Maybe I’m confused, but from what I understand, “declarative” means you tell the computer what you want the final thing to look like, and “imperative” means you tell the computer what steps to take. So Dockerfile would be imperative because it’s a set of commands that are executed in-order to create the image. Meanwhile docker-compose.yml is declarative because you say which containers are used with what options and how they’re interconnected. IDK tho, as far as I understand the definitions aren’t that rigid
