module: keycloak_role
short_description: Allows administration of Keycloak roles via Keycloak API
version_added: 3.4.0
description:
- This module allows you to add, remove or modify Keycloak roles via 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.
attributes:
check_mode:
support: full
diff_mode:
support: full
options:
state:
description:
- State of the role.
- On V(present), the role will be created if it does not yet exist, or updated with the parameters you provide.
- On V(absent), the role will be removed if it exists.
default: 'present'
type: str
choices:
- present
- absent
name:
type: str
required: true
description:
- Name of the role.
- This parameter is required.
description:
type: str
description:
- The role description.
realm:
type: str
description:
- The Keycloak realm under which this role resides.
default: 'master'
client_id:
type: str
description:
- If the role is a client role, the client id under which it resides.
- If this parameter is absent, the role is considered a realm role.
attributes:
type: dict
description:
- A dict of key/value pairs to set as custom attributes for the role.
- Values may be single values (e.g. a string) or a list of strings.
composite:
description:
- If V(true), the role is a composition of other realm and/or client role.
default: false
type: bool
version_added: 7.1.0
composites:
description:
- List of roles to include to the composite realm role.
- If the composite role is a client role, the C(clientId) (not ID of the client) must be specified.
default: []
type: list
elements: dict
version_added: 7.1.0
suboptions:
name:
description:
- Name of the role. This can be the name of a REALM role or a client role.
type: str
required: true
client_id:
description:
- Client ID if the role is a client role. Do not include this option for a REALM role.
- Use the client ID you can see in the Keycloak console, not the technical ID of the client.
type: str
required: false
aliases:
- clientId
state:
description:
- Create the composite if present, remove it if absent.
type: str
choices:
- present
