1. Write a Flask application implementing a REST API to serve the content of the colors.json file. Feel free to add any framework/library which you think is necessary for this purpose. The user should be able to perform the following operations:
   • Retrieve the whole list of colors
   • Retrieve a single color from the list
   • Insert a new color into the list
2. Write automated tests for the API. You can use any tool/framework which you think is necessary to do that.
3. Prepare your application to be deployed and executed in a containerized environment, using podman. Provide the needed files for the deployment.
4. Provide documentation for deployment and utilization of the API. You may use any kind of format for the documentation.

How to use / Deployment

Prerequisites:

• podman and make commands available on PATH;
• internet connection.

Run tests

Command: $ make test

It will build the image using podman, create a container and run the tests on it. The test suite consists of:

• Few unit tests for the model and API;
  • A coverage report is provided after the execution.
• Linting errors on code using pylint.

Run server

Command: $ make run

It will build the image using podman, create a container and run the webserver on http://localhost:5000/.

API documentation

• All responses from API are in JSON format;
  • The colors are represented by a dictionary having the color name and its value in RGB hex with three or six digits. For instance:

  {
    "color": "black",
    "value": "#000"
  }

• All data sent (post) to API need to be in JSON format.

Available endpoints

http://localhost:5000/api/v1/ is the base URL for all endpoints:

HTTP method	endpoint	JSON args	description
