How to run urbackup-server-web-api-wrapper from server running in docker container

Hi folks,
I recently migrated from a bare metal to docker and it’s running fine, but on older server I was running urbackup-server-web-api-wrapper (GitHub - uroni/urbackup-server-python-web-api-wrapper: Python wrapper to access and control an UrBackup server) to script some backup information collect, but now on a container I cannot install it to run scripts because the docker image cannot reach internet.
Did you know a way to install it with this scenario?
Thank you in advance.
