I am trying to add a GKE cluster using Terraform 0.12.5 [this used to be fine on 0.11.7 as far as I can tell]
resource "google_container_cluster" "primary" {
name = "gke-${terraform.workspace}-cluster"
zone = "${var.region}-b"
initial_node_count = 3
network = "${var.vpc_name}"
subnetwork = "${var.subnet_name}"
addons_config {
horizontal_pod_autoscaling {
disabled = false
}
kubernetes_dashboard {
disabled = false
}
}
# getting a vpc-native network
ip_allocation_policy {
}
master_auth {
username = "${var.gke_master_user}"
password = "${var.gke_master_pass}"
}
node_config {
oauth_scopes = [
"https://www.googleapis.com/auth/compute",
"https://www.googleapis.com/auth/devstorage.read_only",
"https://www.googleapis.com/auth/logging.write",
"https://www.googleapis.com/auth/monitoring",
]
labels = {
env = "${var.gke_label[terraform.workspace]}"
}
disk_size_gb = 10
machine_type = "${var.gke_node_machine_type}"
tags = ["gke-node"]
}
}
I run this based on a service-account with the following roles
- roles/compute.networkAdmin
- roles/resourcemanager.projectCreator
- roles/storage.admin
However to my surprise I now get permission issues in building the GKE cluster.
1) deploy error: Not all instances running in IGM after 10.808470514s.

This service account [email protected] is created for a project and inherits of the original service account. It is not clear to me how to provide it with the correct roles / credentials.
