# MariaDB HTTP Check

Small HTTP service for checking MariaDB connectivity from the Nubes HTTP runtime.

Configuration is read from `DB_HOST`, `DB_PORT`, `DB_NAME`, `DB_USER`, and `DB_PASSWORD`.
The default listening port is `8080`; it can be changed with `PORT`.

- `GET /healthz` checks that the process is serving requests.
- `GET /readyz` checks MariaDB with `SELECT 1` and returns `503` while the database is unavailable.
- `GET /` returns the same readiness status as `/readyz`.

Build the container image with:

```sh
docker build -t naeel/mariadb-check:0.1 .
```
