要解决这个问题，您需要来自 官方红帽控制台站点 的有效 pull-secret，将此 pull secret 存储在本地可访问 Kubernetes API （服务节点）的机器上，然后运行：
oc set data secret/pull-secret -n openshift-config --from-file=.dockerconfigjson=<pull_secret_location.json>
oc set data secret/pull-secret -n openshift-config --from-file=.dockerconfigjson=<pull_secret_location.json>

以上命令将在所有集群计算节点上提供身份验证信息，然后触发新的 pod 部署来拉取容器镜像：
kubectl delete pod rabbitmq-server-0 -n openstack
kubectl delete pod rabbitmq-server-0 -n openstack

pod 应该可以成功拉取(pull)镜像。有关哪些容器 registry 需要什么类型身份验证的更多信息，请检查 官方文档。
