How is it legal to make up a fee then offer a paid membership to avoid the fee you just made up? How is that different from the mob guys that would collect your “insurance” membership so that you didn’t incur a “business burned down” fee?

So far I’ve avoiding learning about Docker by just buying a new old end-of-life Chromebook when I wanted to run anything. Works pretty well, except for the giant pile of Chromebooks behind my TV.

I actually have Portainer set up and running, and I even spun up a few simple containers in it. Unfortunately I did so by following a guide to complete a specific task. I completed the task successfully, but now I have a Portainer install that I don’t understand in the slightest, and don’t know how to update it or any of the containers in it, or really do anything that wasn’t covered in the guide I followed (which I now cannot find). I found a YouTube video that tries to explain Portainer, but I don’t know the terminology of Docker enough to understand what they are saying, and I haven’t found a Docker video simple enough to bring me up to speed.

I think I just need a general overview. Something about the concept isn’t clicking for me, and it makes it hard for me to learn how to use it when I fundamentally don’t get it. Is there a really good “Introduction to Docker and the tools people use with it” that I haven’t found?

Docker is hurting my progress. I just can’t seem to wrap my head around it. Is there a Docker for Dummies?
