See https://cloud.google.com/iam/docs/managing-policies for details of policy role and member types.

POSITIONAL ARGUMENTS

Backup resource - The Cloud Spanner backup to which to add the IAM policy binding. The arguments in this group can be used to specify the attributes of this resource. (NOTE) Some attributes are not given arguments in this group but can be set in other ways.

To set the project attribute:

• provide the argument backup on the command line with a fully specified name;
• provide the argument --project on the command line;
• set the property core/project.

This must be specified.

BACKUP

ID of the backup or fully qualified identifier for the backup.

To set the backup attribute:

• provide the argument backup on the command line.

This positional argument must be specified if any of the other arguments in this group are specified.

--instance=INSTANCE

The name of the Cloud Spanner instance. To set the instance attribute:

• provide the argument backup on the command line with a fully specified name;
• provide the argument --instance on the command line;
• set the property spanner/instance.

REQUIRED FLAGS

--member=PRINCIPAL

The principal to add the binding for. Should be of the form user|group|serviceAccount:email or domain:domain.

Examples: user:[e-mail], group:[e-mail], serviceAccount:[e-mail], or domain:example.domain.com.

Some resources also accept the following special values:

• allUsers - Special identifier that represents anyone who is on the internet, with or without a Google account.
• allAuthenticatedUsers - Special identifier that represents anyone who is authenticated with a Google account or a service account.

--role=ROLE

Role name to assign to the principal. The role name is the complete path of a predefined role, such as roles/logging.viewer, or the role ID for a custom role, such as organizations/{ORGANIZATION_ID}/roles/logging.viewer.

OPTIONAL FLAGS

At most one of these can be specified:

--condition=[KEY=VALUE,…]

A condition to include in the binding. When the condition is explicitly specified as None (--condition=None), a binding without a condition is added. When the condition is specified and is not None, --role cannot be a basic role. Basic roles are roles/editor, roles/owner, and roles/viewer. For more on conditions, refer to the conditions overview guide: https://cloud.google.com/iam/docs/conditions-overview

When using the --condition flag, include the following key-value pairs:

expression

(Required) Condition expression that evaluates to True or False. This uses a subset of Common Expression Language syntax.

If the condition expression includes a comma, use a different delimiter to separate the key-value pairs. Specify the delimiter before listing the key-value pairs. For example, to specify a colon (:) as the delimiter, do the following: --condition=^:^title=TITLE:expression=EXPRESSION. For more information, see https://cloud.google.com/sdk/gcloud/reference/topic/escaping.

title

(Required) A short string describing the purpose of the expression.

description

(Optional) Additional description for the expression.

--condition-from-file=PATH_TO_FILE

Path to a local JSON or YAML file that defines the condition. To see available fields, see the help for --condition. Use a full or relative path to a local file containing the value of condition.

GCLOUD WIDE FLAGS

These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.
