Attention Needed

  • [BREAKING/ACTION REQUIRED] The kubeone reset command requires an explicit confirmation like the apply command starting with this release
    • Running the reset command requires typing yes to confirm the intention to unprovision/reset the cluster
    • The command can be automatically approved by using the --auto-approve flag
  • [BREAKING/ACTION REQUIRED] Upgrade Terraform to 1.0.0. The minimum Terraform version as of this KubeOne release is v1.0.0. (#1368)
  • [BREAKING/ACTION REQUIRED] Use AdmissionRegistration v1 API for machine-controller-webhook. The minimum supported Kubernetes version is now 1.16. (#1290)
    • Since AdmissionRegistartion v1 got introduced in Kubernetes 1.16, the minimum Kubernetes version that can be managed by KubeOne is now 1.16. If you're running the Kubernetes clusters running 1.15 or older, please use the older release of KubeOne to upgrade those clusters
  • KubeOne Addons can now be organized into subdirectories. It currently remains possible to put addons in the root of the addons directory, however, this is option is considered as deprecated as of this release. We highly recommend all users to reorganize their addons into subdirectories, where each subdirectory is for YAML manifests related to one addon.
