# Pull latest source from Gitea, rebuild the local image, and restart the
# container. Intended for the "Unraid builds locally" deploy path documented
# in docs/DEPLOY.md §5. Run it on the Unraid host, not inside the container.
#
# Usage:
#   SRC_DIR=/mnt/user/appdata/mrp-qrcode-src \
#   IMAGE=mrp-qrcode:local \
#   CONTAINER=mrp-qrcode \
#   docker/rebuild.sh
#
# Wire it up as a User Scripts plugin cron job to get poor-man's CI.
