Disk resource - The disk for which to add IAM policy binding to. The argumentsin 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 otherways.

To set theproject attribute:

• provide the argumentdisk on the command line with a fullyspecified name;
• provide the argument--project on the command line;
• set the propertycore/project.

This must be specified.

DISK

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

To set thedisk attribute:

• provide the argumentdisk on the command line.

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

--zone=ZONE

The name of the Google Compute Engine zone.

To set thezone attribute:

• provide the argumentdisk on the command line with a fullyspecified name;
• provide the argument--zone on the command line;
• set the propertycompute/zone.

--member=PRINCIPAL

The principal to add the binding for. Should be of the formuser|group|serviceAccount:email ordomain:domain.

Examples:user:test-user@gmail.com,group:admins@example.com,serviceAccount:test123@example.domain.com, ordomain:example.domain.com.

Some resources also accept the following special values:

• allUsers - Special identifier that represents anyone who is on theinternet, with or without a Google account.

--role=ROLE

Role name to assign to the principal. The role name is the complete path of apredefined role, such asroles/logging.viewer, or the role ID for acustom role, such asorganizations/{ORGANIZATION_ID}/roles/logging.viewer.

At most one of these can be specified:

--condition=[KEY=VALUE,…]

A condition to include in the binding. When the condition is explicitlyspecified asNone (--condition=None), a bindingwithout a condition is added. When the condition is specified and is notNone,--role cannot be a basic role. Basic roles areroles/editor,roles/owner, androles/viewer. For more on conditions, refer to the conditionsoverview guide:https://cloud.google.com/iam/docs/conditions-overview

When using the--condition flag, include the following key-valuepairs:

expression

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

If the condition expression includes a comma, use a different delimiter toseparate the key-value pairs. Specify the delimiter before listing the key-valuepairs. For example, to specify a colon (:) as the delimiter, do thefollowing:--condition=^:^title=TITLE:expression=EXPRESSION. Formore information, seehttps://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 availablefields, see the help for--condition. Use a full or relative pathto a local file containing the value of condition.
