# THIS IS AN EXAMPLE
#
# Example Dockerfile showing one way to run Tornado.
# Adjust components and configuration to suit your own environment,
# standards, and operational requirements.
#
# Note: the Tornado Console password must be set or explicitly disabled
#       (see commented settings near the bottom of this file).
#       Without a password set, security of the configuration and operation
#       of Tornado relies heavily on local network and host security.
