A container cluster contains a minimum of three controller nodes (including one master node) and a minimum of one worker node.
The controller nodes manage and control the operations of the cluster. You must specify A cluster has only one master node. You deploy components that manage and control the operation of the cluster on the controller nodes and must specify one of them as the master node.
The worker nodes run applications or services. You deploy applications or services on the worker nodes.
All these types of nodes can be physical servers or cloud hosts. You must install the system ISO image on them.
By default, the system platform components are deployed in container cluster default. You can add or remove nodes to increase or decrease the cluster capacity. You can also incorporate external container clusters to deploy additional services or applications.
