+# InfluxDB's configuration variables (including how each CONFIGURATION
+# variable maps to an ENVIRONMENT variable for use in this file) can
+# be found at:

+#   https://docs.influxdata.com/influxdb/latest/administration/config/#configuration-settings
+#
+# The URL was correct as at 2020-10-11 but is subject to change.

+# ---------------------------------------------------------------------
+
+
+# enable INFLUXDB_HTTP_AUTH_ENABLED to enforce authentication for access
+# via HTTP and HTTPS. Node-Red, Grafana and the "influx" command line
+# interface all use HTTP/S so enabling this option affects pretty much
+# everything. Only enable this option AFTER you have set up credentials
+# for your database administrator, like this:
+#
+#   CREATE USER "dba" WITH PASSWORD 'supremo' WITH ALL PRIVILEGES
+
+INFLUXDB_HTTP_AUTH_ENABLED=false
+
+
+# if INFLUXDB_HTTP_AUTH_ENABLED=true then INFLUX_USERNAME and
+# INFLUX_PASSWORD supply database administrator (DBA) credentials to
+# the "influx" command line interface. They serve no other purpose. They
+# are NOT general-purpose credentials for use in NodeRed or Grafana etc.
+# If INFLUXDB_HTTP_AUTH_ENABLED is enabled but INFLUX_USERNAME &
+# INFLUX_PASSWORD do not match the values on the CREATE USER statement
+# then you will need to authenticate when you start the "influx" CLI.

+INFLUX_USERNAME=dba
+INFLUX_PASSWORD=supremo

+
+# enable UDP support
+
+INFLUXDB_UDP_ENABLED=false
+
+
+# if INFLUXDB_UDP_ENABLED=true then InfluxDB listens for line protocol
+# data on UDP port 8086. In the context below, the IP address "0.0.0.0"
+# means "this host"; analogous to the way "255.255.255.255" means
+# "all hosts"
+
+INFLUXDB_UDP_BIND_ADDRESS=0.0.0.0:8086
+
+# Remember that you will need a matching  "ports" definition in your
+# docker-compose.yml. For example:
+#
+#     - "8086:8086/udp"
+#
+# Also remember that, just because InfluxDB running inside the container
+# is listening on UDP/8086, does NOT mean that the external port MUST be
+# the same. It could just as easily be "8089:8086/udp". Keep that in
+# mind when you set up the sending process.
+
+
+# if INFLUXDB_UDP_ENABLED=true then data will be written to the
+# database named "udp". You MUST create this database, by hand via
+# the "influx CLI", before you start sending data, as in:
+#
+#   CREATE DATABASE udp
+
+INFLUXDB_UDP_DATABASE=udp
