This document lists the available operating system (OS) image families that you
can use in Cluster Director, their end of support (EOS) dates, and their patch
release notes.

To help ensure that your clusters remain operational and receive security
updates, you must update the nodesets or managed instance groups (MIGs) in your
clusters to use a supported image family. For more information about the
lifecycle of an image family in Cluster Director, see
[Image family lifecycle](https://docs.cloud.google.com/cluster-director/docs/os-images.md.txt#lifecycle).

## Supported image families
