This small repository is designed as an example of how to solve the common case of wanting a protobuf schema repository shared between multiple microservices. This works out of the box for most languages, but due to the issues discussed in protobuf/1491, it is tricky to accomplish for Python services.
Using this method, you can keep your schema repository as is (see the contents
of example_proto/, adding only minimal Python packaging artifacts to the top
level. This will allow you to install (and automatically compile) the Python
generated code with pip install /path/to/this/repo. For example:
$ virtualenv -p python3 venv
$ source venv/bin/activate
(venv) $ pip install 'git+https://github.com/sbrother/python-protobuf-repo-example'
(venv) $ python
>>> from example_proto.food_pb2 import Food
>>> # success!
Under the hood this uses a custom setuptools command.
