Otto Microservice

This project is the implementation of a simple RESTful microservice, which queries an existing API and has the functionality to filter and transform its contents.

Running the application

• Run make all to execute all the tests, build the executable and docker image.
• If only the docker image is needed, run make docker or docker build -t <image-name> ..
• To just build and run the application, call make run, or make docker-run respectively for building and running the docker container. The second command will only properly work on Linux hosts, since it lets the Docker container use the host network driver to run directly on the port which is specified inside the server. On other systems, the port has to be manually mapped when starting the container.

Configuration

There is a configuration file config.yaml in the project root which allows to configure the server. This file has to reside next to the server binary. It allows to configure the following parameters:

• apiKey: The API key of the queried API (default: key given in task description)
• port: The port that the server will listen on (default: 8080)
• logging-level: Level of logging in the application (debug|info|warn|error|fatal) (default: info)
