gcloud beta iap web set-iam-policy

NAME
gcloud beta iap web set-iam-policy - set the IAM policy for an IAP IAM resource
SYNOPSIS
gcloud beta iap web set-iam-policy POLICY_FILE [--region=REGION --resource-type=RESOURCE_TYPE --service=SERVICE --version=VERSION] [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(BETA) This command replaces the existing IAM policy for an IAP IAM resource, given a file encoded in JSON or YAML that contains the IAM policy. If the given policy file specifies an "etag" value, then the replacement will succeed only if the policy already in place matches that etag. (An etag obtained via $ gcloud beta iap web get-iam-policy will prevent the replacement if the policy for the resource has been subsequently updated.) A policy file that does not contain an etag value will replace any existing policy for the resource.
