This repo contain a tutorial guide to use flask and grpc side by side by side,, and also showing how you can share the codes among the different apps in docker container
You have to install docker and docker-compose to run this app, if you already have installed then you just have to run following commands
docker-compose build and wait docker to build everything once done
docker-compose up -d to run docker in background
docker-compose ps Will show you the running instance of docker ( Everything should be up and running )
--------------------------------------------------------------------------------------------
grpc-flask-tutorial_db_1 /docker-entrypoint.sh mysqld Up 0.0.0.0:5016->3306/tcp
grpc-flask-tutorial_grpc_1 python ./app.py Up 0.0.0.0:50051->50051/tcp
grpc-flask-tutorial_web_1 python application/app.py Up 0.0.0.0:3001->3001/tcp
Just curl your localhost with port 3001
curl -d '[{"name":"ABC", "birth":"2019-01-24", "gender": "MALE"}]' -H "Content-Type: application/json" -X POST http://localhost:3001/users
curl localhost:3001/user/1
curl localhost:3001/users
If you have client setup outside the docker then you call the grpc function using localhost:50051 and it should give you the data. But here we will test is little differently ( Not recommended in productions ), I am doing this because I already have small written client script.
You have to go inside the running grpc docker instance
docker exec -it grpc-flask-tutorial_grpc_1 sh
You will see new bash shell, Now we have to lunch python terminal so just type
python
You will see python terminal, now you need to import client file and the get_user and get_users function
from client import get_user, get_users
Once imported then, just call function
get_user(1) you will see result , if you have data or not found error
get_users() it will give you all data
