# Start a Concordium node deployment using Docker Compose with node images pulled from an external registry.
# 
# Usage:
# 
#   NODE_NAME=<node-name> ./run.sh <network>
# 
# where <network> is the network on which the node is intended to join
# and <node-name> is the name of the node to appear on CCDScan for that network.
# 
# The parameters of the deployment are loaded from an environment file <network>.env in the current working directory.
# All images referenced in this file are expected to be pullable from the appropriate image registry.
# 
# Environment files are predefined for the public Testnet and Mainnet networks.
# They reference the newest versions of the images built using a CI workflow in this project (see the readme for details).
