This is a sample project that shows the implementation of microservice uisng grpc

The project consists of 2 applications built with Django and connected to each other using grpc. A full explanation fo how grpc works can be found int their documentation here https://grpc.io/. The same implemetation using pika and RabbitMQ can be found here ``.

The 2 Django applications are added as services on the docker compose file which also includes services for their respective grpc server, hence we have 4 servers running on the applications.

The application has some dependencies which need to be stated:

• git+https://github.com/profmcdan/django-grpc-framework.git@main This library is built on djangogrpcframework (can be found here https://github.com/fengsp/django-grpc-framework) which has some bugs. The bugs have been fixed in this forked version but since the owner of djangogrpcframework has not been accepting changes for some reasons, the update could not be pushed there.

• git+https://github.com/Sir-heed/micorservice-demo-with-grpc-shared-utils.git@main This in not a dependency perse, as it houses the generated grpc code based on the proto file created within the project, the grpc codes are need needed between both application, hence i packaged the folder and install them as dependencies. This is uninstalled first and then installed again to relect updated changes if there are any, this is implementec in the entrypoint.sh file.

Project Summary
