EXAMPLES
To grant a single role to a single principal for BUCKET:

To specify a custom role for a principal on BUCKET: 

gcloud alpha storage buckets add-iam-policy-binding gs://BUCKET --member=user:john.doe@example.com --role=roles/customRoleName
POSITIONAL ARGUMENTS
URL
URL of bucket to add IAM policy binding to.
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:test-user@gmail.com, group:admins@example.com, serviceAccount:test123@example.domain.com, 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
