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.

  Type           Status  Reason
  ----           ------  ------
  Available      False   MinimumReplicasUnavailable
  Progressing    False   ProgressDeadlineExceeded
OldReplicaSets:  <none>
NewReplicaSet:   <none>

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.
