Release Notes

Kubermatic 2.24

v2.24.8

GitHub release: v2.24.8

Bugfixes

  • [ACTION REQUIRED] The latest Ubuntu 22.04 images ship with cloud-init 24.x package. This package has breaking changes and thus rendered our OSPs as incompatible. It’s recommended to refresh your machines with latest provided OSPs to ensure that a system-wide package update, that updates cloud-init to 24.x, doesn’t break the machines (#13359)

Updates

  • Update operating-system-manager to v1.4.2.

v2.24.7

GitHub release: v2.24.7

New Feature

  • Monitoring: introduce signout_redirect_url field to configure the URL to redirect the user to after signing out from Grafana (#13313)

Bugfixes

  • Enable local command for Enterprise Edition (#13333)
  • Fix template value for MachineDeployments in edit mode (#6669)
  • Hotfix to mitigate a bug in new releases of Chromium that causes browser crashes on mat-select component. For more details: https://issuetracker.google.com/issues/335553723 (#6667)
  • Fix Azure CCM not being reconciled because of labelling changes (#13334)
  • Improve Helm repository prefix handling for system applications; only prepend oci:// prefix if it doesn’t already exist in the specified URL (#13336)
  • Installer does not validate IAP client_secrets for Grafana and Alertmanager the same way it does for encryption_key (#13315)

  • Update to Go 1.21.9 (#13247)

Cleanup

  • Addons reconciliation is triggered more consistently for changes to Cluster objects, reducing the overall number of unnecessary addon reconciliations (#13252)

v2.24.5

GitHub release: v2.24.5

Bugfixes

  • Add images for Velero and KubeLB to mirrored images list (#13198)

  • Fix a bug where dedicated credentials were incorrectly being required as mandatory input when editing vSphere provider settings for a cluster (#6567)

Chore

Design

  • Improve compatibility with cluster-autoscaler 1.27.1+: Pods using temporary volumes are now marked as evictable (#13197)

v2.24.4

GitHub release: v2.24.4

Bugfixes

  • Fix the panic of the seed controller manager while checking CSI addon usage for user clusters, when a user cluster has PVs which were migrated from the in-tree provisioner to the CSI provisioner (#13126)

New Feature

  • We maintain now a dedicated docker image for the conformance tester, mainly for internal use (#13113)

v2.24.3

GitHub release: v2.24.3

Bugfixes

  • ACTION REQUIRED: For velero helm chart upgrade related change. If you use velero.restic.deploy: true, you will see new daemonset node-agent running in velero namespace. You might need to remove existing daemonset named restic manually (#12998)

v2.24.2

GitHub release: v2.24.2

Action Required

  • ACTION REQUIRED: User Cluster MLA cortex chart has been upgraded to resolve issues for cortex-compactor and improve stability of the User Cluster MLA feature. Few actions are required to be taken to use new upgraded charts (#12935)
    • Refer to Upstream helm chart values to see the latest default values
    • Some of the values from earlier values.yaml are now incompatible with latest version. They are removed in the values.yaml in the current chart. But if you had copied the original values.yaml to customize it further, you may see that kubermatic-installer will detect such incompatible options and churn out errors and explain that action that needs to be taken.
    • The memcached-* charts are now subcharts of cortex chart so if you provided configuration for memcached-* blocks in your values.yaml for user-mla, you must move them under cortex: block

Updates

  • Add support for Kubernetes v1.26.13, v1.27.10, v1.28.6 and set default version to v1.27.10 (#12982)

Bugfixes

  • If the seed cluster is using Cilium as CNI, create CiliumClusterwideNetworkPolicy for api-server connectivity (#12966)
  • Stop constantly re-deploying operating-system-manager when registry mirrors are configured (#12972)
  • The Kubermatic installer will now detect DNS settings based on the Ingress instead of the nginx-ingress LoadBalancer, allowing for other ingress solutions to be properly detected (#12934)

Removals

  • Remove 1.25 from list of supported versions on AKS (EOL on January 14th) (#12962)

v2.24.1

GitHub release: v2.24.1

Bugfixes

  • Increase the default resources for VPA components to prevent OOMs (#12887)

v2.24.0

GitHub release: v2.24.0

Before upgrading, make sure to read the general upgrade guidelines. Consider tweaking seedControllerManager.maximumParallelReconciles to ensure user cluster reconciliations will not cause resource exhaustion on seed clusters. A full upgrade guide is available from the official documentation.

Read Before Upgrading

  • ACTION REQUIRED: legacy backup controller has been removed. Before upgrading, please change to the backup and restore feature that uses backup destinations if the legacy controller is still in use (#12473)
  • s3-storeuploader has been removed (#12473)
  • OpenVPN for control plane to node connectivity has been deprecated. It will be removed in future releases of KKP. Upgrading all user cluster to Konnectivity is strongly recommended (#12691)
  • User clusters require upgrading to Kubernetes 1.26 prior to upgrading to KKP 2.24 (#12740)

Action Required

  • ACTION REQUIRED (EE ONLY): Update metering component to v1.1.1, fixing highly inaccurate data in cluster reports.

Ad-hoc reports for time frames that need correct consumption data can be generated by following our documentation (#12822)

API Changes

  • The field vmNetName in Cluster and Preset resources for vSphere clusters is deprecated and networks should be used instead (#12444)
