# Summary
The container image is based on Alpine Linux and sends a curl request result with the [mosquitto-client](https://mosquitto.org/)
to a MQTT server topic.
# Prerequisites to run the docker container
You need an MQTT server to send the data to it.
# Configuration

|--|--|--|--|
| `MQTT_SERVER` | The MQTT server hostname or IP address | **OPTIONAL** | `localhost` |
| `MQTT_PORT` | The TCP port of the MQTT server | **OPTIONAL** | `1883` |
| `MQTT_TLS_enabled` | Should SSL communication be enabled (`true`) or not (`false`) | **OPTIONAL** | `false` |
| `MQTT_CACERT_FILE` | If TLS is enabled, the path to the CA certificate file to validate the MQTT server certificate | **OPTIONAL** | |
| `MQTT_TLS_no_hostname_validation` | If TLS is enabled, skip the hostname validation of the TLS certificate | **OPTIONAL** | `false` |
| `MQTT_USER` | The MQTT username for MQTT authentication | **OPTIONAL** | |
| `MQTT_PASSWORD` | The MQTT password for MQTT authentication | **OPTIONAL** | |
| `MQTT_PASSWORD_FILE` | The filepath where the MQTT password is stored for MQTT authentication | **OPTIONAL** | |
| `MQTT_TOPIC` | The MQTT topic to send the docker hub statistics to | **MANDATORY** | |
| `MQTT_RETAIN`| Set the retain flag when publishing the docker hub statistics to MQTT topic | **OPTIONAL** | `false` |
| `REPOSITORIES` | A whitespace separated list of docker hub repositories where to collect the statistics | **MANDATORY** | |
| `MQTT_TOPIC_REPO_EXTENSION` | Use the docker hub repository name as MQTT topic appendix | **OPTIONAL** | `false` |
