kubermatic/kubeone v1.4.0-rc.1

on GitHub

Attention Needed

• Unconditionally deploy AWS, AzureDisk, AzureFile, and vSphere CSI drivers if the Kubernetes version is 1.23 or newer (#1831)
  • Those providers have the CSI migration enabled by default in Kubernetes 1.23, so the CSI driver will be used for all volumes operations
• Unconditionally deploy DigitalOcean, Hetzner, Nutanix, and OpenStack Cinder CSI drivers (#1831)
  • OpenStack has the CSI migration enabled by default since Kubernetes 1.18, so the CSI driver will be used for all operations
• [BREAKING] The default AMI for CentOS in Terraform configs for AWS has been changed to Rocky Linux. If you use the new Terraform configs with an existing cluster, make sure to bind the AMI as described in the production recommendations document (#1809)

Added

• Include darwin/arm64 and linux/arm64 builds in release artifacts (#1821)
• Allow providing operating system via the API (#1809)

• Unconditionally deploy AWS, AzureDisk, AzureFile, and vSphere CSI drivers if the Kubernetes version is 1.23 or newer (#1831)
  • Those providers have the CSI migration enabled by default in Kubernetes 1.23, so the CSI driver will be used for all volumes operations
