红帽全球峰会5.7. hub 集群拓扑
在生产环境中，OpenShift Container Platform hub 集群必须高度可用，才能维护管理功能的高可用性。
- 限制和要求
为 hub 集群使用高可用性集群拓扑，例如：
- Compact (3 节点组合 control plane 和计算节点)
- Standard (3 control plane 节点 + N 计算节点)
- 工程考虑
- 在非生产环境中，单节点 OpenShift 集群可用于有限的 hub 集群功能。
- 单节点 OpenShift 不支持某些功能，如 Red Hat OpenShift Data Foundation。在这个配置中，一些 hub 集群功能可能不可用。
- 可选计算节点的数量可能会因特定用例的规模而异。
- 可以根据需要稍后添加计算节点。
