on GitHub

Attention Needed

• [BREAKING] GCP: Default operating system for control plane instances is now Ubuntu 20.04 (#1576)
  • Make sure to bind control_plane_image_family to the image you're currently using or Terraform might recreate all your control plane instances
• [BREAKING] Azure: Default VM type is changed to Standard_F2 (#1528)
  • Make sure to bind control_plane_vm_size and worker_vm_size to the VM size you're currently using or Terraform might recreate all your instances

Changed

General

  • This fixes the issue causing machine-controller and machine-controller-webhook deployments to run with incorrect flags
  • If you created your cluster with KubeOne 1.2 or older, and already upgraded to KubeOne 1.3, we recommend running kubeone apply again with KubeOne 1.3.2 or newer to properly reconcile machine-controller deployments
