buildah-add(1)

NAME

buildah-add - Add the contents of a file, URL, or a directory to a container.

SYNOPSIS

buildah add [options] container src [[src ...] dest]

DESCRIPTION

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.

OPTIONS

--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.

--contextdir

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.

--ignorefile

Path to an alternative .dockerignore file. Requires --contextdir be specified.

--quiet, -q

Refrain from printing a digest of the added content.

EXAMPLE

buildah add containerID '/myapp/app.conf' '/myapp/app.conf'

buildah add --chown myuser:mygroup containerID '/myapp/app.conf' '/myapp/app.conf'

buildah add containerID '/home/myuser/myproject.go'

buildah add containerID '/home/myuser/myfiles.tar' '/tmp'

buildah add containerID '/tmp/workingdir' '/tmp/workingdir'

buildah add containerID ' ⟨https://github.com/containers/buildah/blob/master/README.md'⟩ '/tmp'

buildah add containerID 'passwd' 'certs.d' /etc

FILES

  .dockerignore

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:

    *.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:
