# NOTES
# This file is a self-contained description of a Concourse CI pipeline
# to deploy a http://gosparta.io application.  There's a couple of things to 
# note:
#   - The YAML uses node references so that scripts can be defined in the 
#     CONSTANTS key and referenced in the jobs section
#   - This requires an additional YML file that defines AWS credentials and the
#     S3 bucket that should be used for storage. Required keys:
#       s3-bucket: XXXXXX
#       s3-access-key-id: XXXXXXXXXXXXXXXXXX
#       s3-secret-access-key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
