gcloud alpha pubsub topics set-iam-policy - set the IAM policy for a Cloud Pub/Sub Topic
gcloud alpha pubsub topics set-iam-policy TOPIC POLICY_FILE [GCLOUD_WIDE_FLAG ...]
(ALPHA) This command replaces the existing IAM policy for a topic, given a topic 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 topic has been subsequently updated.) A policy file that does not contain an etag value will replace any existing policy for the topic.
The following command will read an IAM policy defined in a JSON file 'policy.json' and set it for a topic with identifier 'my-topic'
$ gcloud alpha pubsub topics set-iam-policy my-topic policy.json
See https://cloud.google.com/iam/docs/managing-policies for details of the policy file format and contents.
