Yandex.Cloud Connection
=======================

The Yandex.Cloud connection type enables the authentication in Yandex.Cloud services.

Configuring the Connection
--------------------------

Service account auth JSON
    JSON object as a string.

    Example: ``{"id": "...", "service_account_id": "...", "private_key": "..."}``

Service account auth JSON file path
    Path to the file containing service account auth JSON.

    Example: ``/home/airflow/authorized_key.json``

OAuth Token
    User account OAuth token as a string.

    Example: ``y3_Vd3eub7w9bIut67GHeL345gfb5GAnd3dZnf08FR1vjeUFve7Yi8hGvc``

SSH public key (optional)
    The key will be placed to all created Compute nodes, allowing you to have a root shell there.

Folder ID (optional)
    A folder is an entity to separate different projects within the cloud.

    If specified, this ID will be used by default when creating nodes and clusters.

    See `this guide <https://cloud.yandex.com/docs/resource-manager/operations/folder/get-id>`__ for details.

Endpoint (optional)
    Use this setting to configure your API endpoint.

    Leave blank to use default `endpoints <https://cloud.yandex.com/docs/api-design-guide/concepts/endpoints>`__.

Default Connection IDs
----------------------

All hooks and operators related to Yandex.Cloud use the ``yandexcloud_default`` connection by default.

Authenticating to Yandex.Cloud
------------------------------

Using authorized keys to authorize as a service account
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Before you start, make sure you have `created <https://cloud.yandex.com/docs/iam/operations/sa/create>`__
a Yandex Cloud `service account <https://cloud.yandex.com/docs/iam/concepts/users/service-accounts>`__.

First, you need to create an `authorized key <https://cloud.yandex.com/docs/iam/concepts/authorization/key>`__
for your service account and save the generated JSON file with both public and private key parts.

Then, you need to specify the key in the ``Service account auth JSON`` field.

Alternatively, you can specify the path to the JSON file in the ``Service account auth JSON file path`` field.

Using an OAuth token to authorize as a user account
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First, you need to create
an `OAuth token <https://cloud.yandex.com/docs/iam/concepts/authorization/oauth-token>`__ for your user account.
Your token will look like this: ``y3_Vd3eub7w9bIut67GHeL345gfb5GAnd3dZnf08FR1vjeUFve7Yi8hGvc``.

Then you need to specify your token in the ``OAuth Token`` field.

Using metadata service
~~~~~~~~~~~~~~~~~~~~~~

If you do not specify any credentials, the connection will attempt to use
the `metadata service <https://cloud.yandex.com/docs/compute/concepts/vm-metadata>`__ for authentication.

To do this, you need to `link <https://cloud.yandex.com/docs/compute/operations/vm-connect/auth-inside-vm>`__
your service account with your VM.
