Release v13.0.0 has been published

by Steve Starke

Hi! We're happy to announce that Tarook v13.0.0 [1] has been published! Some notable changes, amongst others: - Options for flexible kubelet configuration have been added on differing levels of granularity. - Policies in the Vault backend must be updated. - The "KUBECONFIG" variable is now set by our direnv layout. - The nix-channel has been bumped to 25.11. - The Ansible playbooks have been made compatible with Ansible 12. - Nodes which are already cordoned before a rollout are not uncordoned on system or Kubernetes upgrades anymore. - The default Helm chart version of Hashicorp Vault has been bumped. Upgrading the Vault instances requires manual steps [2]. - The minimum Helm chart version of kube-prometheus-stack is now 68.4.0. - IPSec cleanup tasks have been fixed. Support for IPSec is deprecated and will be removed soon. Notable changes specifically for clusters on OpenStack: - The VolumeSnapshotClass "csi-cinder-snapclass" now allows snapshots of attached volumes. Notable changes specifically for development setups: - In setups using a local Vault container [3], the Vault certificates must be removed and regenerated. The easiest way to achieve that is to setup a new development cluster repository. Checkout the release notes [4] for details!
