REQUIRED FLAGS
--member=PRINCIPAL
The principal to remove the binding for. Should be of the form user|group|serviceAccount:email or domain:domain.

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

Deleted principals have an additional deleted: prefix and a ?uid=UID suffix, where UID is a unique identifier for the principal. Example: deleted:user:test-user@gmail.com?uid=123456789012345678901.

Some resources also accept the following special values:

  • allAuthenticatedUsers - Special identifier that represents anyone who is authenticated with a Google account or a service account.
--role=ROLE
The role to remove the principal from.
OPTIONAL FLAGS
At most one of these can be specified:
--all
Remove all bindings with this role and principal, irrespective of any conditions.
--condition=[KEY=VALUE,…]
The condition of the binding that you want to remove. When the condition is explicitly specified as None (--condition=None), a binding without a condition is removed. Otherwise, only a binding with a condition that exactly matches the specified condition (including the optional description) is removed. 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.
