| The `--pull` flag forces Docker to check for and download a newer | ||
| version of the base image, even if you have a version cached locally. | ||
| It only affects the `FROM` instruction — cached `RUN` layers are still | ||
| reused. |

There was a problem hiding this comment.
Addition is redundant: remove it. This entire section talks about base images. RUN layers are not base images.

Summary
--pullsection: adds that the flag only affects theFROMinstruction — cachedRUNlayers are still reused. This prevents readers from assuming--pullalone gives them fresh dependencies.--no-cachesection: replaces the "however... doesn't pull a fresh base image" correction with a positive cross-reference to--pull, and reframes the combined usage as two complementary flags rather than a workaround.Issue
Fixes #25291
