This is simple GRPC implementation. It will be handle grpcserver and keep the information.

To run this application you need two repo

| This is simple Demo Application as Microservices between 2 server.

1. webServer: which is running Flask-Server and also sending some traces to the grpcServer
2. grpcServer: It is accepting data like

Message Received: page_name: "http://127.0.0.1:5000/"      
client_address: "127.0.0.1:5000"                           
request_body: "{}"                                         
, content: <grpc._server._Context object at 0x7f9beb477290>

---

Now, Let's discuss how we can start it.

1. clone the repos
2. build docker with following command

$ docker build -t flaskserver:latest .
$ docker build -it grpcserver:latest .

3. before running the docker image, create a network

$ docker network create idocnet

4. now, run the images in the network

$ docker run --rm -it --network idocnet --name flaskserver -p 5000:5000 flaskserver
$ docker run --rm -it --network idocnet --name grpcserer grpcserer

Now, we can set environment to the container while firing it up either using method mentioned in step 4 or through kubernetes. Default port is 50051 for GRPC. we can customize it during runtime.

$ docker run --rm -it --network idocnet -e HOST='50051' --name grpcserer grpcserer

5. now, inspect the network and take a look if all services are attached to network or not.

$  docker network inspect idocnet
