Getting a service account ID token

If you do not have the Yandex Cloud (CLI) command line interface yet, install and initialize it.

The folder specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.

1. View the description of the command for creating an ID token:

   yc iam create-id-token --help
   

2. Get the ID of the service account to use for authentication in the external system:

   yc iam service-account list
   

   Result:

   +----------------------+--------------+--------+---------------------+-----------------------+
   |          ID          |     NAME     | LABELS |     CREATED AT      | LAST AUTHENTICATED AT |
   +----------------------+--------------+--------+---------------------+-----------------------+
   | ajeg2b2et02f******** | my-robot     |        | 2024-09-08 18:59:45 | 2025-02-18 10:10:00   |
   | ajegtlf2q28a******** | account-name |        | 2023-06-27 16:18:18 | 2025-02-18 10:20:00   |
   +----------------------+--------------+--------+---------------------+-----------------------+
   

3. Get an ID token for the service account:

   yc iam create-id-token \
     --subject-id <service_account_ID> \
     --audience <resource>
   

   Where:

   • --subject-id: ID of the service account to create an ID token for.
   • --audience: Target resource for the token. This is an optional parameter. If left unspecified, this value defaults to the service account ID specified in the subject-id parameter.

   In response, the command will output the body of the created service account ID token to the standard output stream (STDOUT).
