# Note: Deployment refers to multiple environment variables, both public and private.
# Public values should be set in the .env file in the repository.
#
# Public variables are:
# * GITHUB_REPO
# * DOCKER_REPO
#
# Private values such as passwords should not be added to the source code.
# They can be set using the Travis web client.
#
# To set these, edit your repository settings in https://travis-ci.org/,
# and add them as environment variables.
# By default, any occurrence of the variable is censored in the build log.
#
# Private variables are:
# * DOCKER_USER
# * DOCKER_PASSWORD
# * PYPI_USER
# * PYPI_PASSWORD
