部署无法重新创建成功的副本集 [英] deployment fails to recreate a successful replicaset

问题描述

我们正在使用Kubernetes 1.8在云提供商中部署我们的软件.通常，在部署特定的Pod模板时，部署无法创建成功的副本集，并且不会创建任何实例.我找不到比kubectl描述部署更好的描述.

We are using Kubernetes 1.8 to deploy our software in a cloud provider. Frequently, when deploying a specific pod-template, the deployment fails to create a successful replicaset and no instance is created. I am not able to find a better description than kubectl describe deploy.

推荐答案

昨天我遇到了类似您的错误，最后发现可以通过使用命令kubectl get pod YOUR_POD_NAME -o yaml从pod中获取与部署相对应的错误消息.您可以在那里查看状态和错误消息.

I got a similar error like yours yesterday and finally figured out that I could get error message from the pod corresponds with the deployment by using command kubectl get pod YOUR_POD_NAME -o yaml. You can check the status and error message there.
