+## Seed and clear DB
+DB is at the start of the app seeded with some Data, thus you don't have to do it manually. 
+For users are available 2 endpoints:

+- /seed - Seed DB with some Data
+- /clear - Clear DB whenever during running

+Create network for being able to communicate between two separate

+
+To collect the metrics in an automated way we use Prometheus.
+First, make sure that every service you want to observe is running on predefined port.
+Then run Prometheus in docker with respect to location of `prometheus.yml` file:
+
+```bash
+docker run --rm --name prometheus --network grafana-prometheus --network-alias prometheus -p 9090:9090 -v ${PWD}/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus:v2.43.0 --config.file=/etc/prometheus/prometheus.yml

+
+```bash
+docker run --rm --name grafana --network grafana-prometheus -p 3000:3000 grafana/grafana:9.1.7
