Question

我正在研究位于https://kubernetes.io/docs/tasks/job/coarse-parallel-processing-work-queue/#before-you-begin的粗略并行处理Kubernetes教程。我使用EC2实例在AWS上通过Rancher设置了集群。当我运行

 kubectl apply -f ./job.yaml
 kubectl describe jobs/job-wq-1

我收到以下输出

Name:           job-wq-1

目前我不确定如何解决。似乎没有成功。可能是由于我的Rancher成立了吗？我确实在本教程中注意到，注释是空白的，并且我的工作是输出的。

感谢您的帮助。我检查了错误日志，发现以下错误“登录到AMQP服务器：发生套接字错误”在构建docker映像时，使用旧版14.04版本的ubuntu似乎是一个问题。当我切换到ubuntu的18.04版本时，教程按预期完成。
