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.
--contextdir
Build context directory. Specifying a context directory causes Buildah to chroot into a the 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 copied content.
buildah copy containerID '/myapp/app.conf' '/myapp/app.conf'
buildah copy --chown myuser:mygroup 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
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:
