buildah add [options] container src [[src ...] dest]
Adds the contents of a file, URL, or a directory to a container's working directory or a specified location in the container. If a local source file appears to be an archive, its contents are extracted and added instead of the archive file itself. If a local directory is specified as a source, its contents are copied to the destination.
- Add an entry to the history which will note the digest of the added content. Defaults to false.
Note: You can also override the default value of --add-history by setting the BUILDAH_HISTORY environment variable.
- --chown owner:group
- Sets the user and group ownership of the destination content.
- Build context directory. Specifying a context directory causes Buildah to chroot into that context directory. This means copying files pointed at by symbolic links outside of the chroot will fail.
- Path to an alternative .dockerignore file. Requires --contextdir be specified.
- --quiet, -q
- Refrain from printing a digest of the added content.

When the \fB\fC--ignorefile\fR option is specified Buildah reads the content to exclude files and directories from the source directory, when copying content into the image.
Users can specify a series of Unix shell globals in a ignore file to identify files/directories to exclude.
Buildah supports a special wildcard string
** which matches any number of directories (including zero). For example, */.go will exclude all files that end with .go that are found in all directories.
Example .dockerignore file:
# here are files we want to exclude */*.c **/output* src
*/*.c Excludes files and directories whose names ends with .c in any top level subdirectory. For example, the source file include/rootless.c.
**/output* Excludes files and directories starting with
output from any directory.
src Excludes files named src and the directory src as well as any content in it.
Lines starting with ! (exclamation mark) can be used to make exceptions to exclusions. The following is an example .dockerignore file that uses this mechanism:
Exclude all doc files except Help.doc from the image.
This functionality is compatible with the handling of .dockerignore files described here:
