Build and Run

• You should install docker and docker-compose

• To build application run:

sh build.sh

• After building, you can run the following:

docker-compose up

Documentation

After running the application you can access the documentation by following url:

http://localhost:8080/swagger-ui/index.html

• http://localhost:8080 is the default endpoint

Test

To isolate testing environment, I considered separate docker file and docker compose file for running test. Also I considered docker compose to have an instance of postgres for testing purposes.

To run tests you can run the following command:

sudo docker-compose -f docker-compose.test.yml up --build

• After running tests, terminate it by CTRL + c or docker-compose -f docker-compose.test.yml down

Note:

• It's better to implement exchange rate service provider more modular

• It's better to set exchange rate api access key as a ENV variable

• Because of problems after creating jar file to access swagger endpoint, I use ./mvnw spring-boot:run in docker file

• To isolate testing environment, I considered separate docker file and docker compose file for running test
