I would nitpick this. You build images not containers and since files are not copied by default there is more nuance here that the .dockerignore file makes builds faster by not including them in the build context.

That does ultimately prevent COPY directives from using them but it is these sorts of brief, slightly inaccurate summaries that mislead folks as they build understanding.

Shouldn't the speeding up of the build make the program less boring? From my understanding, the program gets more boring as the time it takes an application to build increases.
