github kubermatic/kubeone v1.0.4

Attention Needed

  • KubeOne now creates a dedicated secret with vSphere credentials for kube-controller-manager and vSphere Cloud Controller Manager (CCM). This is required because those components require the secret to adhere to the expected format.
    • The new secret is called vsphere-ccm-credentials and is deployed in the kube-system namespace.
    • This fix ensures that you can use all vSphere provider features, for example, volumes and having cloud provider metadata/labels applied on each node.
    • If you're upgrading an existing vSphere cluster, you should take the following steps:
    • Upgrade the cluster without changing the cloud-config. Upgrading the cluster creates a new Secret for kube-controller-manager and vSphere CCM.
    • Change the cloud-config in your KubeOne Configuration Manifest to refer to the new secret.
    • Upgrade the cluster again to apply the new cloud-config, or change it manually on each control plane node and restart kube-controller-manager and vSphere CCM (if deployed).
    • Note: the cluster can be force-upgrade without changing the Kubernetes version. To do that, you can use the --force-upgrade flag with kubeone apply, or the --force flag with kubeone upgrade.
  • The example Terraform config for vSphere now has disk.enableUUID option enabled. This change ensures that you can mount volumes on the control plane nodes.
    • WARNING: If you're applying the latest Terraform configs on an existing infrastructure/cluster, an in-place upgrade of control plane nodes is required. This means that all control plane nodes will be restarted, which causes a downtime until all instances doesn't come up again.
