红帽全球峰会16.6. 在节点上配置 Pod 网络
集群管理员可以通过修改相应节点配置映射的 networkConfig 部分中的参数来控制 节点上的 pod 网络设置 ：
networkConfig: mtu: 1450 networkPluginName: "redhat/openshift-ovs-subnet"
networkConfig:
mtu: 1450
networkPluginName: "redhat/openshift-ovs-subnet" 注意
您必须在所有 master 和作为 OpenShift Container Platform SDN 一部分的节点上更改 MTU 大小。另外，tun0 接口的 MTU 大小必须在属于集群的所有节点中相同。
