复制链接链接已复制到粘贴板!
作为集群管理员，您可以设置集群范围的默认节点选择器来限制 pod 放置到特定的节点。
编辑 /etc/origin/master/master-config.yaml 中的 master 配置文件，并为默认节点选择器添加一个值。这应用到没有指定 nodeSelector 值的所有项目中创建的 pod：
... projectConfig: defaultNodeSelector: "type=user-node,region=east" ...
...
projectConfig:
defaultNodeSelector: "type=user-node,region=east"
...重启 OpenShift 服务以使更改生效：
master-restart api master-restart controllers
# master-restart api
# master-restart controllers
