module: keycloak_client_rolemapping
short_description: Allows administration of Keycloak client_rolemapping with the Keycloak API
version_added: 3.5.0
description:
- This module allows you to add, remove or modify Keycloak client_rolemapping with the Keycloak REST API.
It requires access to the REST API via OpenID Connect; the user connecting and the client 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 client 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).
- 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.
- When updating a client_rolemapping, where possible provide the role ID to the module. This removes a lookup
to the API to translate the name into the role ID.

options:
state:
description:
- State of the client_rolemapping.
- On V(present), the client_rolemapping will be created if it does not yet exist, or updated with the parameters you provide.
- On V(absent), the client_rolemapping will be removed if it exists.
default: 'present'

choices:
- present
- absent
realm:
type: str
description:
- They Keycloak realm under which this role_representation resides.
default: 'master'
group_name:
type: str
description:
- Name of the group to be mapped.
- This parameter is required (can be replaced by gid for less API call).
gid:
type: str
description:
- Id of the group to be mapped.
- This parameter is not required for updating or deleting the rolemapping but
providing it will reduce the number of API calls required.
client_id:
type: str
description:
- Name of the client to be mapped (different than O(cid)).
- This parameter is required (can be replaced by cid for less API call).
cid:
type: str
description:
- Id of the client to be mapped.
- This parameter is not required for updating or deleting the rolemapping but
providing it will reduce the number of API calls required.
roles:
description:
- Roles to be mapped to the group.
type: list
elements: dict
suboptions:
name:
type: str
description:
- Name of the role_representation.
- This parameter is required only when creating or updating the role_representation.
id:
type: str
description:
- The unique identifier for this role_representation.
- This parameter is not required for updating or deleting a role_representation but
providing it will reduce the number of API calls required.
