Cluster Roles¶
DaoCloud Enterprise 5.0 categorizes clusters based on different functionalities to help users better manage IT infrastructure.
Global Service Cluster¶
This cluster is used to run DCE 5.0 components such as Container Management, Global Management, Insight, Container Registry. It generally does not carry business workloads.
| Supported Features | Description |
|---|---|
| K8s Version | 1.22+ |
| Operating System | RedHat 7.6 x86/ARM, RedHat 7.9 x86, RedHat 8.4 x86/ARM, RedHat 8.6 x86; Ubuntu 18.04 x86, Ubuntu 20.04 x86; CentOS 7.6 x86/AMD, CentOS 7.9 x86/AMD |
| Full Lifecycle Management | Supported |
| K8s Resource Management | Supported |
| Cloud Native Storage | Supported |
| Cloud Native Network | Calico, Cillium, Multus, and other CNIs |
| Policy Management | Supports network policies, quota policies, resource limits, disaster recovery policies, security policies |
Management Cluster¶
This cluster is used to manage worker clusters and generally does not carry business workloads.
- Classic Mode deploys the global service cluster and management cluster in different clusters, suitable for multi-data center, multi-architecture enterprise scenarios.
- Simple Mode deploys the management cluster and global service cluster in the same cluster.
| Supported Features | Description |

| Policy Management | Supports network policies, quota policies, resource limits, disaster recovery policies, security policies |
Worker Cluster¶
This is a cluster created using Container Management and is mainly used to carry business workloads. This cluster is managed by the management cluster.
| Supported Features | Description |
|---|---|
| K8s Version | Supports K8s 1.22 and above |
| Operating System | RedHat 7.6 x86/ARM, RedHat 7.9 x86, RedHat 8.4 x86/ARM, RedHat 8.6 x86; Ubuntu 18.04 x86, Ubuntu 20.04 x86; CentOS 7.6 x86/AMD, CentOS 7.9 x86/AMD |

| Cloud Native Storage | Supported |
| Cloud Native Network | Calico, Cillium, Multus, and other CNIs |
| Policy Management | Supports network policies, quota policies, resource limits, disaster recovery policies, security policies |
Integrated Cluster¶
This cluster is used to integrate existing standard K8s clusters, including but not limited to self-built clusters in local data centers, clusters provided by public cloud vendors, clusters provided by private cloud vendors, edge clusters, Xinchuang clusters, heterogeneous clusters, and different DaoCloud clusters. It is mainly used to carry business workloads.
| Supported Features | Description |
|---|---|
| K8s Version | 1.18+ |
| Supported Vendors | VMware Tanzu, Amazon EKS, Redhat Openshift, SUSE Rancher, Alibaba ACK, Huawei CCE, Tencent TKE, Standard K8s Cluster, Daocloud DCE |
| Full Lifecycle Management | Not Supported |
| K8s Resource Management | Supported |
| Cloud Native Storage | Supported |
| Cloud Native Network | Depends on the network mode of the integrated cluster's kernel |
| Policy Management | Supports network policies, quota policies, resource limits, disaster recovery policies, security policies |
Note
A cluster can have multiple cluster roles. For example, a cluster can be both a global service cluster and a management cluster or a worker cluster.
