Kubernetes defines three concepts related to the implementation and enforcement of resource limits: resource quotas, limit ranges s, and requests. This call model has built-in support for timeouts, retries with exponential back-off, and lists that exceed the requested maximum size using the continuance functionality. Cron jobs is one of my favorite feature in Kubernetes. A client can specify a limit to the number of results to return, and if more results exist a token will be returned that allows the client to continue the previous list call repeatedly until all results are retrieved. In development: Azure Kubernetes Service (AKS) on Azure Stack Updated: October 22, 2018 Managed Kubernetes with Azure Kubernetes Service (AKS) on Azure Stack will make it even easier for Azure Stack users to manage and operate Kubernetes environments in the same ways as they do in Azure, without sacrificing portability. Although requests and limits can only be specified on individual Containers, it is convenient to talk about Pod resource requests and limits. Spring Retry provides an ability to automatically re-invoke a failed operation. Fine Grained Rate Limits.
