# Build the ExaBGP Docker image and export it for CML 2.9 import.
#
# Usage:
#   ./cml/build-cml-image.sh
#
# Output:
#   /tmp/obmp-exabgp.tar  — upload this to CML via:
#     Tools > Node and Image Definitions > Image Definitions > Manage Image Uploads
#
# After upload, also import the node + image definition YAMLs:
#   Tools > Node and Image Definitions > Import > cml/exabgp-node-definition.yaml
#   Tools > Node and Image Definitions > Import > cml/exabgp-image-definition.yaml
