v1.5.6

Changelog since v1.5.5

Changes by Kind

Feature

• Update kubernetes-cni to v1.2.0 and cri-tools to v1.26.0. This fixes an issue with installing/updating packages when trying to install Kubernetes v1.26.1, v1.25.6, v1.24.10, and v1.23.16 (#2608, @xmudrii)

Checksums

SHA256 checksums can be found in the kubeone_1.5.6_checksums.txt file.

v1.5.5

Changelog since v1.5.4

Changes by Kind

Feature

• Update Terraform provider for VMware Cloud Director to v3.8.1 (#2584, @ahmedwaleedmalik)
• Add support for insecure HTTPS connection to the VMware Cloud Director API in example Terraform configs (#2584, @ahmedwaleedmalik)

Bug or Regression

• Fix AMI filter for CentOS 7 in Terraform configs for AWS (#2559, @xmudrii)
• Fix an issue where custom CA bundle was not being propagated to machine-controller-webhook (#2587, @kubermatic-bot)
• Remove the leftover /tmp/k1-etc-environment file. This fixes an issue with kubeone apply failing if the username is changed (#2563, @kubermatic-bot)
• Run kubeadm with increased verbosity unconditionally. This only changes the behavior if KubeOne is run without the verbose flag but kubeadm fails, in which case kubeadm is going to print more information about the issue (#2565, @kubermatic-bot)

Checksums

SHA256 checksums can be found in the kubeone_1.5.5_checksums.txt file.

v1.5.4

Important Registry Change Information

In November, we announced that we are changing all image references from k8s.gcr.io to registry.k8s.io to keep up with the latest upstream changes. This patch release includes this change. Please ensure that any mirrors you use are able to host registry.k8s.io and/or that firewall rules are going to allow access to registry.k8s.io to pull images before upgrading to this KubeOne patch release.

The December Kubernetes patch releases (1.25.5, 1.24.9, 1.23.15, and 1.22.17) are enforcing registry.k8s.io by default. Please keep this in mind if you're using an older KubeOne patch release with the latest Kubernetes patch releases. We strongly advise that you use KubeOne v1.5.4 or newer with the latest Kubernetes patch releases.

Changelog since v1.5.3

Changes by Kind

API Change

• Image references are changed from k8s.gcr.io to registry.k8s.io. This is done to keep up with the latest upstream changes. Please ensure that any mirrors you use are able to host registry.k8s.io and/or that firewall rules are going to allow access to registry.k8s.io to pull images before applying the next KubeOne patch releases. (#2505, @xmudrii)

Feature

• KubeOne is now built using Go 1.19.4 (#2526, @xmudrii)
• Update Canal to v3.23.5. This Canal release is supposed to fix an issue where Calico pods are crashing after upgrading from an older Calico version to a newer one (see the Known Issues document for more details) (#2539, @xmudrii)
• Update Cilium to v1.12.3 (#2534, @kubermatic-bot)
• Update etcd to 3.5.6 which includes a fix for the recently reported data inconsistency issue for a case when etcd crashes during processing defragmentation operation (#2499, @kubermatic-bot)
• Enable compact hash checks as per the recommendations from etcd for detecting data corruption (#2499, @kubermatic-bot)
• Validate support for Kubernetes patch releases 1.24.9, 1.23.15, and 1.22.17. Upgrading to Kubernetes 1.24.9 is strongly advised because it's built with Go 1.18.9 which includes fixes for CVE-2022-41720 and CVE-2022-41717 (#2532, @xmudrii)

Bug or Regression

• Fix NPE in probes (#2484, @kubermatic-bot)
• Fix a panic (NPE) when determining if it is safe to repair a cluster when there's no kubelet or kubelet systemd unit on the node (#2495, @kubermatic-bot)
• Use the pause image from registry.k8s.io for all Kubernetes releases (#2529, @kubermatic-bot)

v1.5.3

Important Registry Change Information

For the next series of KubeOne and KKP patch releases, image references will move from k8s.gcr.io to registry.k8s.io. This will be done to keep up with the latest upstream changes. Please ensure that any mirrors you use are able to host registry.k8s.io and/or that firewall rules are going to allow access to registry.k8s.io to pull images before applying the next KubeOne patch releases. This is not included in this patch release but just a notification of future changes.

Important Security Information

Kubernetes releases prior to 1.25.4, 1.24.8, 1.23.14, and 1.22.16 are affected by two Medium CVEs in kube-apiserver: CVE-2022-3162 (Unauthorized read of Custom Resources) and CVE-2022-3294 (Node address isn't always verified when proxying). We strongly recommend upgrading to 1.25.4, 1.24.8, 1.23.14, or 1.22.16 as soon as possible.

Changelog since v1.5.2

Changes by Kind

API Change

• .cloudProvider.csiConfig is now a mandatory field for vSphere clusters using the external cloud provider (.cloudProvider.external: true). .cloudProvider.csiConfig can be specified even if the in-tree provider is used, but the provided CSIConfig is ignored in such cases (a warning about this is printed) (#2447, @kubermatic-bot)

Feature

• Add allow_insecure variable (default false) to Terraform configs for vSphere. The value of this variable is propagated to the MachineDeployment template in output.tf (#2449, @xmudrii)
• Add a new addon parameter called HubbleIPv6 (true/false, default: true) for Cilium CNI used to enable/disable Hubble UI listening on an IPv6 interface (#2451, @kubermatic-bot)
• Update OpenStack CCM and CSI to v1.24.5 and v1.22.2 (#2445, @xmudrii)
• Update etcd to 3.5.5 or use the version provided by kubeadm if it's newer (#2443, @kubermatic-bot)

Other (Cleanup or Flake)

• Expose machine-controller metrics port (8080/TCP), so Prometheus ServiceMonitor can be used for scraping (#2439, @kubermatic-bot)
• Make volume size for worker nodes configurable in Terraform configs for AWS (50 GB by default) (#2450, @xmudrii)

Chore

• Rename generate-internal-groups Make target to update-codegen (#2450, @xmudrii)
• KubeOne is now built using Go 1.19.3 (#2462, @xmudrii)
