# =============================================================================
# BAUER GROUP XPD-RPIImage - tools container
#
# Portable dev/test runtime: validate JSON configs, render CustomPiOS module
# artifacts and orchestrate full image builds on any host with Docker.
#
# This container is NOT privileged. The actual image build launches
# guysoft/custompios as a sibling container via the host docker.sock.
