## Prerequisites

Configure and install keycloak server by following [Keycloak Installation Guide](https://www.keycloak.org/docs/latest/server_installation/#installing-the-software).
For a quick installation, docker-compose reference configs are also available on the [Keycloak GitHub](https://github.com/keycloak/keycloak-containers/tree/main/docker-compose-examples).

Окрім звичайних типів, таких як `str`, `int`, `float`, та ін. Ви можете використовувати складніші типи, які наслідують `str`.

Щоб побачити всі доступні варіанти, ознайомтеся з оглядом <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">типів у Pydantic</a>. Деякі приклади будуть у наступних розділах.

Наприклад, у моделі `Image` є поле `url`, тому ми можемо оголосити його як `HttpUrl` від Pydantic замість `str`:

            <p>
            We check the binary compatibility by comparing the current code’s binary interfaces
            against THE LATEST VERSION WHICH IS RELEASED FROM RELEASE BRANCH (from `released-version.json` on this branch)
            AND LOWER THAN CURRENT BASE VERSION (from `version.txt` on this branch).

Apart from normal singular types like `str`, `int`, `float`, etc. you can use more complex singular types that inherit from `str`.
