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
