# Example call:
# ansible-playbook upload-database-dumb.yml --ask-vault-pass -e "cluster_features=['connect',...] cluster_size='1' stage='dev' upload_file='dumps/import.sql' uploaded_file='import.sql'

# How this stuff works:
# If `upload_file` is defined the upload role save the binary to `upload_directory` (default /tmp)
# If `database_backup_file` and `target_database` are defined the import role imports from file basename `database_backup_file` to `target_database`
# If both role conditions match the upload role trigger first.

# Parameters:
#   playbook inventory
#     stage := the name of the stage (e.g. dev, int, qa, prod)
#     cluster_features := (services to setup, e.g. ['connect', 'wordpress', ...])
#     upload_file := the local file to upload (e.g. dumps/wordpress_portal.sql)
#     database_backup_file := the dump file to import (e.g. wordpress_portal.sql)
