I understand your "Wanna to feel the understanding just by reading a book" well, however it is impossible.
I think that it is difficult to reach the understanding about almost technologies, except for using "Hello World Approach", and as for Docker, I can say "absolutely not"

As I say, the feeling is "Several raspberry PIs whose purposes are different, are screwed into a PC forcedly.
This screwed tech. paradigm makes me light vomiting.

No matter that they are, I hate any book whose title is "Easy XXXX"
