Documentation of the Docker development environment¶
This documentation provides an overview of the Docker containers used, as well as their function and their addresses.
Overview of the containers¶
| Container | Image | Description | Adress |
|---|---|---|---|
| traefik | traefik:3.4.4 | Reverse proxy and load balancer for external access to our containers (HTTPS certificates) | traefik.localhost, Ports: 80, 443, Dashboard-Port: 8432 |
| influxdb | influxdb:3.2.1-core | Time series database (InfluxDB 3.x) for data storage | Port: 8181 |
| influxdb-explorer | influxdata/influxdb3-ui:1.0.3 | Web interface for managing and querying InfluxDB data | explorer.localhost, Port: 8888 |
| postgres | postgres:alpine3.21 | PostgreSQL database for relational data storage | Port: 5432 |
| loki | grafana/loki:3.5.2 | Log aggregation and management | Port: 3100 |
| prometheus | prom/prometheus:v3.4.2 | Monitoring tool for collecting and evaluating metrics | Port: 9090 |
| alloy | grafana/alloy:v1.9.2 | Observability platform for the integration of Loki and Prometheus | Ports: 12345, 4317, 4318 |
| grafana | grafana/grafana:12.0.2 | Web-based visualization and dashboard for metrics and logs | grafana.localhost |
| isopruefi-frontend | own Build (React) | Frontend Application | frontend.localhost |
| isopruefi-backend-api | own Build (.NET REST-API) | Backend REST API for application logic | backend.localhost |
Networks¶
The following Docker networks are used to logically separate the containers from each other:
isopruefi-network: General network, used by Traefikdatabase-network: Network for databases (InfluxDB, PostgreSQL)isopruefi-custom: Network for user-defined services (frontend, backend)loki: Network for observability tools (Loki, Grafana, Alloy)
Details of important containers¶
Traefik¶
Traefik serves as a reverse proxy that receives all HTTP(S) requests and forwards them to the appropriate Docker containers. It automatically manages the TLS certificates and provides a dashboard for administration.
Grafana¶
Grafana is used to visualize and analyze logs and metrics. It is connected to Loki (logs) and Prometheus (metrics).
InfluxDB und InfluxDB-Explorer¶
InfluxDB stores time series data, while InfluxDB Explorer provides a convenient web interface to access this data.
PostgreSQL¶
PostgreSQL stores relational data used by the backend API.
