module: keycloak_realm_info

short_description: Allows obtaining Keycloak realm public information via Keycloak API

version_added: 4.3.0

description:
    - This module allows you to get Keycloak realm public information via the Keycloak REST API.

    - 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).

    - Attributes are multi-valued in the Keycloak API. All attributes are lists of individual values and will
      be returned that way by this module. You may pass single values for attributes when calling the module,
      and this will be translated into a list suitable for the API.

options:
    auth_keycloak_url:
        description:
            - URL to the Keycloak instance.
        type: str
        required: true
        aliases:
          - url
    validate_certs:
        description:
            - Verify TLS certificates (do not disable this in production).
        type: bool
        default: yes

    realm:
        type: str
        description:

        default: 'master'
