+# vault
+
+## Configuration
+
+Three dotenv files are expected under `/etc/opt/...`:
+
+```bash
+# vault-exporter.env
+
+DATA_SOURCE_URI=<db-host>:<db-port>?sslmode=disable
+DATA_SOURCE_USER=<db-user>
+DATA_SOURCE_PASS=<db-pass>
+```
+
+```bash
+# vault-db-init.env
+
+POSTGRES_PASSWORD=<db-pass>
+```
+
+```bash
+# vault-db.env
+
+DATABASE_URL=<db-connection-string>
+```
+
+## Volumes
+
+The service will set up two volumes:
+
+- `vault_db` - Postgres data volume used for persistent storage;
+- `vault_data` - Persistent storage for the application itself.
+
+## Ports
+
+The application is accessible via `:8082`.
+
+Other ports are exposed (i.e. `:8083`) to allow telemetry polling.
