module: keycloak_component

|
short_description: Allows administration of Keycloak components using Keycloak API
|
|
|
|
version_added: 10.0.0
|
|
|
|
description:
|
|
- This module allows the administration of Keycloak components 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, C(admin-cli) and an
|
|
C(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/latest/rest-api/index.html).
|
|
Aliases are provided so camelCased versions can be used as well.
