Docker questions

[Morkelon]

Hi all,
I'm trying to install Docker on a Raspberry PI 3 B.
I followed the general steps here:
https://docs.docker.com/install/linux/docker-ce/debian/
and by the time I run the Hello World container, I read that to install Docker Engine in Raspbian you must use the convenience script.
The thing is, after running these commands:
$ sudo apt-get install docker-ce docker-ce-cli containerd.io
$ sudo docker run hello-world

The hello world run fine.

I already uninstall it and I'm going to install it using the convenience script but I wonder:
what's the problem with installing it using the normal way? Since I only run a Hello world container, I want to know what's the explanation about installing it the normal way in Raspbian.
I also want to know why the convenience script works. What's the difference?


Thank you in advance.

Docker provides convenience scripts at get.docker.com and test.docker.com for installing edge and testing versions of Docker Engine - Community into development environments quickly and non-interactively.

You will get newer versions than the one in the Raspbian repository.
