#
# Note: if you are running this manually, you must set a number of variables,
# not least TTN_DASHBOARD_DATA, which must be the path to the top data directory
# for these apps. If you use dashboard-ctl, this will be done for you.
#
# To get a list of all variables used in this file, use the following command:
# sed -n -e 's/[^$]*${\([^:-}]*\)[:-}][^$]*/\1\n/gp' docker-compose.yml | sort -u
#
# TTN_DASHBOARD_APACHE_FQDN
#	The fully-qualified domain name to be served by Apache.
#
# TTN_DASHBOARD_CERTBOT_EMAIL
#	The email address to be used for registering with Let's Encrypt.
#
# TTN_DASHBOARD_CERTBOT_FQDN
#	The domain(s) to be used by certbot when registering with Let's Encrypt.
#
# TTN_DASHBOARD_DATA
#	The path to the data directory. This must end with a '/', and must either
#	be absolute or must begin with './'. (If not, you'll get parse errors.)
#
# TTN_DASHBOARD_GRAFANA_ADMIN_PASSWORD
#	The password to be used for the admin user on first login. This is ignored
#	after the Grafana database has been built.
#
# TTN_DASHBOARD_GRAFANA_PROJECT_NAME
#	The project name to be used for the emails from the administrator.
#
# TTN_DASHBOARD_GRAFANA_LOG_MODE
#	Set the grafana log mode.
#
# TTN_DASHBOARD_GRAFANA_LOG_LEVEL
#	Set the grafana log level (e.g. debug)
#
# TTN_DASHBOARD_GRAFANA_SMTP_ENABLED
#	Set to true to enable SMTP.
#
# TTN_DASHBOARD_GRAFANA_SMTP_HOST_FQDN
#	The FQDN of the smtp host to be used for sending mail.
#	Defaults to localhost.
#
# TTN_DASHBOARD_INFLUXDB_ADMIN_PASSWORD
#	The password to be used for the admin user by influxdb. Again, this is 
#	ignored after the influxdb database has been built.
#
# TTN_DASHBOARD_INFLUXDB_INITIAL_DATABASE_NAME
#	The inital database to be created on first launch of influxdb. Ignored
#	after influxdb has been launched.
#
# TTN_DASHBOARD_PORT_HTTP
#	The port to listen to for HTTP. Primarily for test purposes. Defaults to 
#	80.
#
# TTN_DASHBOARD_PORT_HTTPS
#	The port to listen to for HTTPS. Primarily for test purposes. Defaults to 
#	443.
#
# Also see apache/setup.sh, which uses some additional test variables when
# debugging.
