Description

Google keeps on bumping revision of available gke cluster version.
Their API supports a fuzzy logic to determine which version you want to build as seen in that link

Today, we want to be able to build consistently our cluster with the same major/minor versions of kube.
For example, I'd like to be able to specify building 1.11.6 and not 1.11.6-gke.5 which may or may not supported in a couple of days and break my pipelines.

Potential Terraform Configuration

resource "google_container_cluster" "controlPlane" {
    name               = "${var.cluster_name}"
    region             = "${var.cluster_region}"

    min_master_version = "1.11.5-gke.5"
[...]
}

resource "google_container_cluster" "controlPlane115" {
    name               = "${var.cluster_name}"
    region             = "${var.cluster_region}"

    min_master_version = "1.11.5"
[...]
}

resource "google_container_cluster" "controlPlaneLatest" {
    name               = "${var.cluster_name}"
    region             = "${var.cluster_region}"

    min_master_version = "latest"
[...]
}

Just to make sure, is this not already working for min_master_version?

min_master_version = "1.11.6" works for me. I changed it from the 1.11.N-gke.M style like 2 months ago.

For node version, I do keep the "1.11.6-gke.2" style.

You are correct, I was mistaken and the error message was indeed coming from my node pool and not from my control plane.

I'll close this issue as I'm now buliding my nodepools with version = "{....controlPlane.master_version}"
