Hello World

A three-service example for Vers Repos:

Frontend (nginx) -> Backend (FastAPI) -> Database (PostgreSQL)

The example displays a persisted visit counter.

Run locally

docker compose up --build -d
./scripts/verify-compose.sh

Open http://localhost:8080.

The database's HTTP gateway runs as the unprivileged postgres user and listens on port 8080, configurable through PORT. PostgreSQL itself listens on 127.0.0.1:5432. Compose publishes the gateway at http://localhost:8082 and connects the backend to http://database:8080.
