我尝试运行 kubeflow 示例（管道/pytorchjob 等），但它堆叠为ContainerCreating.

为此，我想查看 dockershim 和 docker 日志。有文件吗？

示例代码如下 https://github.com/kubeflow/pipelines/tree/master/samples/core/helloworld

kubectl create serviceaccount pipeline-runner
python3 hello_world.py
kubectl create -f hello_world.py.yaml

$ kubectl describe workflow.argoproj.io/my-first-pipeline-wgkg2

kubectl logs如下

$ kubectl logs my-first-pipeline-wgkg2-3423630397 -c wait
Error from server (BadRequest): container "wait" in pod "my-first-pipeline-wgkg2-3423630397" is waiting to start: ContainerCreating
$ kubectl logs my-first-pipeline-wgkg2-3423630397 -c main
Error from server (BadRequest): container "main" in pod "my-first-pipeline-wgkg2-3423630397" is waiting to start: ContainerCreating

在工作节点中之后，您可以docker ps查找containerid容器，然后查看日志docker logs containerid命令应该很有用。

还要查看工作节点中的 kubelet 日志，通过在工作节​​点中运行命令来查看是否有任何问题journalctl -u kubelet.service -f。

通常，您寻求的信息位于“kubectl describe事件”部分。但是在您的日志中，它似乎是空的。也许您的 pod 还没有安排好？
