Dockerfile ADD

Definition:

• Copies new files or directories from <src> and adds them to the filesystem of the image at the path <dest>.

  • Similar to Dockerfile COPY but can fetch files from remote HTTPS and Git and extracting tar files automatically when adding files from the build context

    ```dockerfile
      ADD https://example.com/archive.zip /usr/src/things/
      ADD [email protected]:user/repo.git /usr/src/things/
      ```
    

  • Files and directories can be copied from the build context, a remote URL, or a Git repository.
  • The last argument must always be the destination
  • If you specify multiple source files, either directly or using a wildcard, then the destination must be a directory (must end with a slash /)
    • ex: ADD file1 file2 /dest/

•   ADD [OPTIONS] <src> ... <dest>
    ADD [OPTIONS] ["<src>", ... "<dest>"]

  • OPTIONS:
