Upgrading to v25.0

The v25.0 release of kubernetes-engine is a backwards incompatible release.

gce_pd_csi_driver is GA and enabled by default

gce_pd_csi_driver is now supported in GA modules and defaults to true. To opt out, set gce_pd_csi_driver to false.

  module "gke" {
-   source           = "terraform-google-modules/kubernetes-engine"
-   version          = "~> 24.0"
+   source           = "terraform-google-modules/kubernetes-engine"
+   version          = "~> 25.0"
...
+   gce_pd_csi_driver  = false
}

Use the created service account when creating autopilot clusters

When create_service_account is true pass the created service account to the cluster_autoscaling -> auto_provisioning_defaults block for the beta-autopilot-private-cluster / beta-autopilot-public-cluster modules.

This will mean that the Nodes will use the created service account, where previously the default service account was erronously used instead.

To opt out, set create_service_account to false

  module "gke" {
-   source           = "terraform-google-modules/kubernetes-engine"
-   version          = "~> 24.0"
+   source           = "terraform-google-modules/kubernetes-engine"
+   version          = "~> 25.0"
...
+   create_service_account  = false
}
