Written by
Updated at October 30, 2024

To grant a user, group, or service account access to an image, assign a role for it.

Assigning a role

  1. In the management console, select the folder where the image is located.
  2. Select Compute Cloud.
  3. In the left-hand panel, select Images.
  4. Select the image you need.
  5. Go to the Access bindings tab.
  6. Click Assign bindings.
  7. In the window that opens, select the group, user, or service account to grant access to the image.
  8. Click Add role and select the required role.
  9. Click Save.

If you do not 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.

  1. See the CLI command description for assigning a role for an image:

    yc compute image add-access-binding --help

  2. Get a list of images in the default folder:

    yc compute image list

  3. View the list of roles already assigned for the resource:

    yc compute image list-access-bindings <image_ID>

  4. Assign the role using the command:

    • To a user:

      yc compute image add-access-binding <image_ID> \
  --user-account-id <user_ID> \
  --role <role>

      Where:

      • --user-account-id: User ID. To assign a role to all authenticated users, use the --all-authenticated-users flag.
      • --role: Role to assign.

    • To a service account:

      yc compute image add-access-binding <image_ID> \
  --service-account-id <service_account_ID> \
  --role <role>

      Where:

Terraform allows you to quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. Configuration files store the infrastructure description in the HashiCorp Configuration Language (HCL). Terraform and its providers are distributed under the Business Source License.

For more information about the provider resources, see the documentation on the Terraform website or the mirror.

If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

If you don't have Terraform, install it and configure the Yandex Cloud provider.

To assign a role for an image using Terraform:

  1. In the Terraform configuration file, describe the parameters of the resources you want to create:

    resource "yandex_compute_image_iam_binding" "sa-access" {
  image_id = "<image_ID>"
  role     = "<role>"
  members  = ["<subject_type>:<subject_ID>","<subject_type>:<subject_ID>"]
}

    Where:

    • image_id: Image ID.
    • role: Role to assign.
    • members: List of types and IDs of subjects the roles are assigned to. Specify it as userAccount:<user_ID> or serviceAccount:<service_account_ID>.

    For more information about the yandex_compute_image_iam_binding resource parameters, see the provider documentation.

  2. Create resources:

    1. In the terminal, change to the folder where you edited the configuration file.

    2. Make sure the configuration file is correct using the command:

      terraform validate

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.

    3. Run the command:

      terraform plan

      The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.

    4. Apply the configuration changes:

      terraform apply

    5. Confirm the changes: type yes in the terminal and press Enter.

    Terraform will create all the required resources. You can check the new resources using the management console or this CLI command:

    yc compute image list-access-bindings <image_ID>

To assign a role, use the updateAccessBindings REST API method for the Image resource or the ImageService/UpdateAccessBindings gRPC API call. In the request body, set the action property to ADD and specify the user type and ID in the subject property.

Assigning multiple roles

  1. In the management console, select the folder where the image is located.
  2. Select Compute Cloud.
  3. In the left-hand panel, select Images.
  4. Select the image you need.
  5. Go to the Access bindings tab.
  6. Click Assign bindings.
  7. In the window that opens, select the group, user, or service account to grant access to the image.
  8. Click Add role and select the required role.
  9. To add another role, click Add role.
  10. Click Save.

If you do not 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.

You can assign multiple roles using the set-access-bindings command.

Alert

The set-access-bindings command completely rewrites the access permissions for the resource. All current resource roles will be deleted.

  1. Make sure the resource has no roles assigned that you would not want to lose:

    yc compute image list-access-bindings <image_ID>

  2. See the CLI command description for assigning roles for an image:

    yc compute image set-access-bindings --help

  3. Assign roles:

    yc compute image set-access-bindings <image_ID> \
  --access-binding role=<role>,subject=<subject_type>:<subject_ID> \
  --access-binding role=<role>,subject=<subject_type>:<subject_ID>

    Where:

    • --access-binding: Parameters for setting access permissions:

      • role: Role to assign.
      • subject: Type and ID of the subject getting the role.

    For example, assign roles to multiple users and a service account:

    yc compute image set-access-bindings my-image \
  --access-binding role=editor,subject=userAccount:gfei8n54hmfh********
  --access-binding role=viewer,subject=userAccount:helj89sfj80a********
  --access-binding role=editor,subject=serviceAccount:ajel6l0jcb9s********

  role     = "<role_1>"
  members  = ["<subject_type>:<subject_ID>"]
}

resource "yandex_compute_image_iam_binding" "role-2" {
  image_id = "<image_ID>"
  role     = "<role_2>"
  members  = ["<subject_type>:<subject_ID>"]
}

    Where:

    • image_id: Image ID.
    • role: Role to assign.
    • members: List of types and IDs of subjects the roles are assigned to. Specify it as userAccount:<user_ID> or serviceAccount:<service_account_ID>.

    5. Confirm the changes: type yes in the terminal and press Enter.

    You can check the updates using the management console or this CLI command:

    yc compute image list-access-bindings <image_ID>

To assign roles for a resource, use the setAccessBindings REST API method for the Image resource or the ImageService/SetAccessBindings gRPC API call.

Alert

The setAccessBindings method and the ImageService/SetAccessBindings call completely overwrite access permissions for the resource. All current resource roles will be deleted.

Revoking a role

  1. In the management console, select the folder where the image is located.
  2. Select Compute Cloud.
  3. In the left-hand panel, select Images.
  4. Select the image you need.
  5. Go to the Access bindings tab.
  6. In the line with the user you need, click and select Edit roles.
  7. Next to the role, click .
  8. Click Save.

If you do not 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.

  1. See the CLI command description for revoking a role for an image:

    yc compute image remove-access-binding --help

  2. View the roles and assignees for the resource:

    yc compute image list-access-bindings <image_ID>

  3. To revoke access permissions, run this command:

    yc compute image remove-access-binding <image_ID> \
  --role=<role> \
  --subject=<subject_type>:<subject_ID> \

    Where:

    • --role: ID of the role to revoke.
    • --subject: Type and ID of the subject getting the role.

    For example, to revoke the viewer role for an image from a user with the ajel6l0jcb9s******** ID:

    yc compute image remove-access-binding my-image \
  --role viewer \
  --subject userAccount:ajel6l0jcb9s********
