Access Control¶
Access Control of Airflow Webserver UI is handled by Flask AppBuilder (FAB). Please read its related security document regarding its security model.
Default Roles¶
Airflow ships with a set of roles by default: Admin, User, Op, Viewer, and Public.
Only Admin users could configure/alter the permissions for other roles. But it is not recommended
that Admin users alter these default roles in any way by removing
or adding permissions to these roles.
Admin¶
Admin users have all possible permissions, including granting or revoking permissions from
other users.
Public¶
Public users (anonymous) don’t have any permissions.
Viewer¶
Viewer users have limited viewer permissions
VIEWER_PERMISSIONS = [
(permissions.ACTION_CAN_READ, permissions.RESOURCE_AUDIT_LOG),
(permissions.ACTION_CAN_READ, permissions.RESOURCE_DAG),
(permissions.ACTION_CAN_READ, permissions.RESOURCE_DAG_DEPENDENCIES),

on limited web views.
User¶
User users have Viewer permissions plus additional user permissions
USER_PERMISSIONS = [
(permissions.ACTION_CAN_EDIT, permissions.RESOURCE_DAG),
(permissions.ACTION_CAN_DELETE, permissions.RESOURCE_DAG),
(permissions.ACTION_CAN_CREATE, permissions.RESOURCE_TASK_INSTANCE),

(permissions.ACTION_CAN_EDIT, permissions.RESOURCE_DAG_RUN),
(permissions.ACTION_CAN_DELETE, permissions.RESOURCE_DAG_RUN),
]
on User web views which is the same as Viewer web views.
Op¶
Op users have User permissions plus additional op permissions
OP_PERMISSIONS = [
(permissions.ACTION_CAN_READ, permissions.RESOURCE_CONFIG),
(permissions.ACTION_CAN_ACCESS_MENU, permissions.RESOURCE_ADMIN_MENU),
(permissions.ACTION_CAN_ACCESS_MENU, permissions.RESOURCE_CONNECTION),

(permissions.ACTION_CAN_EDIT, permissions.RESOURCE_VARIABLE),
(permissions.ACTION_CAN_DELETE, permissions.RESOURCE_VARIABLE),
(permissions.ACTION_CAN_DELETE, permissions.RESOURCE_XCOM),
]
on User web views.
Custom Roles¶
DAG Level Role¶
Admin can create a set of roles which are only allowed to view a certain set of dags. This is called DAG level access. Each dag defined in the dag model table
is treated as a View which has two permissions associated with it (can_read and can_edit. can_dag_read and can_dag_edit are deprecated since 2.0.0).
There is a special view called DAGs (it was called all_dags in versions 1.10.*) which
allows the role to access all the dags. The default Admin, Viewer, User, Op roles can all access DAGs view.
The image shows the creation of a role which can only write to
example_python_operator. You can also create roles via the CLI
using the airflow roles create command, e.g.:
airflow roles create Role1 Role2
And we could assign the given role to a new user using the airflow
users add-role CLI command.
Permissions¶
Resource-Based permissions¶
Starting with version 2.0, permissions are based on individual resources and a small subset of actions on those
resources. Resources match standard Airflow concepts, such as Dag, DagRun, Task, and
Connection. Actions include can_create, can_read, can_edit, and can_delete.
Permissions (each consistent of a resource + action pair) are then added to roles.
To access an endpoint, the user needs all permissions assigned to that endpoint
There are five default roles: Public, Viewer, User, Op, and Admin. Each one has the permissions of the preceding role, as well as additional permissions.
DAG-level permissions¶
For DAG-level permissions exclusively, access can be controlled at the level of all DAGs or individual DAG objects. This includes DAGs.can_create, DAGs.can_read, DAGs.can_edit, and DAGs.can_delete. When these permissions are listed, access is granted to users who either have the listed permission or the same permission for the specific DAG being acted upon. For individual DAGs, the resource name is DAG: + the DAG ID.
For example, if a user is trying to view DAG information for the example_dag_id, and the endpoint requires DAGs.can_read access, access will be granted if the user has either DAGs.can_read or DAG:example_dag_id.can_read access.
