Required version
The first section describes each of the dependencies and the minimum version required. In our example, we stipulate that thoughts_backend needs to be version v1.6 or up:
import osVERSIONS = { 'thoughts_backend': (f'{os.environ["THOUGHTS_BACKEND_URL"]}/admin/version', 'v1.6'),}
This reuses the environment variable, THOUGHTS_BACKEND_URL, and completes the URL with the specific version path.
The main section goes through all the dependencies described to check them.
