I am trying to reuse some code within my python project, within an Azure Function, it is structured as follows: myproject/ | - a_app/ | - b_app/ | - c_lib/ | - requirements.txt Up until now I have been conveniently avoiding sharing code between my 2 separate modules a_app and b_app. But I now want to create some classes that I can share and place it within c_lib. I have an Azure function here: myproject/ | - a_app/FunctionA/init.py It is referencing the library c_lib by importing using the following statement: from c_lib.foundation_utility.jwt_enforced_permissions import JWTEnforcedPermissions All the tests pass locally and the reference is imported successfully but when I deploy to my Azure Function it simply can't find the library (an example class I'm trying to share): File "/home/site/wwwroot/FunctionA/init.py", line 10, in from c_lib.foundation_utility.jwt_enforced_permissions import JWTEnforcedPermissions File "/home/site/wwwroot/c_lib/foundation_utility/jwt_enforced_permissions.py", line 4, in from foundation_utility.i_token_permissions import ITokenPermissions For the life of me I can't figure out why it can't find the library. I am trying to browser the Azure Function folder structure so that I can figure out where the file is actually located to reconcile why it's not working. Given that I have been able to reference various classes within my a_app and b_app respectfully, but not referencing one another, I know how to successfully call the right namespace. I therefore thought about copying the c_lib into the folders of a_app/ and b_app/ respectfully as part of a github build action: - name: Copy c_lib into Function App Directory run: | cp -r c_lib a_app/ However despite doing this and trying to reference c_lib from within a_app it still not working. I also considered creating this library as a pip module, but that's not what I'm looking for as I want to deploy the library as the same version as a_app and b_app. I don't want version invariance. Something about the Azure Function means that it can't access code beyond its own package. Continue reading...
