# This script is used for building Docker images which in turn build the CLI.
# It sets up the environment, logs into Docker, and builds images for different architectures.

# Before running the script, ensure DOCKER_USERNAME and DOCKER_PASSWORD environment variables are set.
# Example usage:
#   export DOCKER_USERNAME=<your-docker-hub-username>
#   export DOCKER_PASSWORD=<a-docker-hub-personal-access-token>
#   ./scripts/create-build-image.sh

# Determine the directory where the script is located.
