Prometheus

Prometheus - Monitoring system and time series database.

When application is installed, a container will be launched with root privileges. This is required in order to apply the correct permissions to the prometheus directories. Afterward, the prometheus container will run as a non-root user (Default: 568). Also an empty configuration file will be created.

The configuration file is located at /config/prometheus.yml inside the container. Data is stored at /data inside the container.
