build_images.sh

#!/bin/bash
#
# Build Docker images from artifacts produced by ./local.sh all
#
# This is a convenience wrapper. The image build commands are also available
# from within ./local.sh shell as:
#   ./local.sh build_agent_image
#   ./local.sh build_cluster_agent_image
#   ./local.sh build_images
#
# Usage (from host):
#   ./build_images.sh [agent|cluster-agent|all]
#
# Environment variables:
#   REGISTRY    - Registry to tag for (e.g., registry.example.com)
#   ORG         - Organization/namespace (default: stackstate)
#   IMAGE_TAG   - Image tag (default: git short SHA)
#   ARCH        - Architecture (default: amd64)
#
