# `--Xdocker-build=<value>`

A configuration argument to be passed to the Docker build command for the app image. For example, to provide an additional build argument to the Dockerfile, specify `--Xdocker-build=--build-arg=ARG=value`. See the Docker build documentation for details on the full list of options that can be provided.

You may specify multiple `--Xdocker-build` arguments; each one specifies a single argument to pass to Docker, in the order they are specified.
