Assigning roles to a service account
This section describes how to assign a role to a service account for a resource. To assign another user a role to a service account like to a resource, follow the instructions in Setting up access rights for service accounts.
A service account can only be assigned roles for the resources of the cloud that the service account belongs to.
In the management console, you can assign a service account a role only for the folders that are located in the same folder as the cloud where the service account was created. To assign it a role for another resource, use the CLI or API.
To assign the viewer role to a service account for the folder:
- In the management console, open the page of the folder to assign the role for.
- Go to Access bindings in folder (the Access bindings button in the left panel).
- Switch the Inherited roles option to on so that the list shows service accounts that don't belong to the current folder.
- Click next to the name of the service account.
- Click Edit roles.
- Click Add role and select the role you'd like to add.
- Click Save.
If you don't have the Yandex Cloud command line interface yet, install and initialize it.
The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name
or --folder-id
parameter.
To assign the service account a role for a resource, run:
yc <service-name> <resource> add-access-binding <resource-name>|<resource-id> \
--role <role-id> \
--subject serviceAccount:<service-account-id>
Where:
<service-name>
: The name of the service whose resource a role is assigned for (for example,resource-manager
).<resource>
: The resource category, for example,cloud
.<resource-name>
: The name of the resource. You can specify a resource by its name or ID.<resource-id>
: The resource ID.<role-id>
: The role ID, for example,resource-manager.clouds.owner
.<service-account-id>
: The identifier of the service account assigned the role.
For example, to assign the viewer
role to a service account for the my-folder
folder:
-
Find out the service account ID by its name:
yc iam service-account get my-robot
Result:
id: aje6o61dvog2h6g9a33s folder_id: b1gvmob95yysaplct532 created_at: "2018-10-15T18:01:25Z" name: my-robot
If you don't know the name of the service account, get a list of service accounts with their IDs:
yc iam service-account list
Result:
+----------------------+------------------+-----------------+ | ID | NAME | DESCRIPTION | +----------------------+------------------+-----------------+ | aje6o61dvog2h6g9a33s | my-robot | my description | +----------------------+------------------+-----------------+
-
Assign a role to the
my-robot
service account using its ID:yc resource-manager folder add-access-binding my-folder \ --role viewer \ --subject serviceAccount:aje6o61dvog2h6g9a33s
-
Get the ID of the folder with service accounts.
-
Get a list of folder service accounts to find out their IDs:
export FOLDER_ID=b1gvmob95yysaplct532 export IAM_TOKEN=CggaATEVAgA... curl -H "Authorization: Bearer ${IAM_TOKEN}" \ "https://iam.api.cloud.yandex.net/iam/v1/serviceAccounts?folderId=${FOLDER_ID}"
Result:
{ "serviceAccounts": [ { "id": "ajebqtreob2dpblin8pe", "folderId": "b1gvmob95yysaplct532", "createdAt": "2018-10-18T13:42:40Z", "name": "my-robot", "description": "my description" } ] }
-

body.json
file. Set theaction
property toADD
and specify theserviceAccount
type and service account ID in thesubject
property:body.json:
{ "accessBindingDeltas": [{ "action": "ADD", "accessBinding": { "roleId": "editor", "subject": { "id": "ajebqtreob2dpblin8pe", "type": "serviceAccount" } } } ] }
