# Utility script to stage Docker images in a public ECR repository so they can

# referenced in Dockerfile's without depending on Docker Hub (and therefore

# at risk of being rate limited and failing builds).

# Prerequisites:

# 1. Credentials for the Retail Demo Store staging AWS account where public

# images are staged.

# 2. Your local AWS CLI environment configured with credentials to access

# the above mentioned account.

# 3. AWS CLI 2.16+ (for ecr-public commands).
