# Cluster Maintenance Config Resource Reference

The cluster maintenance config resource represents global configuration options for the agents enrolled into automatic updates (v1).

---

WARNING

`cluster_maintenance_config` configures Managed Updates v1, which are currently supported but will be superseded by Managed Updates v2. The `autoupdate_config` and `autoupdate_version` resources further down configure Managed Updates v2.
