leasts that's how I did it.

I think my phrasing wasn't good, or maybe I misunderstand what you say (not a native English speaker), but I know how to run a container. I just want to run an existing app inside a container :)

Learning how to use other Docker images to run Docker containers is an important first step in that process.

I'm a programmer. My foray into learning how to containerize applications started by learning how to run containerized applications. Honestly, running them is the more complicated part (for many cases, some are dead simple).

Turning an app into an image is sometimes just a simple two line Dockerfile.

I started learning with Home Assistant and the branched out to pi hole, Frigate, Mosquito, and other home automation tools. I used that knowledge to containerize a home automation tool I wrote myself.

And now I'm working on containerizing dozens of applications at work.

Thank you, I'll make good use of your advice :)
