This document shows what are compatible Kubernetes, Terraform, and operating
systems versions with the current KubeOne version.
KubeOne works on any infrastructure out of the box. Natively supported
providers have support for additional features and are frequently tested with
the current KubeOne version. The additional features include the KubeOne
Terraform integration and the integration with Kubermatic machine-controller.
KubeOne supports AWS, Azure, DigitalOcean, GCP, Hetzner Cloud,
OpenStack, Packet, and VMware vSphere.
Supported Kubernetes Versions
Each KubeOne version supports Kubernetes versions supported by upstream at the
time of the KubeOne release. You can find more details about the upstream
support policy in the Version Skew Policy document.
In the following table you can find the supported Kubernetes versions for the
current KubeOne version.
* Kubernetes 1.17 has reached End-of-Life (EOL) and is not recommended
for new clusters.
Additionally, we do not recommend installing or upgrading to the following
- Releases older than 1.18.4 as they are affected by multiple CVEs
- On CentOS 7 releases older than 1.18.6 are not working
properly due to some networking-related issues
Supported Terraform Versions
The KubeOne Terraform integration requires Terraform v0.12.0 or newer.
Additionally, the example Terraform configs for some
providers may require a newer Terraform version:
- The example Terraform configs for AWS require Terraform v0.12.10 or newer
For more details, you can check the
