Open-source docker image availability

When using the example include `docker-compose.yaml` file, it builds the API server locally and is able to boot up. When using the dockerhub image available on https://hub.docker.com/r/appbaseio/reactivesearch-api, it fails to boot asking for a valid `APPBASE_ID`.

Could this be happening because of the build args not being opensource? https://github.com/appbaseio/reactivesearch-api/blob/dev/Dockerfile#L3-L18

My modified docker-compose file:

```yaml

latest

### What issue did you run into?

### What did you expect to see?

### What did you see instead?

Comienza con docker-compose.yaml, config/docker.env y las líneas 3-18 de Dockerfile; después compara la imagen de API compilada localmente con appbaseio/reactivesearch-api:8.20.3. Ejecuta el comando de Compose mostrado y rastrea el fallo de inicio de APPBASE_ID; se considera terminado cuando la imagen de Docker Hub arranca con la misma configuración de ejemplo o su entorno requerido está claramente documentado.
