v1.8.5 - 2024-12-23

Changelog since v1.8.4

Note: the v1.8.4 release has been abandoned due to an issue with the deprecated goreleaser flags.

Changelog since v1.8.3

Changes by Kind

Feature

  • Add disable_auto_update option to example Terraform configs for AWS, Azure, Equinix Metal, OpenStack, and vSphere, used to disable automatic updates for all Flatcar nodes (#3393, @xmudrii)
  • Update OpenStack CCM and CSI driver to v1.30.2, v1.29.1 and v1.28.3 (#3488, @rajaSahil)

Other (Cleanup or Flake)

  • Use dedicated keyring for Docker repositories to solve apt-key deprecation warning upon installing/upgrading containerd (#3486, @kubermatic-bot)

Updates

operating-system-manager

  • Update operating-system-manager (OSM) to v1.5.3 (#3390, @kron4eg)

Others

v1.8.3 - 2024-09-17

Changelog since v1.8.2

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

  • Fix vSphere CCM and CSI images. The CCM images for versions starting with v1.28.0 are pulled from the new community-owned image repository. The CCM images for versions prior to v1.28.0, and the CSI images, are pulled from the Kubermatic-managed mirror on quay.io. If you have a vSphere cluster, we strongly recommend upgrading to the latest KubeOne patch release and running kubeone apply as soon as possible, because the old image repository (gcr.io/cloud-provider-vsphere) is not available anymore, hence it's not possible to pull the needed images from that repository (#3378, @xmudrii)
  • Example Terraform configs for Hetzner are now using cx22 instead of cx21 instance type by default. If you use the new Terraform configs with an existing cluster, make sure to override the instance type as needed, otherwise your instances/cluster will be destroyed (#3371, @kubermatic-bot)

v1.8.2 - 2024-08-08

Changelog since v1.8.1

Changes by Kind

Feature

  • Allow the configuration of the upstream cluster-autoscaler flags --enforce-node-group-min-size and --balance-similar-node-groups (#3306, @kubermatic-bot)

Bug or Regression

  • Do not put multiple identical tolerations on the CoreDNS deployment (#3298, @kubermatic-bot)
  • Use the RHEL-based upstream Docker package repository instead of the CentOS package repository as it's not maintained any longer (#3336, @kubermatic-bot)

Updates

CNI

  • Update Calico CNI to fix the CPU usage spike issues (#3326, @kron4eg)

machine-controller

  • Update machine-controller to 1.59.3. This update includes support for IMDSv2 API on AWS for the worker nodes managed by machine-controller (#3323, @xrstf)

Terraform Configs

  • Set HttpPutResponseHopLimit to 3 in the example Terraform configs for AWS for the control plane nodes and the static worker nodes in order to support the IMSD v2 API (#3329, @kubermatic-bot)

v1.8.1 - 2024-07-01

Changelog since v1.8.0

Changes by Kind

Feature

  • Add support for Kubernetes 1.30 (#3215, @kubermatic-bot)
  • Refactor the cluster upgrade process to adhere to the Kubernetes recommendations by updating ConfigMaps used by Kubeadm instead of providing the full config to Kubeadm itself. This change should not have any effect to cluster upgrades, but if you encounter any issue, please create an issue in the KubeOne repository (#3253, @kubermatic-bot)
  • KubeOne now runs kubeadm upgrade apply without the --certificate-renewal=true flag. This change should not have any effect to the upgrade process, but if you discover any issue, please create a new issue in the KubeOne repository (#3242, @kubermatic-bot)
  • Add default VolumeSnapshotClass for all supported providers as part of the default-storage-class addon (#3275, @kubermatic-bot)

Bug or Regression

  • Fix snapshot-webhook admitting non-supported objects (VolumeSnapshots and VolumeSnapshotContents). This fixes an issue that caused inability to create new VolumeSnapshots (#3275, @kubermatic-bot)
  • Ensure apparmor-utils package is installed on Ubuntu as it's required for kubelet to function properly (#3235, @kubermatic-bot)
  • Load the CA bundle before any addon installations to resolve issues with untrusted TLS connections in environments with self-signed certificates (#3247, @kubermatic-bot)
  • Fix deletion issues for local Helm charts (#3268, @kubermatic-bot)

Updates

  • Update Canal CNI to v3.27.3 (#3200, @kubermatic-bot)
  • Bind the csi-snapshotter image to v8.0.1 for all providers that are supporting snapshotting volumes (#3270, @kubermatic-bot)

Terraform Configs

  • Fix the default Rocky Linux EC2 image filter query in the example Terraform configs for AWS (#3262, @kubermatic-bot)
  • Add bastion host support to the example Terraform configs for VMware Virtual Cloud Director (VCD) (#3278, @kubermatic-bot)

v1.8.0 - 2024-05-14

We're happy to announce a new KubeOne minor release — KubeOne 1.8! Please consult the changelog below, as well as, the following two documents before upgrading:

Changelog since v1.7.0

Urgent Upgrade Notes

(No, really, you MUST read this before you upgrade)

  • Refactor example Terraform configs for Hetzner to randomly generate the private network subnet in order to support creating multiple KubeOne clusters (#3152, @xmudrii)
  • The example Terraform configs for Azure have been migrated to use the Standard SKU for IP addresses. This is a breaking change for existing setups; in which case you should continue using your current SKU. Manual migration is possible by dissociating IP from the VM and LB, the migrating it, and assigning it back, however please consider all potential risks before doing this migration (#3149, @kron4eg)
  • Credentials defined in the credentials file now have precedence over credentials defined via environment variables. This change is made to match the behavior that's already documented in the KubeOne docs. If you use both the credentials file and the environment variables, we recommend double-checking your credentials file to make sure the credentials are up to date, as those credentials will be applied on the next kubeone apply run (#2991, @kron4eg)
  • kured has been removed, you have to re-enable it back in form of helmRelease (#3024, @kron4eg)
  • OSM: The latest Ubuntu 22.04 images on Azure have modified the configuration for cloud-init and how it accesses its datasource in Azure, in a breaking way. If you're having an Azure cluster, it's required to refresh your machines with the latest provided OSPs to ensure that a system-wide package update doesn't result in broken machines. (#3172, @xrstf)
  • Support for Docker is removed; containerRuntime.docker became a no-op. (#3008, @kron4eg)

  • Extract csi-external-snapshotter into its own addon (#3016, @kron4eg)
  • Replace JSON6902 with Strategic Merge in Nutanix CSI driver (#3035, @kron4eg)
