从 OpenShift SDN 到 OVN-Kubernetes 的有限实时迁移

Solution In Progress - Updated -

Issue

Red Hat OpenShift Container Platform 4.16 是支持 OpenShiftSDN 的最终版本 (参考)。Red Hat OpenShift Container Platform 需要新的安装(从 4.15 版本开始)来使用 OVN-Kubernetes (参考)。使用 OpenShiftSDN 的现有集群可以继续升级直到 4.16 为止,但在升级到 Red Hat OpenShift Container Platform 4.17 前需要进行迁移。根据当前文档,可以将 OpenShiftSDN 迁移到 OVN-Kubernetes,但这需要集群范围的中断。

Environment

  • OpenShift Container Platform
    • 4.16
