Clust_mgr is an important compnent of KunlunBase. It provides a HTTP API for KunlunBase users to do cluster management, provisioning and monitor work, so that uses can install a cluster, a kunlun-server node, a storage shard or a kunlun-storage node by calling such APIs. Such capability enables users to integrate KunlunBase management and provisioning as part of their existing application or GUIs. Cluster_mgr also provide other important cluster maintenance background work to make sure the KunlunBase clusters it serves can work efficiently and reliably.
