NanoMQ MQTT broker

Starts a NanoMQ MQTT broker.

Authentication

The broker is configured to use a simple username/password authentication. See ./nanomq_pwd.conf for the default credentials.

TLS Certificates

If you want to configure an MQTT contact point in Grafana Alerting with TLS, you need to provide a certificate and key.

You can find them in /etc/certs directory in the container:

docker exec devenv-mqtt-1 ls /etc/certs/

CA Certificate

docker exec devenv-mqtt-1 cat /etc/certs/ca.pem

Client certificates

docker exec devenv-mqtt-1 cat /etc/certs/client.pem
docker exec devenv-mqtt-1 cat /etc/certs/client.key
