红帽全球峰会第 6 章 Cluster Operators reference
This reference guide indexes the cluster Operators shipped by Red Hat that serve as the architectural foundation for OpenShift Container Platform. Cluster Operators are installed by default, unless otherwise noted, and are managed by the Cluster Version Operator (CVO). For more details on the control plane architecture, see Operators in OpenShift Container Platform.
Cluster administrators can view cluster Operators in the OpenShift Container Platform web console from the Administration
Cluster Operators are not managed by Operator Lifecycle Manager (OLM) and OperatorHub. OLM and OperatorHub are part of the Operator Framework used in OpenShift Container Platform for installing and running optional add-on Operators.
Some of the following cluster Operators can be disabled prior to installation. For more information see cluster capabilities.
6.1. Cluster Baremetal Operator
The Cluster Baremetal Operator is an optional cluster capability that can be disabled by cluster administrators during installation. For more information about optional cluster capabilities, see "Cluster capabilities" in Installing.
The Cluster Baremetal Operator (CBO) deploys all the components necessary to take a bare-metal server to a fully functioning worker node ready to run OpenShift Container Platform compute nodes. The CBO ensures that the metal3 deployment, which consists of the Bare Metal Operator (BMO) and Ironic containers, runs on one of the control plane nodes within the OpenShift Container Platform cluster. The CBO also listens for OpenShift Container Platform updates to resources that it watches and takes appropriate action.
