» IAM policy for Pubsub Topic

Three different resources help you manage your IAM policy for pubsub topic. Each of these resources serves a different use case:

• google_pubsub_topic_iam_policy: Authoritative. Sets the IAM policy for the topic and replaces any existing policy already attached.
• google_pubsub_topic_iam_binding: Authoritative for a given role. Updates the IAM policy to grant a role to a list of members. Other roles within the IAM policy for the topic are preserved.
• google_pubsub_topic_iam_member: Non-authoritative. Updates the IAM policy to grant a role to a new member. Other members for the role for the topic are preserved.
