buildah-copy - Copies the contents of a file, URL, or directory into a container's working directory.
buildah copy container src [[src ...] dest]
Copies 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 directory is specified as a source, its contents are copied to the destination.
--add-history
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. export BUILDAH_HISTORY=true
--chown owner:group
Sets the user and group ownership of the destination content.
--quiet
Refrain from printing a digest of the copied content.
buildah copy containerID '/myapp/app.conf' '/myapp/app.conf'

buildah copy containerID '/home/myuser/myproject.go'
buildah copy containerID '/home/myuser/myfiles.tar' '/tmp'
buildah copy containerID '/tmp/workingdir' '/tmp/workingdir'
buildah copy containerID 'https://github.com/containers/buildah' '/tmp'
buildah copy containerID 'passwd' 'certs.d' /etc
If the file .dockerignore exists in the context directory, buildah copy reads
its contents. Buildah uses the content to exclude files and directories from
the context directory, when copying content into the image.
Users can specify a series of Unix shell globals in a .dockerignore 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:
*.doc
!Help.doc
Exclude all doc files except Help.doc from the image.
This functionality is compatible with the handling of .dockerignore files described here:
