» IAM policy for GCE subnetwork

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

• google_compute_subnetwork_iam_policy: Authoritative. Sets the IAM policy for the subnetwork and replaces any existing policy already attached.
• google_compute_subnetwork_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 subnetwork are preserved.
• google_compute_subnetwork_iam_member: Non-authoritative. Updates the IAM policy to grant a role to a new member. Other members for the role for the subnetwork are preserved.

» google_compute_subnetwork_iam_policy

data "google_iam_policy" "admin" {
  binding {
    role = "roles/editor"

    members = [
      "user:jane@example.com",
    ]
  }
}

resource "google_compute_subnetwork_iam_policy" "subnet" {
    subnetwork  = "your-subnetwork-id"
    policy_data = "${data.google_iam_policy.admin.policy_data}"
}

» google_compute_subnetwork_iam_binding

  subnetwork = "your-subnetwork-id"
  role       = "roles/compute.networkUser"

  members = [
    "user:jane@example.com",
  ]
}

» google\compute_subnetwork_iam_member

resource "google_compute_subnetwork_iam_member" "subnet" {

  role       = "roles/compute.networkUser"
  member     = "user:jane@example.com"
}

» Argument Reference

The following arguments are supported:

• subnetwork - (Required) The name of the subnetwork.

• 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_compute_subnetwork_iam_binding can be used per role. Note that custom roles must be of the format [projects|organizations]/{parent-name}/roles/{role-name}.

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

• project - (Optional) The ID of the project in which the resource belongs. If it is not provided, the provider project is used.

• region - (Optional) The region of the subnetwork. If unspecified, this defaults to the region configured in the provider.

» Attributes Reference

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

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

» Import

For all import syntaxes, the "resource in question" can take any of the following forms:

• full self link or relative link (projects/{{project}}/region/{{region}}/subnetworks/{{name}})
• {{project}}/{{region}}/{{name}}
• {{region}}/{{name}} (project is taken from provider project)
• {{name}} (project and region are taken from provider project)

IAM member imports use space-delimited identifiers; the resource in question, the role, and the member identity, e.g.

$ terraform import google_compute_subnetwork_iam_member.subnet "project-name/region-name/subnetwork-name roles/compute.networkUser user:foo@example.com"

IAM binding imports use space-delimited identifiers; the resource in question and the role, e.g.

$ terraform import google_compute_subnetwork_iam_binding.subnet "project-name/region-name/subnetwork-name roles/compute.networkUser"

IAM policy imports use the identifier of the resource in question, e.g.

$ terraform import google_compute_subnetwork_iam_policy.subnet project-name/region-name/subnetwork-name
