kubermatic/kubeone v1.4.0-beta.0

on GitHub

Attention Needed

• KubeOne 1.4.0-beta.0 introduces the new KubeOneCluster v1beta2 API
  • The new v1beta2 API is still under-development and might be changed before the KubeOne 1.4.0 release
  • We recommend and highly encourage testing the new API, but considering that the API might be changed before the final release, we don't recommend migrating production clusters to the new API yet
  • The migration for existing KubeOneCluster manifests is not yet available
  • The kubeone config print command now uses the new v1beta2 API
  • The existing KubeOneCluster v1beta1 API is considered as deprecated and will be removed in KubeOne 1.6+
  • Highlights:
    • The API group has been changed from kubeone.io to kubeone.k8c.io
    • The AssetConfiguration API has been removed from the v1beta2 API. The AssetConfiguration API can still be used with the v1beta1 API, but we highly recommend migrating away because the v1beta1 API is deprecated
    • The PodPresets feature has been removed from the v1beta2 API because Kubernetes removed support for PodPresets in Kubernetes 1.20
    • Packet (packet) cloud provider has been rebranded to Equinix Metal (equinixmetal). The existing Packet cluster will work with equinixmetal cloud provider, however, manual migration steps are required if you want to use new Terraform configs for Equinix Metal
    • A new ContainerRuntime API has been added to the v1beta2 API in order to support configuring mirror registries. This API is still work-in-progress and will mostly like be extended before the final release
• kubeone install and kubeone upgrade commands are considered as deprecated in favor of kubeone apply
  • install and upgrade commands will be removed in KubeOne 1.6+
  • We highly encourage switching to kubeone apply. The apply command has the same semantics and works in the same way as install/upgrade, with some additional checks to ensure each requested operation is safe for the cluster
• Support for Amazon EKS-D clusters has been removed starting from this release

Known Issues

• It's not possible to run kube-proxy in IPVS mode on Kubernetes 1.23 clusters using Canal/Calico CNI. Trying to upgrade existing 1.22 clusters using IPVS to 1.23 will result in a validation error from KubeOne
  • More information about this issue can be found in the following Calico ticket: projectcalico/calico#5011
