Configuring and using IAM authentication | ||
---------------------------------------- | ||
|
||
.. warning:: | ||
This functionality requires ``gcloud`` command (Google Cloud SDK) must be `installed | ||
<https://cloud.google.com/sdk/docs/install>`_ on the Airflow worker. | ||
|
||
.. warning:: | ||
IAM authentication working only for Google Service Accounts. | ||
|
||
Configure Service Accounts on Google Cloud IAM side | ||
""""""""""""""""""""""""""""""""""""""""""""""""""" | ||
|
||
For connecting via IAM you need to use Service Account. It can be the same service account which you use for | ||
the ``gcloud`` authentication or an another account. If you decide to use a different account then this | ||
account should be impersonated from the account which used for ``gcloud`` authentication and granted | ||
a ``Service Account Token Creator`` role. More information how to grant a role `here | ||
<https://cloud.google.com/iam/docs/manage-access-service-accounts?hl=en&_gl=1*3bsv5i*_ga*NDY4NDIyNTcxLjE3MjkxNzQ4MTM.*_ga_WH2QY8WWF5*MTcyOTE5MzU1OS4yLjEuMTcyOTE5NTM0My4wLjAuMA..#single-role>`_. | ||
|
||
Also the Service Account should be configured for working with IAM. | ||
Here are links describing what should be done before the start: | ||
`PostgreSQL<https://cloud.google.com/sql/docs/postgres/iam-logins#before_you_begin>`_ and | ||
`MySQL<https://cloud.google.com/sql/docs/mysql/iam-logins#before_you_begin>`_. | ||
|
||
Configure ``gcpcloudsql`` connection with IAM enabling | ||
"""""""""""""""""""""""""""""""""""""""""""""""""""""" | ||
|
||
For using IAM you need to enable ``"use_iam": "True"`` in the ``extra`` field. And specify IAM account in this format | ||
``USERNAME@PROJECT_ID.iam.gserviceaccount.com`` in ``login`` field and empty string in the ``password`` field. | ||
|
||
For example: | ||
|
||
.. exampleinclude:: /../../providers/tests/system/google/cloud/cloud_sql/example_cloud_sql_query_iam.py | ||
:language: python | ||
