红帽全球峰会4.4. 先决条件
您必须在托管 OpenShift Container Platform 集群的位置（如 Red Hat Quay）中有一个支持 Docker v2-2 的容器镜像 registry。
注意如果使用 Red Hat Quay，则必须在 oc-mirror 插件中使用 3.6 或更高版本。如果您有 Red Hat Quay 权利，请参阅有关部署 Red Hat Quay for 概念验证 的文档，或使用 Red Hat Quay Operator。如果您需要额外的帮助来选择并安装 registry，请联络您的销售代表或红帽支持。
如果您还没有容器镜像 registry，OpenShift Container Platform 可以为订阅者提供一个 mirror registry for Red Hat OpenShift。您的订阅中包含 mirror registry for Red Hat OpenShift，它是一个小型容器 registry，可用于在断开连接的安装中镜像 OpenShift Container Platform 所需的容器镜像。
