What is the ADD instruction good for in Docker?

Experience Level: Senior
Tags: Docker

Answer

The ADD instruction copies new files, directories or remote file URLs from <src> and adds them to the filesystem of the image at the path <dest>.

Multiple <src> resources may be specified but if they are files or directories, their paths are interpreted as relative to the source of the context of the build.

Each <src> may contain wildcards and matching will be done using Go’s filepath.Match rules.

Example:
ADD hom* /mydir/
