将 GKE 节点池设置为 auto_upgrade

Question

I'm running a kubernetes cluster on GKE. I'd like to enable auto_upgrade for each node pool and I'd like to do this in terraform. I'm not sure how.

The node pools are defined with terraform like this

module "main-gke-cluster" {
  source = "../modules/gke-cluster"

  cluster_name = local.stage_main_cluster_name
  // SNIP...

  node_pools = {

    default-pool = {
      machine_type = "e2-standard-2"
      image_type = "UBUNTU"
      initial_node_count = 1
      min_nodes = 0
      max_nodes = 10
      preemptible = true
      node_locations = [
        "europe-west4-a"
      ]
      labels = {}
      taints = []
      oauth_scopes = local.default_pool_scopes
      has_gpu = false
    }

I attempted to set auto_upgrade on the node pool like so

module "main-gke-cluster" {
  source = "../modules/gke-cluster"

  cluster_name = local.stage_main_cluster_name
  // SNIP...

  node_pools = {

    default-pool = {
      machine_type = "e2-standard-2"
      image_type = "UBUNTU"
      initial_node_count = 1
      min_nodes = 0
      max_nodes = 10
      auto_upgrade = true
      preemptible = true
      node_locations = [
        "europe-west4-a"
      ]
      labels = {}
      taints = []
      oauth_scopes = local.default_pool_scopes
      has_gpu = false
    }

ie I added an auto_upgrade parameter.

This appears to have no effect on the terraform plan .

Any idea what I'm missing here?

Assuming you are using the Jetstack gke-module , then by default node pools will be set to use auto-upgrade. But if you want to explicitly enable auto-upgrade, then I believe the parameter you want to use is " management_auto_upgrade ".
