New module: keycloak_group (#35637)
* Initial implementation of groups module. Not all parameters are supported, yet. * Clarify read-only status of realmRoles, clientRoles and access attributes * Fix testing failures * Fix additional style issues. * Minor updates and fixes after review feedback * Simplify return values after feedback This removes the 'proposed' and 'end_state' return values, replacing them instead with just 'group'. 'group' is the representation of the group after the module completes. Also update the dates, and the Ansible version * Corrections after module validation * Further documentation updates after feedback Minor whitespace adjustments also * Add delegate_to: localhost stanzas to examplespull/55115/head

module: keycloak_group
|
||||
|
||||
short_description: Allows administration of Keycloak groups via Keycloak API
|
||||
|
||||
description:
|
||||
- This module allows you to add, remove or modify Keycloak groups 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(http://www.keycloak.org/docs-api/3.3/rest-api/).
|
||||
|
||||
- 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 group, where possible provide the group ID to the module. This removes a lookup
|
||||
to the API to translate the name into the group ID.
|
||||
|
||||
version_added: "2.8"
|
||||
|
||||
options:
|
||||
state:
|
||||
description:
|
||||
- State of the group.
|
||||
- On C(present), the group will be created if it does not yet exist, or updated with the parameters you provide.
|
||||
- On C(absent), the group will be removed if it exists.
|
||||
required: true
|
||||
default: 'present'
|

type: str
|
||||
choices:
|
||||
- present
|
||||
- absent
|
||||
|
||||
name:
|
||||
type: str
|
||||
description:
|
||||
- Name of the group.
|
||||
- This parameter is required only when creating or updating the group.
|
||||
|
||||
realm:
|
||||
type: str
|
||||
description:
|
||||
- They Keycloak realm under which this group resides.
|
||||
default: 'master'
|
||||
|
||||
id:
|
||||
type: str
|
||||
description:
|
||||
- The unique identifier for this group.
|
||||
- This parameter is not required for updating or deleting a group but
|
||||
providing it will reduce the number of API calls required.
|
||||
|
||||
attributes:
|
||||
type: dict
|
||||
description:
|
||||
- A dict of key/value pairs to set as custom attributes for the group.
|
||||
- Values may be single values (e.g. a string) or a list of strings.
|
||||
|
||||
notes:
|
||||
- Presently, the I(realmRoles), I(clientRoles) and I(access) attributes returned by the Keycloak API
|
||||
are read-only for groups. This limitation will be removed in a later version of this module.
