Using a licencse file on client CI #122

Open BotellaA opened 3 years ago

BotellaA commented 3 years ago

I would like to know if there is a way to provide a license file to a client, so he could use it on a third party CI, like Github Actions.

We could generate a license without any PC information but this unrestricted license file should not be given to a client.... Do you see a way to lock or control the usage on a third party CI?

Thanks for your help

Hi Arnaud, The original idea was to detect the virtualization environment the CI use and some VM parameters: eg, your demo application can only run on Google Cloud with less than XX of ram and less than X cpu. That's the best i can think of. Another idea could be a timer: your application can only run for xx minutes (time of the tests) then it stops...

The VM detection code is already there, but i couldn't complete the verification part, and seems my plan to work on it are to be further postponed. A first plain implementation shouldn't be that difficult: add the parameters into the license generator and verify against them in the library... BR Gabriele

Thanks for the reply. What is missing for the verifcation part? The specifications for each CI?

Hi Arnaud, The class ExecutionEnvironment has already an enum to return wihch cloud provider you are executing in. The license generator should be able to generate a license limiting to a cloud provider (eg.add one line into the license file like: cloud-provider=GCP ) in LicenseVerifier::verify_limits read the line above (it's in the m_limits map in FullLicenseInfo) and if present validate it with the current value from ExecutionEnvironment
