» google_client_openid_userinfo

Get OpenID userinfo about the credentials used with the Google provider, specifically the email.

When the https://www.googleapis.com/auth/userinfo.email scope is enabled in your provider block, this datasource enables you to export the email of the account you've authenticated the provider with; this can be used alongside data.google_client_config's access_token to perform OpenID Connect authentication with GKE and configure an RBAC role for the email used.

» Example Usage - exporting an email

provider "google" {
  scopes = [
    "https://www.googleapis.com/auth/compute",
    "https://www.googleapis.com/auth/cloud-platform",
    "https://www.googleapis.com/auth/ndev.clouddns.readwrite",
    "https://www.googleapis.com/auth/devstorage.full_control",
    "https://www.googleapis.com/auth/userinfo.email",
  ]
}

data "google_client_openid_userinfo" "me" {}

output "my-email" {
  value = "${data.google_client_openid_userinfo.me.email}"
}

» Example Usage - OpenID Connect w/ Kubernetes provider + RBAC IAM role

provider "google" {
  scopes = [
    "https://www.googleapis.com/auth/compute",
    "https://www.googleapis.com/auth/cloud-platform",
    "https://www.googleapis.com/auth/ndev.clouddns.readwrite",
    "https://www.googleapis.com/auth/devstorage.full_control",
    "https://www.googleapis.com/auth/userinfo.email",
  ]
}

data "google_client_openid_userinfo" "provider_identity" {}

data "google_client_config" "provider" {}

data "google_container_cluster" "my_cluster" {
  name   = "my-cluster"
  zone   = "us-east1-a"
}

provider "kubernetes" {
  load_config_file = false

  host = "https://${data.google_container_cluster.my_cluster.endpoint}"
  token = "${data.google_client_config.provider.access_token}"
  cluster_ca_certificate = "${base64decode(data.google_container_cluster.my_cluster.master_auth.0.cluster_ca_certificate)}"
}

resource "kubernetes_cluster_role_binding" "user" {
  metadata {
    name = "provider-user-admin"
  }

  role_ref {
    api_group = "rbac.authorization.k8s.io"
    kind      = "ClusterRole"
    name      = "cluster-admin"
  }

  subject {
    kind = "User"
    name = "${data.google_client_openid_userinfo.provider_identity.email}"
  }
}
