Fibonacci

Fibonacci is a service that calculates a numerical interval from x to y inclusive from the Fibonacci series. The service does not recalculate the numbers, but takes them from the cache if they are present there.

Delivery

Service communicates using two protocols: gRPC and HTTP. Service considers all HTTP2 traffic is gRPC requests.

HTTP

GET /fibonacci?x=1&y=2

x and y are non-negative integers greater than 1. x is less than or equal y

gRPC

Proto file can be found here. You can also compile gRPC Client to test out gRPC work:

make build-client

Then run:

./grpc_client -x=1 -y=5

Deployment

To start the service simply run:

make up

Application listens on :8080 and Redis listens on :6379 by default, so these ports must not be taken by another processes. In order to change ports simply modify docker-compose.yml file. Run make down to stop all containers.

Tests

To run the tests run:

make test
