# Normally, you must authorized to AWS ECR to push to their registry with:
#
#   eval $(aws ecr get-login --no-include-email)
#
# If you haven't ever ran the ecr get-login command before then you'll get this error:
#
#   no basic auth credentials
#
# If you have ran it before but the auto token has expired you'll get this message:
#
#   denied: Your Authorization Token has expired. Please run 'aws ecr get-login' to fetch a new one.
#
# This class updates the ~/.docker/config.json file which is an internal docker file to automatically update the auto token for you.
# If that format changes, the update will need to be updated.
