After reading the linked article, I feel that this response “answers” the question without giving any information that satisfies the question.
There’s a joke about how a guy in a balloon has drifted off-course and he yells down to a person on the ground, “where am I?” and the person replies, “in a balloon”. It’s a correct answer but it’s not helpful. The linked article is similarly only partially useful regarding the OP’s question, and I need the answer too.
How is Docker (as it appears in yum, etc.) different from Docker CE and Docker EE? And why aren’t there any articles online that satisfy that question with a real answer?
Cheers.
