# This script uses the archive-server (https://github.com/tsuru/archive-server)
# to generate archives and deploy applications using them.
#
# It depends on the following environment variables:
#
#   - ARCHIVE_SERVER_READ: the base URL that will be sent to the tsuru server,
#                          is a public URL that will be used to serve the
#                          archive (for example: http://archive-server:8080)
#   - ARCHIVE_SERVER_WRITE: the base URL that will be used to generate the
#                           archive, it's commonly a private URL (for example:
#                           http://127.0.0.1:8181)
#   - TSURU_HOST: URL to the Tsuru API (for example: http://yourtsuru:8080)
#   - TSURU_TOKEN: the token to communicate with the API (generated with
#                  `tsurud token`, in the server).
