我是 KFServing 和 Kubeflow 的新手。

我正在关注https://github.com/kubeflow/kfserving/tree/master/docs/samples/v1alpha2/tensorflow来部署一个简单的推理服务。

但是，在查看日志时，我找不到容器存储初始化程序。我的预测服务 pod 拥有的唯一容器是 kfserving 和 queue-proxy。

我目前在 IBM Cloud 上使用 Kubeflow 1.2 和 Kubernetes 1.17。

storage-initializer是一个init container，所以如果你描述了这个 pod，你不会在containerspod spec 的部分中找到它，而是在部分中找到它initContainers。

$ kubectl get pod flowers-sample-predictor-default-00002-deployment-58bb9557sf7g2 -o json | jq .status.initContainerStatuses
[
  {
    "containerID": "docker://e40e5f86401b3715118b873fec4ae6c3ef57765ffbb5c9ab48757234c4f53b6f",

      }
    }
  }
]

我不熟悉model您使用的标签，您可以直接使用app标签或 pod 名称重试吗？

$ kubectl logs -l app=flowers-sample-predictor-default-00002 -c storage-initializer
