You don't have to know how it works in order to use it. I don't know either but I could host services using docker. trust me it's way easier than it seems.

Docker, how they work?

I've been using linux on and off for 20 years and docker reignited my interest for running linux. There's plenty of good guides and free courses, if you need help finding one - let me know and I'll send you a YT playlist.

How to docker-compose in thirty seconds.

Simply make a file called

compose.yaml

Then paste in the text from your application's docker-compose instructions.

Often the timezone needs to be set, along with the volume

Example:

volume: /mnt/hdd/data:/data

This means the application's data directory will be mounted at /mnt/hdd/data

Then

docker compose up -d

You're done, that's all there is.

docker-compose is fantastic because in a single compose.yaml file you can list multiple services.

For example, my compose.yaml file contains my sonarr/radarr/bazarr/lidarr/prowlarr/qbittorrent/deemix/jellyfish/jellyseerr

And I can update them all by running a shell script made of three lines.

Docker compose is amazing. I don't even know how many things I'm running right now. Hell I'm running things I didn't even use! (I could easily disable or delete them; I'm just lazy)
