ARA API Server authentication and security¶
The API server ships with a default configuration that emphasizes simplicity to let users get started quickly.
- A random SECRET_KEY will be generated once if none are supplied
- No users are created
- API authentication and permissions are not enabled
- ALLOWED_HOSTS and CORS_ORIGIN_WHITELIST are configured for use on localhost
These default settings can be configured according to the requirements of your deployments.
Setting a custom secret key¶
By default, the API server randomly generates a token for the ARA_SECRET_KEY setting if none have been supplied by the user.
This value is persisted in the server configuration file in order to prevent the key from changing on every instanciation of the server.
The default location for the server configuration file is
You can provide a custom secret key by supplying the
environment variable or by specifying the
SECRET_KEY setting in your server
The API server leverages Django’s user management but doesn’t create any user by default.
Creating users does not enable authentication on the API. In order to make authentication required for using the API, see Enabling authentication for read or write access.
In order to create users, you’ll need to create a superuser account before running the API server:
$ ara-manage createsuperuser --username=joe --email@example.com Password: Password (again): Superuser created successfully.
If you ever need to reset the password of a superuser account, this can be done with the “changepassword” command:
$ ara-manage changepassword joe Changing password for user 'joe' Password: Password (again): Password changed successfully for user 'joe'
Once the superuser has been created, make sure the API server is started and then login to the Django web administrative interface using the credentials you just set up.
By default, you can start the API server with
ara-manage runserver and
access the admin interface at
Log in to the admin interface:

And from here, you can manage existing users or create new ones:
Enabling authentication for read or write access¶
Once you have created your users, you can enable authentication against the API for read (ex: GET) and write (ex: DELETE, POST, PATCH) requests.
This is done with the two following configuration options:
These settings are global and are effective for all API endpoints.
Setting up authentication for the Ansible plugins¶
The callback plugin used to record playbooks as well as the
action plugin will need to authenticate against the API if authentication is
enabled and required.
You can specify the necessary credentials through the
ARA_API_PASSWORD environment variables or through your
[defaults] # ... [ara] api_client = http api_server = http://api.example.org api_username = ara api_password = password
Using authentication with the API clients¶
To instanciate an authenticated client with the built-in basic HTTP authentication provided by Django:
from ara.clients.utils import get_client client = get_client( client="http", endpoint="http://api.example.org", username="ara", password="password" )
If you have a custom authentication that is supported by the
library, you can also pass the relevant
auth object directly to the client:
from ara.clients.http import AraHttpClient from requests_oauthlib import OAuth1 auth = OAuth1( "YOUR_APP_KEY", "YOUR_APP_SECRET", "USER_OAUTH_TOKEN", "USER_OAUTH_TOKEN_SECRET" ) client = AraHttpClient(endpoint="http://api.example.org", auth=auth)
Managing hosts allowed to serve the API¶
By default, ARA_ALLOWED_HOSTS authorizes
127.0.0.1 to serve requests for the API server.
In order to host an instance of the API server on another domain, the domain must be part of this list or the application server will deny any requests sent to it.
Managing CORS (cross-origin resource sharing)¶
The whitelist must contain the domain names where you plan on hosting instances of ara-web.
