# Platform Operator

Starting with Domino 6.0.0, the Platform Operator is the **only** supported path for managing your Domino cluster’s service layer.

This includes:

* Installing Domino.

* Upgrading Domino.

* Keeping your Domino cluster in sync with the desired state.

The Platform Operator is constituted of a few components:

* The Operator itself, which is packaged as a Helm chart.

* The `ddlctl` command line interface.

The `ddlctl` command line can be used for:

* Bootstrapping a new (or existing) Domino cluster with the operator and Domino custom resource.

* Installing and/or upgrading the operator.

* Installing and/or upgrading Domino.

* Interacting with Domino resources.
