gcloud compute reservations remove-iam-policy-binding my-reservation --zone=ZONE --member='user:test-user@gmail.com' --role='roles/compute.securityAdmin'

To remove an IAM policy binding which expires at the end of the year 2018 for the role of 'roles/compute.securityAdmin' and the user 'test-user@gmail.com' with reservation 'my-reservation' and zone 'ZONE', run:

gcloud compute reservations remove-iam-policy-binding my-reservation --zone=ZONE --member='user:test-user@gmail.com' --role='roles/compute.securityAdmin' --condition='expression=request.time <
 timestamp("2019-01-01T00:00:00Z"),title=expires_end_of_2018,descrip\

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:

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

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.

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.
