I’ve been looking into efficient ways of reducing bloat when building an image manually.
I wanted to ask if anyone had insight on what happens when the COPY command is issued on a directory that already exists in the build where a lot of the files are exact duplicates of each other.
Does the image growth reflect:
- the difference between the changed files after the overwrite?
- the entire size of the directory being copied?
If it’s the second case are there any efficient ways to update an entire directory recursively from another build stage?
