Kubernetes Changelog

Validated on 23 June 2020 • Posted on 15 May 2019

DigitalOcean Kubernetes (DOKS) is a managed Kubernetes service that lets you deploy Kubernetes clusters without the complexities of handling the control plane and containerized infrastructure. Clusters are compatible with standard Kubernetes toolchains and integrate natively with DigitalOcean Load Balancers and block storage volumes.

We offer the latest version of Kubernetes and earlier patch levels of the latest minor version.

This page lists notable changes for each available version below, as well as archives of changes for unavailable versions.

1.18.x

Important Upgrade Notes For Volume Snapshot Users

Starting with DigitalOcean Kubernetes 1.18, alpha versions of volume snapshots are no longer supported. If existing volume snapshots meet the upgrade requirements, they will be converted automatically to the beta version of a volume snapshot when upgrading a cluster to 1.18.

Alpha versions of volume snapshots can continue to be used with versions prior to 1.18.

Please consult the volume snapshots migration notes before upgrading.
