IAM policy for Pubsub Subscription

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

• google_pubsub_subscription_iam_policy: Authoritative. Sets the IAM policy for the subscription and replaces any existing policy already attached.
• google_pubsub_subscription_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 subscription are preserved.
• google_pubsub_subscription_iam_member: Non-authoritative. Updates the IAM policy to grant a role to a new member. Other members for the role for the subscription are preserved.

Note: google_pubsub_subscription_iam_policy cannot be used in conjunction with google_pubsub_subscription_iam_binding and google_pubsub_subscription_iam_member or they will fight over what your policy should be.

Note: google_pubsub_subscription_iam_binding resources can be used in conjunction with google_pubsub_subscription_iam_member resources only if they do not grant privilege to the same role.

google_pubsub_subscription_iam_policy

data "google_iam_policy" "admin" {
  binding {
    role    = "roles/editor"
    members = [
      "user:[email protected]",
    ]
  }
}

resource "google_pubsub_subscription_iam_policy" "editor" {
  subscription = "your-subscription-name"
  policy_data  = "${data.google_iam_policy.admin.policy_data}"
}

google_pubsub_subscription_iam_binding

resource "google_pubsub_subscription_iam_binding" "editor" {
  subscription = "your-subscription-name"
  role         = "roles/editor"
  members      = [
    "user:[email protected]",
  ]
}

google_pubsub_subscription_iam_member

resource "google_pubsub_subscription_iam_member" "editor" {
  subscription = "your-subscription-name"
  role         = "roles/editor"
  member       = "user:[email protected]"
}
