module: keycloak_realm

short_description: Allows administration of Keycloak realm using Keycloak API

version_added: 3.0.0

description:
  - This module allows the administration of Keycloak realm using the Keycloak REST API. It requires access to the REST API
    using OpenID Connect; the user connecting and the realm being used must have the requisite access rights. In a default
    Keycloak installation, admin-cli and an admin user would work, as would a separate realm definition with the scope tailored
    to your needs and a user having the expected roles.
  - The names of module options are snake_cased versions of the camelCase ones found in the Keycloak API and its documentation
    at U(https://www.keycloak.org/docs-api/8.0/rest-api/index.html). Aliases are provided so camelCased versions can be used
    as well.
  - The Keycloak API does not always sanity check inputs, for example you can set SAML-specific settings on an OpenID Connect
    client for instance and also the other way around. B(Be careful). If you do not specify a setting, usually a sensible
    default is chosen.
