using bamboo to chain together docker containers in a pipeline

Question

I'm using Bamboo 9.0 to build docker containers from a dockerfile. The first build plan is the production environment of some application. This build plan completes successfully and is configured to save the resulting docker image as prod_img.tar as an artifact. The second build plan starts with prod_img.tar and adds C++ compiler, cmake, etc.. it is the build environment for some application.

How do I configure bamboo to take the artifact prod_img.tar from build plan 1 and make it available as the base for a dev environment container in build plan 2?

Build Plan 2 is triggered on completion of build plan 1 (the production docker image) and is configured to check out a dockerfile from Git

Next, I try to supply prod_img.tar to Build Plan 2

The dockerfile in Build Plan 2 should use the --build_arg to start with FROM prod_img.tar.

## [Choice] define only the registry to pull the production image from
ARG REPOSITORY=my_local_repository:9999
## [Choice] define only the production image 
ARG BASE=my_production_image
## [Choice] define only the version of the production environment container to use as a base
ARG VARIANT=latest
## [Choice] fully define the base image
ARG BASE_IMAGE=${REPOSITORY}/${BASE}:${VARIANT}
FROM ${BASE_IMAGE}
USER root

# go on to install compiler, cmake, etc...

This fails because prod_img.tar isn't in any docker registry. How should I tell bamboo to chain the result of Build Plan 1 to the input of Build Plan 2? Is there some reliable way to use docker load for this?
