See documentation for the latest supported version 3 or the latest supported version 4.2.3. 主节点大小
主（master）节点对资源的要求取决于集群中的节点数量。以下推荐的主节点大小是基于 control plane 密度测试的结果。
| worker 节点数量 | CPU 内核 | 内存 (GB) |
|---|---|---|
| 25 | 4 | 16 |
| 100 | 8 | 32 |
| 250 | 16 | 96 |
重要
因为无法修改正在运行的 OpenShift Container Platform 4.4 集群中的主节点大小，所以您必须估计节点总数并在安装过程中使用推荐的主节点大小。
注意
在 OpenShift Container Platform 4.4 中，与 OpenShift Container Platform 3.11 及之前的版本相比，系统现在默认保留半个 CPU 内核（500 millicore）。确定大小时应该考虑这一点。
