Parameters

The following arguments are supported:

  • cluster - (Required) The name or relative resource id of the cluster to manage IAM policies for.

For google_dataproc_cluster_iam_member or google_dataproc_cluster_iam_binding:

  • member/members - (Required) Identities that will be granted the privilege in role. Each entry can have one of the following values:

    • allUsers: A special identifier that represents anyone who is on the internet; with or without a Google account.
    • allAuthenticatedUsers: A special identifier that represents anyone who is authenticated with a Google account or a service account.
    • user:[emailid]: An email address that represents a specific Google account. For example, alice@gmail.com or joe@example.com.
    • serviceAccount:[emailid]: An email address that represents a service account. For example, my-other-app@appspot.gserviceaccount.com.
    • group:[emailid]: An email address that represents a Google group. For example, admins@example.com.
    • domain:[domain]: A G Suite domain (primary, instead of alias) name that represents all the users of that domain. For example, google.com or example.com.
  • role - (Required) The role that should be applied. Only one google_dataproc_cluster_iam_binding can be used per role. Note that custom roles must be of the format [projects|organizations]/[parent-name]/roles/[role-name].

google_dataproc_cluster_iam_policy only:

  • policy_data - (Required) The policy data generated by a google_iam_policy data source.

  • project - (Optional) The project in which the cluster belongs. If it is not provided, Terraform will use the provider default.

  • region - (Optional) The region in which the cluster belongs. If it is not provided, Terraform will use the provider default.

In addition to the arguments listed above, the following computed attributes are exported:

  • etag - (Computed) The etag of the clusters's IAM policy.

Explanation in Terraform Registry

Three different resources help you manage IAM policies on dataproc clusters. Each of these resources serves a different use case:

  • google_dataproc_cluster_iam_policy: Authoritative. Sets the IAM policy for the cluster and replaces any existing policy already attached.
  • google_dataproc_cluster_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 cluster are preserved.
  • google_dataproc_cluster_iam_member: Non-authoritative. Updates the IAM policy to grant a role to a new member. Other members for the role for the cluster are preserved.

    Note: google_dataproc_cluster_iam_policy cannot be used in conjunction with google_dataproc_cluster_iam_binding and google_dataproc_cluster_iam_member or they will fight over what your policy should be. In addition, be careful not to accidentally unset ownership of the cluster as google_dataproc_cluster_iam_policy replaces the entire policy.

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