### Run with Docker
Use the docker file to build the image. With docker, the script will run every 3600 seconds. (This value can be changed in the Dockerfile.
### Limitations
The XML-RPC API has a limit of 30 requests per 2 seconds, so i guess it's safe to update 25 subdomains at once with the REST API.
