gcloud alpha pubsub subscriptions set-iam-policy

NAME
gcloud alpha pubsub subscriptions set-iam-policy - set the IAM policy for a Cloud Pub/Sub Subscription
SYNOPSIS
gcloud alpha pubsub subscriptions set-iam-policy SUBSCRIPTION POLICY_FILE [GCLOUD_WIDE_FLAG …]
DESCRIPTION
(ALPHA) This command replaces the existing IAM policy for a subscription, given a subscription and 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 get-iam-policy will prevent the replacement if the policy for the subscription has been subsequently updated.) A policy file that does not contain an etag value will replace any existing policy for the subscription.

EXAMPLES
The following command will read an IAM policy defined in 'policy.json' and set it for a subscription 'my-sub' 
gcloud alpha pubsub subscriptions set-iam-policy my-sub policy.json

See https://cloud.google.com/iam/docs/managing-policies for details of the policy file format and contents.
