.. py:class:: EnvironmentVariablesBackend

   Bases: :py:obj:`airflow.secrets.BaseSecretsBackend`

   Retrieves Connection object and Variable from environment variable.

   .. py:method:: get_conn_uri(self, conn_id)

      Return URI representation of Connection conn_id
      :param conn_id: the connection id
      :return: deserialized Connection


   .. py:method:: get_conn_value(self, conn_id)

      Retrieve from Secrets Backend a string value representing the Connection object.

      If the client your secrets backend uses already returns a python dict, you should override
      ``get_connection`` instead.

      :param conn_id: connection id


   .. py:method:: get_variable(self, key)

      Get Airflow Variable from Environment Variable

      :param key: Variable Key
      :return: Variable Value
