 This open source is the SaaS of BCS, which is the BCS product layer service. It provides a friendly interface for visualizing the project cluster, nodes, namespaces, deployment configuration, docker registry, application, etc. Operation management, and provides a command line service that WebConsole can quickly view the status of the cluster. It supports the deployment and management of K8S applications using Helm for K8S cluster mode.
