Hands-On Microservices with Kubernetes

Building a Python-based API gateway service

The API gateway service is designed to receive all requests from outside the cluster and route them to the proper services. Here is the directory's structure:

$ tree . ├── Dockerfile ├── README.md ├── api_gateway_service │   ├── __init__.py │   ├── api.py │   ├── config.py │   ├── news_client.py │   ├── news_client_test.py │   ├── news_pb2.py │   ├── news_pb2_grpc.py │   └── resources.py ├── k8s │   ├── api_gateway.yaml │   ├── configmap.yaml │   └── secrets.yaml ├── requirements.txt ├── run.py └── tests     └── api_gateway_service_test.py

This is a little different from the Go services. The code is under the api_gateway_service directory, which is also a Python package. The Kubernetes resources are under the k8s subdirectory, ...
