Giving the backend software infrastructure some love (2021)

Andreas · February 13, 2021, 10:30pm

Hi there,

we just wanted to let you know that we started to work on a refresh of the backend infrastructure. Kotori has finally(!) been ported to Python 3 with version 0.26.0 [1] and we are just working on overhauling the packaging process.

On the foundation infrastructure side, we are still running Grafana 6.7 and would like to upgrade to Grafana 7.4 [2]. When looking at Mosquitto, version 2.0 has been released in December 2020 [3] which improves support for the MQTT v5 protocol, see also MQTT5 is coming and Mosquitto 1.6 with MQTT v5 arrived.

Last but not least, InfluxDB version 2 is also available since November 2020 [4], see InfluxDB 2.0 is coming. However, we will go with InfluxDB 1.8 first, we are still running version 1.7.10.

With kind regards,
Andreas.

Mosquitto 2.0

Please note that Mosquitto 2.x introduced a breaking change. However, it was a good decision because it strengthens the security on default installations.

So, in order to make Mosquitto listen on the public interface and accept anonymous requests again, you will have to configure your /etc/mosquitto/conf.d/default.conf like that:

github.com

eclipse/mosquitto/blob/12ff9d5e/docker/2.0/mosquitto-no-auth.conf

# This is a Mosquitto configuration file that creates a listener on port 1883
# that allows unauthenticated access.

listener 1883
allow_anonymous true

Grafana 7

On https://weather.hiveeyes.org/, we are now running Grafana 7. The upgrade was pretty straight forward. Kudos to the lovely people at Grafana Labs.
