A plugin to Apache Airflow (Documentation: https://airflow.apache.org/, Source Code: https://github.com/apache/airflow) to provide an interface where you can add a PasswordUser to Airflow and manage

If you are using the Airflow versions 1.10.x and higher then this plugin is useful only when RBAC feature is disabled. You can check the rbac setting in airflow.cfg config file under webserver category. When RBAC feature is enabled you can manage users directly from the Security menu provided by Airflow UI.

Note: Once you enable the RBAC support, it will create new set of Database Tables. So, you need to manually migrate your existing users from users table to the new table ab_users. While migrating you need to specify the role for each user. Please check Create User for more details.

1. Copy the user_management_plugin.py file into the Airflow Plugins directory

   • The Airflow Plugins Directory is defined in the airflow.cfg file as the variable "plugins_folder"

   • The Airflow Plugins Directory is, by default, ${AIRFLOW_HOME}/plugins

   • You may have to create the Airflow Plugins Directory folder as it is not created by default

   • quick way of doing this:

       $ cd {AIRFLOW_PLUGINS_FOLDER}
       $ wget https://raw.githubusercontent.com/teamclairvoyant/airflow-user-management-plugin/master/plugins/user_management_plugin.py

2. Restart the Airflow Services

3. Your done!

Once you've restarted the Web Application, you should now see a new Tab: Admin -> User Management. From here, you can create new users and update or delete existing ones.

• This plugin requires that you already have one Airflow user setup. Please refer http://airflow.apache.org/security.html#password to know how to setup Airflow user.

• Only Admin Users can create/delete other users.

• Add the following configuration in the airflow.cfg file for versions < 2.0

    [user_management_plugin]
    #provide comma separated list of admin users
    #Ex: admin_users=admin,airflow
    admin_users=airflow
  

• For versions >= 2.0 you need to make sure the superuser attribute is set to True for the Airflow User. Please refer http://airflow.apache.org/_api/airflow/models/index.html#airflow.models.User for details.

Note: superuser flag in the create/edit user form will be effective only from version >= 2.0
