**✨✨ MANTELO is a super small yet super powerful library for interacting with the Keycloak Admin API ✨✨**
> Mantelo [manˈtelo], from German "*Mantel*", from Late Latin "*mantum*" means "*cloak*" in Esperanto.
It stays always **fresh** and **complete** because it does not implement or wrap any endpoint.
Instead, it offers an object-oriented interface to the Keycloak ReSTful API. Acting as a wrapper
around the well-known [requests](https://requests.readthedocs.io/en/latest/) library and using
slumber under the hood, it abstracts all the boring stuff such as authentication (tokens and refresh
tokens), URL handling, serialization, and the processing of requests. This magic is made possible by
the excellent [slumber](https://slumber.readthedocs.io/) library.
Any endpoint your Keycloak supports, mantelo supports!

## 🚀 Why mantelo?
You may ask why using mantelo instead of writing your own requests wrapper, or another library such
as [python-keycloak](https://python-keycloak.readthedocs.io/en/latest/). Here are some
(non-exhaustive) arguments to help you make the right choice:
- mantelo only relies on 3 small packages.
- Contrary to other libraries such as python-keycloak, mantelo is always up-to-date and doesn't lack
any endpoints.
- mantelo makes your code look nice and object-oriented, instead of having long hard-coded URL strings everywhere.
- mantelo abstracts away authentication (and refresh tokens), which is always tricky to get right.
- mantelo gives you access to the exact URL that was called, and the `requests.Response` in case of error,
so debugging is easy.
- mantelo is flexible: you can tweak it easily if you need to.
## 🏁 Getting started
To get started, install the package:
```bash
pip install mantelo
```
Now, assuming you have a Keycloak Server running, what's left is to:
1. authenticate, see [🔐 Authenticate to Keycloak](#-authenticate-to-keycloak)
2. make calls, see [📡 Making calls](#-making-calls)
For a quick test drive, use the [docker-compose.yml](docker-compose.yml) included
in this repo and start a Keycloak server locally using `docker compose up`.
Open a Python REPL and type:
```python
from mantelo import KeycloakAdmin
c = KeycloakAdmin.from_username_password(
server_url="http://localhost:9090",
realm_name="master",
client_id="admin-cli",
username="admin",
password="admin",
)
# get the list of clients in realm "master"
c.clients.get()
# create a user
c.users.post({
"username": "test",
"enabled": True,
"credentials": [{"type": "password", "value": "test"}],
})
# get the user id
c.users.get(username="test")[0]["id"]
# ...
```
Here is the simplest example, assuming your Keycloak runs on `http://localhost:8080` and you have
setup the admin user with the password `admin`.
## 🔐 Authenticate to Keycloak
To authenticate to Keycloak, you can either use a username+password, or client credentials (client
ID+client secret, also known as service account).
The library takes care of fetching a token the first time you need it and keeping it fresh. By
default, it tries to use the refresh token (if available) and always guarantees the token is valid
for the next 30s.
**IMPORTANT** A client is meant to interact with a single realm, which can be different
from the realm used for authentication.
### Authenticating with username+password
Ensure your user has the right to interact with the endpoints you are interested in.
In doubt or for testing, you can either use the admin user (not recommended) or create
a user and assign it the `realm-management:realm-admin` role (full access).
The default client `admin-cli` can always be used for connection.
Here is how to connect to the default realm with the admin user and `admin-cli` client:
```python
from mantelo import KeycloakAdmin
client = KeycloakAdmin.from_username_password(
server_url="http://localhost:8080", # base Keycloak URL
realm_name="master",
# ↓↓ Authentication
client_id="admin-cli",
username="admin",
password="CHANGE-ME", # TODO
)
```
This client will be able to make calls only to the `master` realm.
If you want to authenticate to a realm that is different from the one
you want to query, use the argument `authentication_realm`:
```python
from mantelo import KeycloakAdmin
client = KeycloakAdmin.from_username_password(
server_url="http://localhost:8080", # base Keycloak URL
realm_name="my-realm", # realm for querying
# ↓↓ Authentication
authentication_realm_name="master", # realm for authentication only
client_id="admin-cli",
username="admin",
password="CHANGE-ME",
)
```
### Authenticating with client credentials (client ID + secret)
To authenticate via a client, the latter needs:
- to have "Client authentication" enabled,
- to support the `Service accounts roles` authentication flow,
- to have one or more service account roles granting access to Admin endpoints.
Go to your client's "Credentials" tab to find the client secret.
Here is how to connect with a client:
```python
from mantelo import KeycloakAdmin
client = KeycloakAdmin.from_client_credentials(
server_url="http://localhost:8080", # base Keycloak URL
realm_name="master",
# ↓↓ Authentication
client_id="my-client-name",
client_secret="59c3c211-2e56-4bb8-a07d-2961958f6185",
)
```
This client will be able to make calls only to the `master` realm.
If you want to authenticate to a realm that is different from the one
you want to query, use the argument `authentication_realm`:
```python
from mantelo import KeycloakAdmin
client = KeycloakAdmin.from_client_credentials(
server_url="http://localhost:8080", # base Keycloak URL
realm_name="my-realm", # realm for querying
# ↓↓ Authentication
authentication_realm_name="master", # realm for authentication only
client_id="my-client-name",
client_secret="59c3c211-2e56-4bb8-a07d-2961958f6185",
)
```
### Other ways of authenticating
The supported authentication methods should be enough. If you need more, a pull request or an issue
is welcome! But just in case, here are some ways to make it more complicated 😉.
To create a `KeycloakAdmin`, you only need a method that returns a token. For example, you can use
an existing token directly (not recommended, as tokens are short-lived):
```python
from mantelo.client import BearerAuth, KeycloakAdmin
KeycloakAdmin(
server_url="http://localhost:8080",
realm_name="master",
auth=BearerAuth(lambda: "my-token"),
)
```
If you want to go further, you can create your own `Connection` class (or extend the
`OpenidConnection`), and pass its `.token` method to the `BearerAuth`:
```python
from mantelo.client import BearerAuth, KeycloakAdmin
from mantelo.connection import Connection
class MyConnection(Connection):
def token(self):
return ""
connection = MyConnection()
KeycloakAdmin(
server_url="http://localhost:8080",
realm_name="master",
auth=BearerAuth(connection.token),
)
```
## 📡 Making calls
Once you have configured how to authenticate to Keycloak, the rest is easy-peasy.
mantelo **starts with the URL `/admin/realms/`** and constructs
the URL from there, depending on how you call the client.
The return value is the HTTP response content, parsed from JSON. In case of error, an
`HttpException` with access to the raw response is available (see [💀 Exceptions](#-exceptions)).
Query parameters can be passed as `kwargs` to `.get`, `.post`, etc.
`.post` and `.put` take the payload as first argument, or as the named argument `data`.
Here are some examples of URL mapping (`c` is the `KeycloakAdmin` object):
| call | URL |
| ------------------------------------------------------- | ----------------------------------------------------------------------------- |
| `c.users.get()` | `GET /admin/realms/{realm}/users` |
| `c.users.get(search="foo bar")` | `GET /admin/realms/{realm}/users?search=foo+bar` |
| `c.users.count.get()` | `GET /admin/realms/{realm}/users/count` |
| `c.users("725209cd-9076-417b-a404-149a3fb8e35b").get()` | `GET /admin/realms/{realm}/users/725209cd-9076-417b-a404-149a3fb8e35b` |
| `c.users.post({"username": ...})` | `POST /admin/realms/{realm}/users/725209cd-9076-417b-a404-149a3fb8e35b` |
| `c.users.post(foo=1, data={"username": ...})` | `POST /admin/realms/{realm}/users/725209cd-9076-417b-a404-149a3fb8e35b?foo=1` |
Here are some examples:
```python
>> client.users.get()
[{'id': '8d83ecda-766d-4382-8f3a-4c5ac1962961',
'username': 'constant',
'firstName': 'Jasper',
'lastName': 'Fforde',
'email': '[email protected]',
'emailVerified': True,
'createdTimestamp': 1710273159287,
'enabled': True,
'totp': False,
'disableableCredentialTypes': [],
'requiredActions': [],
'notBefore': 0,
'access': {'manageGroupMembership': True,
'view': True,
'mapRoles': True,
'impersonate': False,
'manage': True}}]
>> client.users.count.get()
2
>> c.clients.get()
...
HttpException: (403, {'error': 'unknown_error', 'error_description': 'For more on this error consult the server log at the debug level.'}, 'http://localhost:9090/admin/realms/orwell/clients', )
```
## 💀 Exceptions
If the server returns a 401 Unauthorized during the _authentication_ process, mantelo will raise an
`AuthenticationException` with the `error` and `errorDescription` from Keycloak. All other HTTP
exceptions are instances of `HttpException`.
Here are some examples:
```python
# Using an inexistant client
AuthenticationException(
error='invalid_client',
error_description='Invalid client or Invalid client credentials'
response='',
)
# Trying to access an endpoint without the proper permissions
HttpException(
status_code=403,
json={'error': 'unknown_error', 'error_description': 'For more on this error consult the server log at the debug level.'},
url='http://localhost:9090/admin/realms/orwell/clients',
response='',
)
```
